Our Views: West Nile virus back

Louisiana’s first reported human case of West Nile virus for this year underscores the importance of controlling mosquitoes this summer — and throughout the year.

A blood test recently detected a human case of West Nile virus in St. Bernard Parish.

Ninety percent of all people infected with the virus never get sick from it, public health officials have said. About 10 percent will develop flu-like symptoms, and a very small number of those infected develop more serious infections of the nervous system.

The virus is spread to humans through mosquitoes. That reality should prompt vigilance in controlling mosquitoes in south Louisiana.

Last year, Louisiana recorded 12 cases of West Nile virus, the fewest since tracking began in 2002. We hope that number continues to decline.

Mosquitoes can carry other diseases, and that should be an additional incentive for Louisiana residents to prevent mosquito breeding. The goal should be a healthy summer for everyone.
