Two more people have been stricken with the West Nile virus in Stanislaus County, the third and fourth cases reported this year by health officials.
The county Health Services Agency reported Friday that a 46-year-old woman was hospitalized with symptoms of the neuroinvasive form of the illness. The hospital was not identified and her condition was not given.
The second case was a 62-year-old man with West Nile fever, the less severe form of the illness spread by mosquito bites. Officials did not release the names of the victims or where they live.
In July, the HSA reported that a 78-year-old man was hospitalized with West Nile illness. His condition was unknown this week, as the agency does not keep track of the status of patients, a spokeswoman said.

The county has four of the 29 cases of West Nile illness recorded this year in California. Also in July, a 47-year-old Modesto-area woman tested positive with mild symptoms and was not hospitalized.
As of Friday, Los Angeles County, with 12, had the most cases.
Local mosquito abatement districts are continuing to test dead birds and mosquito samples to monitor the virus. On Monday, the Turlock Mosquito Abatement District will spray in and around Grayson, where a mosquito sample tested positive for West Nile this week.
Trucks will release the insecticide between 3 and 5:30 a.m. Residents are advised to stay indoors and keep windows closed during that time.
Health officials advised people to protect themselves from mosquito bites during the National Night Out activities scheduled Tuesday. Residents should apply insect repellant containing DEET, Picaridin or oil of lemon eucalyptus. Wear clothing to reduce skin exposure.
Mosquitoes are mostly likely to bite in the morning and evening.
