Since being first reported in China’s Wuhan city in late 2019, coronavirus, or COVID-19, has spread worldwide, killing more than one million people. As of Tuesday, the fatal number in India is 96,318, while the total caseload is 6,145,292.

India’s top biomedical research body – the Indian Council of Medical Research (ICMR) – has expressed concern about another virus outbreak in China – the cat Q virus (CQV) in mosquitoes and pigs – of a global impact in worried position. The presence of CQV was found in so-called Culex mosquitoes in China and pigs in Vietnam, which, according to the study, indicates a possible susceptibility to viruses from Asian countries.

A study by ICMR published in a scientific journal called Indian Journal of Medical Research suggests that CQV can cause febrile disease, meningitis and pediatric encephalitis in humans.

“Anti-CVC IgG antibody positivity was tested in human serum samples and the replicative ability of CVC in mosquitoes indicated a possible disease of CVC in the Indian scenario. The study stated that screening of more human and swine serum samples using these assays is needed, to understand the prevalence of this neglected tropical virus.

Scientists at the National Institute of Virology, Pune under ICMR, found antibodies to the virus in two of the 883 human serum samples tested across the country. This indicates that both of these individuals had the virus at some point.

“All human serum samples (n = 1020) were tested for the presence of CVC using real-time RT-PCR which was found to be negative. Anti-CVC IgG antibody positivity was recorded in two of the 883 human serum samples tested. Virus susceptibility experiments indicated that three species of mosquitoes, namely Aedes aegypti, Culex quinquefacetas And Cx. tritaeniorhynchus “Supported multiplication of CQV by endocytosis as well as artificial membrane / oral feeding pathways”, reads the abstract of the study.

According to the ICMR, Indian mosquitoes are susceptible to CQV, which can also become a public health concern.
