The Ministry of Health of Brazil confirmed the first human case of West Nile Virus in the country on Dec. 9.

The case occurred in Piaui, a state within the borders of Brazil.

The patient first showed symptoms of West Nile Virus in August 2014. Health professionals immediately placed the patient under observation in a hospital in Teresina, Piaui.

Laboratory tests confirmed that the infection was West Nile Virus on Nov. 28.

Physicians recently cleared the patient for discharge from the hospital, although physical therapy and rehabilitation are required for the patient to fully recover from the disease.

Four other patients had symptoms of the virus, but tests have since ruled out West Nile Virus.

Health professionals tested 18 other people from Piaui for the virus. All of the patients tested negative for West Nile Virus.

West Nile Virus is transmitted to humans and other mammals through mosquitoes. The most common West Nile Virus symptoms include headaches, fevers, skin rashes, body aches and swollen lymph glands. Symptoms can grow more severe until they result in sleepiness, coma, disorientation, paralysis, stiff necks, tremors and convulsions.

Most West Nile cases are mild and are never reported.
