From UPSC perspective, the following things are important :
Prelims level : Cat Que Virus
Mains level : Not Much
In a study published in the Indian Journal of Medical Research, scientists have noted the presence of antibodies against the Cat Que virus (CQV) in two human serum samples.
Try this PYQ:
Q.Which one of the following statements is not correct?
(a) Hepatitis B virus is transmitted much like HIV.
(b) Hepatitis B, unlike Hepatitis C, does not have a vaccine.
(c) Globally, the number of people infected with Hepatitis B and C viruses is several times more than those infected with HIV.
(d) Some of those infected with Hepatitis B and C viruses do not show the symptoms for many years.
What is the Cat Que Virus?
- For CQV, domestic pigs are considered to be the primary mammalian hosts.
- Antibodies against the virus indicate that the virus has formed a “natural cycle” in the local area and has the ability to spread in pigs and other animal populations through mosquitoes.
- CQV belongs to the Simbu serogroup and infects both humans and economically important livestock species.
- It was first isolated in 2004 from mosquitoes during the surveillance of arbovirus activity in northern Vietnam.
- In this study, researchers reported a CQV strain (SC0806), which was isolated from mosquito samples collected in China in 2006 and 2008.
Impact on humans
- Humans can get infected through mosquitoes as well.
- In the study, scientists note that because of positivity in human serum samples and the replication capability of CQV in mosquitoes, there is only a “possible disease-causing potential” of CQV in the Indian scenario.
