Beware of the Nile virus: the record year of 2018

MONTREAL – In Quebec, 2018 was a record year for cases of Western Nile virus, according to the latest data from the Ministry of Health.

With the 201 infected virus, which was transmitted last year by mosquito type, this is the peak since data is calculated in 2002. .

As far as what Quebecks are expecting this year, it remains to be seen. The National Institute of Public Health of Quebec (INSPQ) is not yet able to predict what damages will be done to mosquitoes in a given year, said science adviser Julie Ducrocq.

For example, the second highest maximum was recorded in 2012, with 134 cases. But next year, the fall was marked because it numbered only thirty people infected. The 2018 record can not predict a situation that will prevail in the summer of 2019.

In both cases, the region where most people are infected with the mosquito virus is Montérégie and then Montreal.

In Quebec, as elsewhere in Canada, the frequency of the West Nile virus is changing and can hardly be predicted from one year to the next, says the Ministry of Health of Quebec.

While most infected people have little or no symptoms, the consequences for others can be serious: of the 201 cases reported last year, 148 had a neurological procedure.

Most (84%) of clinical cases have been hospitalized, including almost one third (31%) in intensive care.

This data was collected by the Department of Public Health in the Department of Public Health of the Ministry of Health of Quebec, in collaboration with the National Institute of Public Health of Quebec.
