New Delhi: The Indian Council of Medical Analysis (ICMR) revealed a research a number of days in the past whereby the world acquired to learn about a virus which was reported in China and Vietnam up to now, and was present in India as nicely.
Nonetheless, the media sensationalised it as one other virus from China that would unleash an epidemic, fanning concern among the many people who find themselves attempting to return to phrases with the coronavirus pandemic.
The scientists of ICMR-Nationwide Institute of Virology (NIV), Pune, got here on document and informed IANS that the Cat Que Virus (CQV) can’t set off an epidemic.
Probably the most it might do is trigger “sporadic infections in rural areas”. In addition they concluded that CQV couldn’t be perceived as a significant public well being menace at the moment second.
“Our conclusion is that it can cause sporadic infections in rural areas where culicine vectors (a breed of mosquitoes) are found to breed. This virus doesn’t have the capabilities to cause an epidemic or pandemic,” stated DT Mourya, Director of Virology, NIV.
The CQV just isn’t new to India. Mourya informed IANS that scientists had first remoted CQV lengthy again in 1961 in Sagar district in Karnataka.
“It belongs to ‘Bunyaviridae’, which is one of the largest families of animal viruses. It houses 350 viruses, most of which are arthropod-borne. In the past, many viruses from this family have been isolated and reported from India such as Kaisodi virus, Umbre virus, Oya virus, Chittoor virus, Thottapalayam virus, Kaikalur virus, Thimiri virus, Sathuperi virus, Ganjam virus etc. Many closely related viruses from this group have been isolated from mosquitos, humans, birds and pigs across a vast geographic region,” Mourya stated.
Circumstances of CQV had been first reported in 2004 when it was remoted from mosquitoes throughout surveillance in Vietnam and later in Uganda, scientists knowledgeable.
The research revealed by ICMR detected CQV antibodies in two out of 883 human serum samples examined towards the virus. These samples had been collected from varied Indian states throughout 2014-2017.
Each the samples examined returned constructive for anti-CQV IgG antibody, indicating that they had been contaminated with the virus in some unspecified time in the future. The research confirmed that Indian mosquito breeds reminiscent of Ae. aegypti, Cx. quinquefasciatus and Cx. Tritaeniorhynchus had been inclined to the virus. Apart from, pigs and birds like Jungle Myna may act as a number to the virus.
The research additionally confirmed that the virus could possibly be transmitted when an individual is bitten by a mosquito. This virus is understood to trigger encephalitis-like signs just like Japanese encephalitis (JE).
“Cat Que virus is a rare infection and is known to be transmitted by certain culicine mosquito species that are also known to transmit JE virus. The natural cycle of this virus looks similar to JE virus. These viruses can cause acute, self-limiting febrile illness that generally gets clubbed into a viral fever and can be misdiagnosed due to similarity to many existing infections like dengue, chikungunya, malaria etc.,” Mourya defined.
Contemplating these isolations from the neighbouring nations — CQV in Culex mosquitoes in China and pigs of Vietnam — and assuming the unfold of vector mosquitoes in India, ICMR-NIV tried to develop diagnostic assays for speedy detection of this virus.
Pragya D Yadav, a scientist at NIV and one of many researchers of the research, stated that the analysis carried out is part of exploratory research of the institute and folks ought to understand it as a significant well being menace.
“The entire work is part of the exploratory research studies conducted by NIV as part of its research activity for developing proactive preparedness for new viruses. At the present moment, the Cat Que virus is not at all perceived as a major public health threat and does not merit enhanced attention,” stated Yadav.
“Lively an infection by CQV has been detected in India. The antibodies have been present in solely two individuals within the final seven years, and even these two folks by no means developed any signs of the illness. It is rather much less seemingly that the an infection by this explicit virus can unfold in people. We have to display screen extra samples to grasp its prevalence.
“Nonetheless, all ought to take precautions and observe security measures which embrace prevention of water assortment in crops, water coolers and close by environment,” stated Guduru Narayana Prudhvi Raj, Senior Marketing consultant and Normal Doctor at Apollo TeleHealth.
