Once again, the West Nile Virus is rearing its ugly head, and a particularly concerning outbreak in Georgia has authorities struggling to get a handle on the situation. Georgia officials have confirmed almost 20 human cases of the mosquito-borne virus so far this year, leading to three deaths, and a news release from the Georgia Department of Public Health says that compares unfavorably with just seven cases all of last year and no deaths.

Out in California, the state’s Department of Public Health announced three confirmed deaths in the state due to West Nile Virus.

“West Nile virus can cause a deadly infection in humans, and the elderly are particularly susceptible,” said CDPH Director and State Health Officer Dr. Karen Smith, according to reports. “August and September are peak periods of West Nile virus transmission in the state so we urge everyone to take every possible precaution to protect themselves against mosquito bites.”

Symptoms of the disease include headache, muscle and joint aches, rash, and neck discomfort.
