West Nile virus detected in UK mosquitoes, here's all you need to know

The United Kingdom detected a deadly virus spreading through mosquitoes and this comes against the backdrop of surging Covid19 cases in South Asia.

UK Health Security Agency (UKHSA) confirmed the reports of the detection of the West Nile Virus (WNV) in mosquitoes collected in Britain for the first time.

What is the West Nile Virus (WNV)?

THE WNV is a part of the Flaviviridae virus family which includes dengue and yellow fever. It usually circulates among birds and mammals. The carriers of the virus are mosquitoes that bite infected birds. In rare cases, the virus is transmitted to humans or horses.

The presence of WNV was initially found in Europe, Africa, the Middle East, parts of Asia, Australia and the Americas. The virus has now found its presence in northern, and western regions of mainland Europe.

Symptoms:

In most cases, there may not necessarily be visible symptoms for those who are affected. However, around 20% of the infected can experience symptoms resembling mild flu-like signs such as fever, headache, muscle aches, swollen lymph nodes, and skin rashes, according to a BBC report.

Less than 1 per cent can lead to serious illnesses, particularly neurological complications.

"While this is the first detection of West Nile Virus in mosquitoes in the UK so far, it is not unexpected as the virus is already widespread in Europe," said Dr Meera Chand, a deputy director for travel health and infections at UKHSA.

Since 2000, seven cases have been reported that have travelled to other countries. As per the recent detection, no evidence of the virus circulating in birds or mosquitos has affected humans. Hence, the risk to the general public is currently assessed as very low. However, authorities have begun the initiative towards surveillance to monitor the situation.

Dr. Arran Folly, who led the project, noted, "The detection of West Nile virus in the UK is part of a wider changing landscape, where, in the wake of climate change, mosquito-borne diseases are expanding to new areas."

Preventive measures:

1. Protective clothing

Reduce skin exposure with the help of long sleeves, trousers and socks.

2. Avoid mosquito bites

The use of mosquito nets, insect repellents helps reduce the possibility of infection.

3. Remove stagnant water

As per a report in The Guardian, Aedes vexans mosquitos (known to carry WNV) are native to the UK and, while uncommon, their numbers can boom in summer in flooded river landscapes. Hence, it is advised to empty flower pots often or buckets where mosquitoes tend to breed.
