What is Hantavirus?

  • The Hantaviruses are a family of viruses spread mainly by rodents. It is contracted by humans from infected rodents.
  • Cases of the Hantavirus in humans occur mostly in rural areas where forests, fields and farms offer suitable habitat for infected rodents.
  • A person can get infected if he/she comes in contact with a rodent that carries the virus.
  • In the US and Canada, for instance, the Hantavirus carried by the deer mouse is responsible for the majority cases of the Hantavirus infection.
  • Like this, there are various other kinds of Hantaviruses that find hosts in rodents, like the white-footed mouse and the cotton rat among others that may lead to infections in humans if transmitted.

Its origin

  • The Hantavirus is not novel and its first case dates back to 1993, according to the US Centre for Disease Control (CDC).
  • In the Americas, the family of viruses is known as ‘New World hantaviruses’.

Symptoms

  • A person infected with the virus may show symptoms within the first to eighth week after they have been exposed to fresh urine, faeces or the saliva of infected rodents.
  • Symptoms may include fever, fatigue, muscle aches, headaches, chills and abdominal problems.
  • Four to ten after being infected, late symptoms of HPS may start to appear, which include coughing and shortness of breath.

Mortality risk

  • It is the cause of Hantavirus pulmonary disease (HPS), a severe respiratory disease. The HPS can be fatal and has a mortality rate of 38 per cent.
  • It remains unclear whether human-to-human transmission of the virus is possible.
  • There have been no reports of human-to-human transmission of Hantavirus in the US.
