*** Blood donors are people who had no symptoms at the time of donating blood (people with symptoms are deferred from donating) through a blood collection agency, but whose blood tested positive when screened for the presence of West Nile virus. Since they do not meet the national case definition for WNV infection, they are not included in the total human case count.
‡ Not all animals testing positive are necessarily ill or symptomatic of WNV infection. Some specimens are tested only for surveillance purposes.
# Borough reported for human cases is determined by where the case patient resides and may not always reflect where the case patient was actually infected.
