“Most infected people have no symptoms. Nevertheless. However, but about 20% can develop a severe form of encephalitis that can be fatal,” said epidemiologist Miarisoa Randra Rakotoarinia, from the Zoonoses team to the National Public Health Institute of Quebec.
She highlights the importance of protecting herself from Maringouin’s bites while construction holidays are in full swing by eliminating. stagnant waters around the house. Similarly, closing the mosquito nets and using mosquito repellents during outings outside. Moreover, “There is no vaccine or medication against the disease when it is declared,” she said.

Cycles
This disease tends to progress in cycles. that is to say that it does not experience continuous and gradual growth. This cycle is influenced by the immunity of birds, which are the guests of the virus. After a year with many cases, birds develop immunity, which reduces transmission the following year.
In addition to the rainy spring, high summer temperatures accelerate the spread of mosquitoes and the replication of the virus. Corvids are the favorite hosts and humans (as well as the horse) are only accidental targets. This means that the viral load is not high enough to contaminate other individuals.
