Cat Que Virus

Note4Students

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.
