The Western Neil virus was discovered in the genetic materials of mosquitoes collected in Britain for the first time, the UK Health Security Agency said.
The agency assessed the risks that the common people are exposed to as “very low” and said that there is no evidence of humans or that the virus has become a settler.
The disclosure in the mosquitoes collected in Nottinghamsheire follows warnings that the geographical boundaries of serious diseases transmitted by vectors, including the Western Nile virus, dengue and yellow fever, Move steadfast north Because of climate change.
“The discovery of the Western Nile virus in the United Kingdom is part of new changing regions where, in the wake of climate change, the borrowing parties extend to new regions,” said Dr. Aran Fuli, a target specialist in ARBOVIRAL at the APHA and the leadership of the monitoring program that tested the mosquitoes.
The Western Nile virus is usually found in birds and is usually traded Vexans Mosquitoes, which prefer bird bite, but in rare cases, can transmit the virus to humans or horses. Most human infections are without symptoms, as one in five people develop fever, headache, body pain and other flu -like symptoms and a very small percentage of developing severe neurological diseases such as brain inflammation or meningitis.
Vexans The mosquitoes are a citizen of the United Kingdom, and although their numbers can excel in the summer in the landscape of the submerged river. Experts suggest that the virus has reached an infected bird.
In order for the disease to become a settler, the climate is very important, because the virus is repeated more quickly when the weather is hot. In 15 ° C takes several months – longer than the average age of mosquitoes – for the virus to reach the infectious threshold. At 30 ° C, the same process takes two to three weeks, which means that the virus can be rooted in mosquitoes.
The virus was discovered through the incomplete radar program (discovery and response of the Arbovy virus in actual time) by APHA in Vexans The mosquitoes that Ukhsa collected from wetlands on the inactivity river near Gamston, NutinghamshereIn July 2023.
The mosquitoes were collected into groups from 10 to test, and fragments of the genetic materials of the Western Nile virus were identified in two gatherings. 198 other negative gatherings were. This is the first evidence of the Western Nile virus discovered in mosquitoes in the UK.
Western Nile virus is settler in different regions worldwide, including southern Europe, Africa, the Middle East, North America and Australia. In recent years, the geographical group of Western Nile virus has expanded to more northern and western regions in Europe from the mainland, as hot summer has become more frequent.
There were no cases of locally obtained Western Nile virus discovered in humans or horses in the United Kingdom yet, and there is no evidence indicating continuous circulation of the virus in birds or mosquitoes.
Disease control and control activities are enhanced in light of the results, and advice has been issued to health care professionals so that patients with encephalitis can be tested of an unknown cause as a preventive action.
“While this is the first disclosure of the Western Nile virus in the UK mosquitoes so far,” said Dr. Mira Chand, deputy UKHSA Director of Travel Health, Inflammations, and the Periodic and TB, Dr. The danger to the general public is currently evaluated as
“The immediate danger is not great for human health,” said Paul Hunter, a professor of medicine at East University.
