  • Forest Conservation Efforts – NFP, Western Ghats, etc.

    Centre raises alarm over Undemarcated Protected Forests in Chhattisgarh

    Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Undemarcated Protected Forests

    Mains level: Not Much

    The Union Ministry of Environment, Forest and Climate Change has objected to the transfer of thousands of hectares of land without following due process by Chhattisgarh from its Forest to the Revenue Department for setting up industries and for building road, rail, and other infrastructure.

    What is the news?

    • The Union Environment Ministry has warned that the land in question is “undemarcated protected forests”, which cannot be used for non-forest purposes without clearance under the Forest Conservation (FC) Act, 1980.

    ‘Types of Forests’ in Law

    • Broadly, state Forest Departments have jurisdiction over two types of forests notified under the Indian Forest (IF) Act, 1927:
    1. Reserve Forests (RF): where no rights are allowed unless specified and
    2. Protected Forests (PF): where no rights are barred unless specified
    • Certain forests, such as village or nagarpalika forests, are managed by state Revenue Departments.
    • The FC Act, 1980, applies to all kinds of forests, whether under the control of the Forest or the Revenue Department.
    • It requires statutory clearance before forests can be used for any non-forest purpose such as industry, mining, or construction.
    • In 1976, forests were included in List III (Concurrent List) under the Seventh Schedule of the Constitution.

    Chhattisgarh case

    • The recorded forest area in Chhattisgarh covers 44.21% of its geography.
    • The state government says it is constrained by the limited availability of land, particularly in the tribal regions, for development works.
    • Therefore, in May 2021, it sought a field survey to identify non-forest land — parcels smaller than 10 hectares with less than 200 trees per hectare.

    Orange, a grey area

    • It sought that the forests had been included by mistake in Orange Areas under the Forest Department.
    • This year, it announced that over 300 sq km of “Orange” area in the Bastar region had been handed over to the Revenue Department.
    • Under the zamindari system, villagers used local malguzari (livelihood concessions) forests for firewood, grazing, etc.
    • When zamindari was abolished in 1951, malguzari forests came under the Revenue Department.
    • In 1958, the government of undivided Madhya Pradesh notified all these areas as Protected Forest (PFs) under the Forest Department.
    • Through the 1960s, ground surveys and demarcations of these PFs continued — either to form blocks of suitable patches to be declared as Reserve Forests, or to denotify and return to the Revenue Department.
    • For this purpose, Madhya Pradesh amended the IF Act, 1927, in 1965 — when forests figured in the State List — to allow denotification of PFs.
    • The areas yet to be surveyed — undemarcated PFs — were marked in orange on the map.

    Policy jam

    • Since 2003, a case has been pending in the Supreme Court on rationalising these orange areas that have remained a bone of contention between the two Departments.
    • The transfer of PFs to the Revenue Department continued until 1976, when reports of illicit felling in Revenue areas prompted Madhya Pradesh to seek a fresh survey to shift quality forest patches.
    • But before this survey could be undertaken, the new government that came to power in the state in 1978 switched the focus to settling encroachments.
    • The FC Act came in 1980, and required central clearance for non-forest use of forest land.
    • This led to a situation where the rights of lakhs of villagers, including those settled by the government through pattas, remained restricted.

    After MP was split

    • Carved out of Madhya Pradesh in 2000, Chhattisgarh inherited its share of ‘orange’ areas.
    • Ranked second after Orissa in implementing the Forest Rights Act, 2006, the state has settled over 26,000 claims since 2019.
    • The logical next step, say officials who declined to be quoted, was to find land for the economic development of the tribal belt.
    • Chhattisgarh did not seek central clearance to transfer over 300 sq km to Revenue, they claim, because it did not have to.

    New definition of forests

    • In December 1996, the SC defined ‘forest’ after its dictionary meaning, irrespective of the status of the land it stands on.
    • It also defined forestland as any land thus notified on any government record irrespective of what actually stands on that land.
    • To meet this broad definition, Madhya Pradesh in 1997 framed a “practical yardstick” — an area no smaller than 10 hectares with at least 200 trees per hectare — to identify forests in Revenue areas for handing over to the Forest Department.
    • These non-forest areas, they claim, are now being identified and returned to the Revenue.

    Issues with such Un-forestation

    • The nature of vegetation changes over time.
    • After so many years, a visual survey cannot determine if a particular piece of land did not meet the definition of forest.
    • Once brought under the Forest Department, whether mistakenly or otherwise, an area gets the status of forestland as per the 1996 SC order, and hence comes under the FC Act, 1980.

    Options available for CG

    • Chhattisgarh, thanks to the 1965 amendment to the IF Act, can still denotify PFs unilaterally.
    • It may also vest management of any land with any department since the state owns all land within its boundaries.
    • But if the stated purpose is non-forest use — building industries and infrastructure — the state will anyway require central clearance under the FC Act, 1980.

    What lies ahead?

    • Clearance for non-forest use of forestland under the FC Act requires giving back twice the area for compensatory afforestation (CA) from Revenue to Forest.
    • That would defeat the very purpose of the state government’s action.
    • However, conversion of Forest to Revenue land has been exempted from CA under exceptional circumstances in the past.
    • For example, when enclaves were moved out of forests, the SC allowed those to be resettled at the edge of the forests, in the absence of suitable Revenue land, as revenue villages.
    • It will be a stretch, though, for such considerations to apply to thousands of hectares meant for industries.

  • Air Pollution

    Recovery of Ozone Layer achieves significant milestone

    Prelims Only | Enviro & Biodiversity | Mains Paper 1: Important Geophysical Phenomena

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Ozone, Ozone Hole

    Mains level: Ozone recovery

    The concentration of ozone-depleting substances in the atmosphere has reduced to reach a significant milestone this year.

    What is Ozone and Ozone Layer?

    • An ozone molecule consists of three oxygen atoms instead of the usual two (the oxygen we breathe, O2, makes up 21% of the atmosphere).
    • It only exists in the atmosphere in trace quantities (less than 0.001%), but its effects are very important.
    • Ozone molecules are created by the interaction of ultra-violet (UV) radiation from the Sun with O2 molecules.
    • Because UV radiation is more intense at higher altitudes where the air is thinner, it is in the stratosphere where most of the ozone is produced, giving rise to what is called the ‘ozone layer’.
    • The ozone layer, containing over 90% of all atmospheric ozone, extends between about 10 and 40km altitude, peaking at about 25km in Stratosphere.

    Why need Ozone Layer?

    • The ozone layer is very important for life on Earth because it has the property of absorbing the most damaging form of UV radiation, UV-B radiation which has a wavelength of between 280 and 315 nanometres.
    • As UV radiation is absorbed by ozone in the stratosphere, it heats up the surrounding air to produce the stratospheric temperature inversion.

    What is Ozone Hole?

    • Each year for the past few decades during the Southern Hemisphere spring, chemical reactions involving chlorine and bromine cause ozone in the southern polar region to be destroyed rapidly and severely.
    • The Dobson Unit (DU) is the unit of measure for total ozone.
    • The chemicals involved ozone depletion are chlorofluorocarbons (CFCs for short), halons, and carbon tetrachloride.
    • They are used for a wide range of applications, including refrigeration, air conditioning, foam packaging, and making aerosol spray cans.
    • The ozone-depleted region is known as the “ozone hole”.

    Tropical Ozone Hole

    • According to the study, the ozone hole is located at altitudes of 10-25 km over the tropics.
    • This hole is about seven times larger than Antarctica, the study suggested.
    • It also appears across all seasons, unlike that of Antarctica, which is visible only in the spring.
    • The hole has become significant since the 1980s. But it was not discovered until this study.

    What caused an ozone hole in the tropics?

    • Studies suggested another mechanism of ozone depletion: Cosmic rays.
    • Chlorofluorocarbon’s (CFC) role in depleting the ozone layer is well-documented.
    • The tropical stratosphere recorded a low temperature of 190-200 Kelvin (K).
    • This can explain why the tropical ozone hole is constantly formed over the seasons.

    Significance of the finding

    • The tropical ozone hole, which makes up 50 percent of Earth’s surface, could cause a global concern due to the risks associated with it.
    • It is likely to cause skin cancer, cataracts and other negative effects on the health and ecosystems in tropical regions.

    Try this PYQ

    Q.Consider the following statements:

    Chlorofluorocarbons, known as ozone-depleting substances are used:

    1. In the production of plastic foams
    2. In the production of tubeless tyres
    3. In cleaning certain electronic components
    4. As pressurizing agents in aerosol cans

  • Historical and Archaeological Findings in News

    Manusmriti: the controversial ancient Sanskrit text

    Prelims Only | History | Mains Paper 1: Arts & Culture

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Manusmriti

    Mains level: Not Much

    The Vice Chancellor of a renowned university recently criticized the Manusmriti, the ancient Sanskrit text, over its gender bias.

    What is the news?

    • The VC said that the Manusmriti has categorised all women as shudras, which is extraordinarily regressive.

    What is Manusmriti?

    • The Mānavadharmaśāstra, also known as Manusmriti or the Laws of Manu, is a Sanskrit text belonging to the Dharmaśāstra literary tradition of Hinduism.
    • Composed sometime between the 2nd century BCE and 3rd century CE, the Manusmriti is written in sloka verses, containing two non-rhyming lines of 16 syllabus each.
    • The text is attributed to the mythical figure of Manu, considered to be ancestor of the human race in Hinduism.
    • There has been considerable debate between scholars on the authorship of the text.
    • Many have argued that it was compiled by many Brahmin scholars over a period of time.
    • However, Indologist Patrick Olivelle argues that Manusmṛiti’s “unique and symmetrical structure,” means that it was composed by a “single gifted individual,” or by a “strong chairman of a committee” with the aid of others.

    What is the text about?

    (A) Social aspects

    • The Manusmriti is encyclopaedic in scope, covering subjects such as the social obligations and duties of the various castes and of individuals in different stages of life.
    • It seeks to govern the suitable social and sexual relations of men and women of different castes, on taxes, the rules for kingship, on maintaining marital harmony and the procedures for settling everyday disputes.
    • At its core, the Manusmriti discusses life in the world, how it is lived in reality, as well as how it ought to be.

    (B) Political aspects

    • They argue that the text is about dharma, which means duty, religion, law and practice.
    • It also discusses aspects of the Arthashashtra, such as issues relating to statecraft and legal procedures.
    • The aim of the text is to present a blueprint for a properly ordered society under the sovereignty of the king and the guidance of Brahmins.
    • It was meant to be read by the priestly caste and Olivelle argues that it would likely have been part of the curriculum for young Brahmin scholars at colleges.

    What is its significance?

    • By the early centuries of the Common Era, Manu had become, and remained, the standard source of authority in the orthodox tradition for that centrepiece of Hinduism, varṇāśrama-dharma (social and religious duties tied to class and stage of life)”.
    • Indologists argue that it was a very significant text for Brahmin scholars — it attracted 9 commentaries by other writers of the tradition, and was cited by other ancient Indian texts far more frequently than other dharmaśāstra.

    How did colonists consider this text?

    • European Orientalists considered the Manusmṛiti to be of great historical and religious significance as well. It was the first Sanskrit text to be translated into a European language, by the British philologist Sir William Jones in 1794.
    • Subsequently, it was translated into French, German, Portuguese and Russian, before being included in Max Muller’s edited volume, Sacred Books of the East in 1886.
    • For colonial officials in British India, the translation of the book served a practical purpose.
    • In 1772, Governor-General Warren Hastings decided to implement laws of Hindus and Muslims that they believed to be “continued, unchanged from remotest antiquity.
    • For Hindus, the dharmasastras were to play a crucial role, as they were seen by the British as ‘laws,’ whether or not it was even used that way in India.

    Why is it controversial?

    • The ancient text has 4 major divisions: 1) Creation of the world. 2) Sources of dharma. 3) The dharma of the four social classes. 4) Law of karma, rebirth, and final liberation.
    • The third section is the longest and most important section.
    • The text is deeply concerned with maintaining the hierarchy of the four-fold varna system and the rules that each caste has to follow.
    • Then, the Brahmin is assumed to be the perfect representative of the human race.
    • While Shudras, who are relegated to the bottom of the order, are given the sole duty of serving the ‘upper’ castes.
    • Some verses also contain highly prejudicial sentiments against women on the basis of their birth.
    • There are many verses in the text that are considered highly controversial.

    Dr. Ambedkar and Manusmriti

    • On December 25, 1927, Dr B R Ambedkar had famously burned the Manusmṛiti, which he saw as a source of gender and caste oppression.
    • However, he widely acknowledged that Manusmriti is NOT a religious decree but a social doctrine, manipulated since centuries to normalize oppression of the population.

  • International Space Agencies – Missions and Discoveries

    In news: James Webb Space Telescope

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: James Webb Space Telescope, Jupiter

    Mains level: Not Much

    The James Webb Space Telescope, NASA’s latest and most powerful telescope, has captured new images of our solar system’s largest planet, Jupiter, presenting it in a never before seen light.

    What is so special about snapping Jupiter?

    • The photographs have captured a new view of the planet, presenting in detail its massive storms, colourful auroras, faint rings and two small moons — Amalthea and Adrastea.
    • While most of us are familiar with the yellow and reddish-brown gas giant.
    • The JSWT’s Near-Infrared Camera, with its specialized infrared filters, has shown Jupiter encompassed in blue, green, white, yellow and orange hues.
    • Jupiter’s famous Great Red Spot, a storm so big that it could swallow Earth, appeared bright white in the image, since it was reflecting a lot of sunlight.
    • The brightness here indicates high altitude — so the Great Red Spot has high-altitude hazes, as does the equatorial region.
    • The numerous bright white ‘spots’ and ‘streaks’ are likely very high-altitude cloud tops of condensed convective storms.

    About James Webb Space Telescope

    • JWST is a space telescope jointly developed by NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA).
    • It is planned to succeed the Hubble Space Telescope as NASA’s flagship astrophysics mission.
    • It will conduct a broad range of investigations across the fields of astronomy and cosmology, including:
    1. Observing some of the most distant events and objects in the universe such as the formation of the first galaxies
    2. Detailed atmospheric characterization of potentially habitable exoplanets

    How is it different from other telescopes?

    • JWST is much more powerful and has the ability to look in the infrared spectrum, which will allow it to peer through much deeper into the universe, and see through obstructions such as gas clouds.
    • As electromagnetic waves travel for long distances, they lose energy, resulting in an increase in their wavelength.
    • An ultraviolet wave, for example, can slowly move into the visible light spectrum and the infrared spectrum, and further weaken to microwaves or radio waves, as it loses energy.
    • Hubble was designed to look mainly into the ultraviolet and visible regions of the electromagnetic spectrum.
    • JWST is primarily an infrared telescope, the first of its kind.

    Special features of JWST

    (1) Time machine in space

    • Powerful space telescopes, like JWST or the Hubble Telescope, are often called time machines because of their ability to view very faraway objects.
    • The light coming from those objects, stars or galaxies, which is captured by these telescopes, began its journey millions of years earlier.
    • Essentially, what these telescopes see are images of these stars or galaxies as they were millions of years ago.
    • The more distant the planet or star, the farther back in time are the telescopes able to see.

    (2) Farthest from Earth

    • JWST will also be positioned much deeper into space, about a million miles from Earth, at a spot known as L2.
    • It is one of the five points, known as Lagrange’s points, in any revolving two-body system like Earth and Sun, where the gravitational forces of the two large bodies cancel each other out.
    • Objects placed at these positions are relatively stable and require minimal external energy to keep them there. L2 is a position directly behind Earth in the line joining the Sun and the Earth.
    • It would be shielded from the Sun by the Earth as it goes around the Sun, in sync with the Earth.

    (3) Engineering marvel

    • JWST has one large mirror, with a diameter of 21 feet (the height of a typical two-storey building), that will capture the infra-red light coming in from the deep universe while facing away from the Sun.
    • It will be shielded by a five-layer, tennis court-sized, kite-shaped sunscreen that is designed to block the heat from Sun and ensure the extremely cool temperatures that the instruments are built to operate at.
    • Temperatures on the sun-facing side can get as high as 110°C, while the other side would be maintained at –200° to –230°C.
    • The extremely cold temperatures are needed to detect the extremely faint heat signals from distant galaxies.
    • The mirror as well as the sunscreen is so large they could not have fit into any rocket. They have been built as foldable items and would be unravelled in space.

    Automatic Number Plate Reader (ANPR) cameras for toll collection

    Prelims Only | Economics | Mains Paper 3: Infrastructure: Energy, Ports, Roads, Airports, Railways Etc.

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Automatic Number Plate Reader (ANPR)

    Mains level: Toll collection models in India

    In light of congestion at toll plazas, the Road Transport and Highways Ministry is now moving ahead with a plan to replace toll plazas with cameras that could read number plates, also known as Automatic Number Plate Reader (ANPR) cameras.

    ANPR cameras

    • The plan is to remove toll plazas on national highways and instead rely on ANPR cameras, which will read vehicle number plates and automatically deduct toll from the linked bank accounts of vehicle owners.
    • The model is simple: Entry and exit of toll roads will have cameras capable of reading number plates, and toll will be deducted based on these cameras.

    Can all number plates be read by the cameras?

    • Not all number plates in India can be read, and only those that have come after 2019 will be registered by the cameras.
    • The government, in 2019, had come up with a rule mandating passenger vehicles to have company-fitted number plates, and only these number plates can be read by cameras.
    • The government plans to come up with a scheme to replace older number plates.
    • A pilot of this scheme is underway and legal amendments to facilitate this transition are also being moved to penalise vehicle owners who skip toll plazas and do not pay.

    Current model for toll collection: FASTags

    • Currently, about 97 per cent of the total toll collection of nearly Rs 40,000 crore happens though FASTags — the remaining 3 per cent pay higher than normal toll rates for not using FASTags.
    • With FASTags, it takes about 47 seconds per vehicle to cross a toll plaza.
    • There’s a marked throughput enhancement – more than 260 vehicles can be processed per hour via electronic toll collection lane as compared to 112 vehicles per hour via manual toll collection lane, according to government data.
    • While FASTags have eased traffic at toll plazas across the country, congestion is still reported as there are toll gates that need to be crossed after authentication.

    Why such move?

    • Congestion at toll plazas on national highways continues to impact commuters despite 97 per cent of tolling happening through FASTags.
    • Apart from ANPR helping to ease congestion, the government is also looking at GPS technology as one of the options for toll collection.

    Are there issues with ANPR?

    • The success of ANPR cameras will depend on creating an ecosystem that is in sync with the requirements of the camera.
    • The biggest problem being faced during the trials is when things are written on number plates, beyond the nine digit registration number, such as ‘Govt of India/Delhi’ etc.
    • Another problem that ANPR cameras face is in reading number plates on trucks, as most of the time they are hidden or soiled etc.
    • A pilot on a key expressway has found that about 10 per cent of vehicles with such number plates are being missed by the ANPR cameras.

    Back2Basics: What is ‘FASTag’?

    • As per Central Motor Vehicles Rules, 1989, since 1st December 2017, the FASTag had been made mandatory for all registered new four-wheelers and is being supplied by the Vehicle Manufacturer or their dealers.
    • It has been mandated that the renewal of fitness certificate will be done only after the fitment of FASTag.
    • For National Permit Vehicles, the fitment of FASTag was mandated since 1st October 2019.
    • FASTags are stickers that are affixed to the windscreen of vehicles and use Radio Frequency Identification (RFID) technology to enable digital, contactless payment of tolls without having to stop at toll gates.
    • The tags are linked to bank accounts and other payment methods.
    • As a car crosses a toll plaza, the amount is automatically deducted, and a notification is sent to the registered mobile phone number.

    How does it work?

    • The device employs Radio Frequency Identification (RFID) technology for payments directly from the prepaid or savings account linked to it.
    • It is affixed on the windscreen, so the vehicle can drive through plazas without stopping.
    • RFID technology is similar to that used in transport access-control systems, like Metro smart card.
    • If the tag is linked to a prepaid account like a wallet or a debit/credit card, then owners need to recharge/top up the tag.
    • If it is linked to a savings account, then money will get deducted automatically after the balance goes below a pre-defined threshold.
    • Once a vehicle crosses the toll, the owner will get an SMS alert on the deduction. In that, it is like a prepaid e-wallet.

  • Indian Missile Program Updates

    Vertical Launch Short Range Surface-to-Air Missile (VL-SRSAM)

    Prelims Only | Science Tech | Mains Paper 3: Indigenization Of Technology

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: VL-SRSAM

    Mains level: Short range missiles development

    The Defence Research and Development Organisation (DRDO) and the Indian Navy has successfully flight-tested the indigenously developed Vertical Launch Short Range Surface-to-Air Missile (VL-SRSAM) from the Integrated Test Range (ITR) at Chandipur off the coast of Odisha.

    What is Vertical Launch Short Range Surface-to-Air Missile (VLSRSAM) ?

    • VL-SRSAM has been designed and developed jointly by three facilities of the DRDO for deployment of Indian Naval warships.
    • The missile has the capability of neutralising various aerial threats at close ranges including sea-skimming targets.
    • The tactic of sea skimming is used by various anti-ship missiles and some fighter jets to avoid being detected by the radars onboard warships.
    • For this, these assets fly as close as possible to sea surface and thus are difficult to detect and neutralise.

    Features of VL-SRSAM

    • The missile has been designed to strike at the high-speed airborne targets at the range of 40 to 50 km and at an altitude of around 15 km.
    • Its design is based on Astra missile which is a Beyond Visual Range Air to Air missile.
    • Two key features of the VL-SRSAM are cruciform wings and thrust vectoring.
    • The cruciform wings are four small wings arranged like a cross on four sides and give the projective a stable aerodynamic posture.
    • The thrust vectoring is an ability to change the direction of the thrust from its engine control the angular velocity and the attitude of the missile.
    • VL-SRSAM is a canisterised system, which means it is stored and operated from specially designed compartments.
    • In the canister, the inside environment is controlled, thus making its transport and storage easier and improving the shelf life of weapons

    Strategic significance of the missile

    • The launch was conducted from a vertical launcher against an electronic target at a very low altitude.
    • The flight path of the vehicle along with health parameters was monitored using a number of tracking instruments deployed by ITR, Chandipur.
    • The successful testing of these systems was crucial for future launches of the missile from Indian Naval Ships.

  • Zoonotic Diseases: Medical Sciences Involved & Preventive Measures

    Tomato Flu cases found in India

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Tomato Flu

    Mains level: Not Much

    With cases of tomato flu reported from at least four states — Kerala, Tamil Nadu, Haryana, and Odisha — the Union Health Ministry has issued a set of guidelines on prevention, testing, and treatment of the infection.

    Researchers believe that it is a different clinical presentation of hand-foot-and mouth disease (HFMD) caused by a group of enteroviruses (viruses transmitted through the intestine).

    What is Tomato Flu?

    • Tomato flu or tomato fever is characterized by fever, joint pain, and red, tomato-like rashes usually seen in children below the age of five years.
    • This is accompanied by other symptoms of viral fevers such as diarrhoea, dehydration, nausea and vomiting, and fatigue.
    • This was thought to be an aftereffect of dengue and chikungunya that is commonly seen in Kerala.
    • However, researchers now believe that it is HFMD caused by enteroviruses like Coxsackievirus A-6 and A-16.

    Is it very uncommon?

    • Tomato flu could be an after-effect of chikungunya or dengue fever in children rather than a viral infection.
    • It could also be a new variant of the viral hand, foot, and mouth disease, a common infectious disease targeting mostly children aged 1–5 years and immunocompromised adults.
    • HFMD is not a new infection, we have read about it in our textbooks. It is reported from time to time across the country, but it is not very common.

    Why is the infection spreading now?

    • There actually are more cases or because we are more vigilant about viral infections and testing after Covid-19.
    • Since the disease is self-limiting, doctors do not usually test for it.
    • There are so many viral infections in children, but we cannot — and there is no need to — test for each and every one of it.

    Which pathogen is causing it now? And how is the clinical presentation different?

    • The current HFMD cases are mainly caused by Coxsackievirus A-6 and A-16.
    • Another pathogen — Enterovirus71 — that also causes the disease is not very prevalent now, according to her.
    • This is good because the pathogen was known to lead to severe neurologic symptoms, including fatal encephalitis (brain inflammation).
    • In almost all cases, say 99.9% cases, the disease is self-limiting.
    • But, in a small number of cases it can lead to CNS (central nervous system) complications.

    Is there a treatment for the infection?

    • There is no specific treatment or vaccine available for the disease.
    • Those with the infection are treated symptomatically, such as prescription of paracetamol for fever.

    How can the infection be prevented?

    • As it happens mainly in children, the Centre’s advisory focuses on preventions in these age groups.
    • As per the advisory, anyone suspected to have the infection should remain in isolation for five to seven days after the onset of the symptoms.
    • It states that children must be educated about the infection and asked not to hug or touch other children with fever or rashes.
    • The children should be encouraged to maintain hygiene, stop thumb or finger sucking, and use a handkerchief for a running nose, the advisory states.
