The first human case of the West Nile virus has been confirmed in Toronto.
Public health officials of Toronto did not give any further details, except that the laboratory-suggestion case is in an adult.
It is discovered less than two weeks after the public health agency confirming the presence of the virus in the city on 18 July.
Last year, the first human case of the virus was not confirmed until 16 August.
The West Nile Virus is a mosquito -borne disease that can be transmitted to humans through an infected mosquito bite. While most people do not experience mild or any symptoms, the virus can cause serious illness in some cases, especially in older adults or people with weak immune systems.
Symptoms usually develop between two to 14 days after cutting from an infected mosquito and may include fever, headache, nausea, vomiting, body pain, skin rash and inflamed lymph nodes.
