Five more West Nile virus cases were reported Friday by the Mississippi Department of Health.

Those infected by the mosquito-borne virus lived in Adams, Forrest, Scott, Smith and Stone counties, a news release said.

Thirteen cases of West Nile virus have been reported in the state since April and one person has died.

The increase comes a day after the Centers for Disease Control announced West Nile virus cases are up four times over last year at this time with three deaths across the country.

Health officials had counted only 33 cases nationally by late July last year, but it turned out to be the worst season since the record year 2003.

At least 177 people died from West Nile in 2006 out of 4,269 cases, while 264 people died out of nearly 10,000 cases in 2003.

Only about one in five infected people get sick. Severe symptoms including neck stiffness, disorientation, coma and paralysis.

The state Health Department also reported that it found infected mosquitoes caught in traps placed in Hinds and Forrest Counties.

Rankin County has the highest number of reported cases this year at three. Scott County has had two reported cases.
