Mississippi health officials say a fourth person has died related to complications from the West Nile virus infection of the 2007 season.

The state Department of Health said the patient, a Lamar County resident, died in January. The case had been previously reported in 2007 as testing positive for the virus.

The agency also reported one additional human case of the virus in Harrison County in 2007, bringing Mississippi's total number of cases for the year to 134.

State health officer, Dr. Ed Thompson, said it is important to remember that mosquitoes are always active in the state and continue to bite and transmit the virus to humans.
