Manitoba Agriculture and Resource Development reports a new case of a variant H1N2 (influenza A) flu virus.
This human influenza A(H1N2)v appears to be an isolated case. The current assessment is that there is no increased risk to Manitobans, Canadians or the food supply chain at this time.
The virus was detected in October after the individual independently sought testing after developing an influenza-like illness. The individual experienced mild symptoms, was tested and then recovered. The test came back negative for COVID-19, but was later identified as a case of human influenza A(H1N2)v through regular influenza surveillance processes.
The individual had direct exposure to pigs. Based on available evidence, the current assessment is that there is no increased risk to people, with no evidence of human-to-human transmission at this time.
This flu virus is related to influenza viruses that circulate in pigs. Influenza viruses from pigs do not normally infect humans. However, sporadic human infections with influenza viruses that normally circulate in pigs have occurred. When this happens, these viruses are called ‘variant viruses’.
The virus is not a food-related illness. It is not transmissible to people through pork meat or other products that come from pigs and there is no risk associated with eating pork.
Sporadic human cases of variant influenza have been reported over the past decade in North America. Human influenza A(H1N2)v is rarely seen in humans. One case was reported in Alberta in October 2020 and one in Manitoba in April 2021.
