| - | The picture of the circulating influenza viruses in Quebec is currently produced every three months by MAPAQ. The classification used by MAPAQ laboratories is limited to the subtypes (H|N) of type A viruses. It is important to underline that the MAPAQ laboratory offers a free service to characterize the influenza virus subtypes circulating in Quebec pig population. For more details, see [[portrait_quebec_canada|Portrait des virus influenza (Options)]]. The work carried out by the MAPAQ laboratory shows that the following viruses are present in the pig population of Quebec: H1N1 and H3N2 are frequent; Pandemic | + | The picture of the circulating influenza viruses in Quebec is currently produced every three months by MAPAQ.

| In recent years, there have been several initiatives making it now possible to improve the classification of porcine influenza viruses by sequencing the HA gene (≈ 1700 bases). This methodology is prioritized by all the experts who work with the idea of developing commercial and autogenous vaccines better suited to the viruses circulating in pig populations. The proposed techniques classify the subtypes (H1) and the subtypes (H3).

| Vaccination for influenza is a technique of prevention and control of influenza recognized by all professionals of human health and various animal species. Scientific work and field observations all show the importance of homology between the strain (s) of virus integrated in the vaccine and those circulating in the target population. | Vaccination for influenza is a technique of prevention and control of influenza recognized by all professionals of human health and various animal species.

| Several veterinarians and pork producers in Quebec are interested in the development and rollout of autogenous vaccines that more specifically target strains circulating in Quebec farms because commercial vaccines are often ineffective because they do not contain the right strains. | Several veterinarians and pork producers in Quebec are interested in the development and rollout of autogenous vaccines that more specifically target strains circulating in Quebec farms because commercial vaccines are often ineffective because they do not contain the right strains. | ||
