West Nile Virus Linked to Meningitis Cases

Spread by mosquitoes, WNV is a risk during the summer months until the fall across the continental U.S. From California to Texas and New Hampshire, 36 states have reported WNS infections in people, birds or mosquitoes this year.

According to the latest Centers for Disease Control and Prevention update issued on July 24, 39 cases of WNV have been reported this year. Some 29 people were diagnosed with a neuroinvasive disease such as meningitis or encephalitis. California and Louisiana have seen the most cases in 2018, both with ten.

However, figures are likely to be far higher as most people infected do not show symptoms, and one in five people experience mild symptoms that the CDC is not notified of.

In most cases, those who catch WNV will experience symptoms such as nausea, fever, headache, body aches and a skin rash.

But in severe cases, WNV can target the nervous system, sparking conditions including meningitis, encephalitis paralysis and even death. According to the Centers for Disease and Control, one in 150 patients will develop the potentially deadly form of the virus.

Health officials across the country are rolling out programs to tackle WNV-carrying mosquitoes. On July 25, the Santa Clara County Vector Control District, which monitors infectious disease in the Californian county, announced spraying was scheduled for 11 p.m. on Thursday. Similar precautions were taken in Pittsburgh and Sacramento.

Anyone bitten by a mosquito carrying WNV can fall ill. But individuals aged over 50 or with chronic health conditions are most at risk.

As there is no vaccine or treatment for WNV, infected individuals must let the illness run its course. However, the side effects of a WNV infection can last for months to years. Half of individuals with the disease will be left with physical or cognitive problems a year after first contracting it. Memory loss, trouble walking and fatigue can linger long-term.

Mosquitoes become carriers of WNV if they feed on the blood of infected birds. Not all mosquitoes, therefore, carry WNV.

The best way to avoid catching WNV is to prevent mosquito bites, the CDC said. It advised the public to use insect repellent and wear long-sleeved shirts and pants in high-risk areas.

Other measures include removing mosquito habitats, such as standing water, from around the home, and ensuring the insects can't fly through gaps in windows and gaps in door screens.
