People should make efforts to protect themselves from mosquitoes as 20 cases of West Nile virus have been confirmed so far in 2015, say state health officials.

A report was released earlier this week to show that 10 of the cases were related to neuroinvasive disease, two to West Nile fever and eight were to asymptomatic, said the Louisiana Department of Health and Hospitals.

"It's critical for adults and children to wear mosquito repellent at all times while outdoors. Whether your children are playing sports, your family is outside grilling or you're doing yard work, be sure to protect yourself and your family", said state health officer Dr. Jimmy Guidry.

DHH believes that symptoms are exhibited in 90% of all West Nile cases, while about 10% develop West Nile fever. Few infected individuals are likely to show the serious symptoms associated with neuroinvasive disease.

The risk of complications is higher for people who are at least 65 years old, but health officials say that risk of infections looms over everyone.

Health officials advised people to use mosquito repellant, wear full sleeve shirts and pants while outside, avoid perfumes or colognes when outdoors, ensure no standing water around home, and clean and chlorinate swimming pools that are not being used.
