In the United States, a patient with influenza (flu), which is presumed to be caused by pigs, has occurred.
The World Health Organization (WHO) announced on the 11th (local time) that a case of human infection by the ‘novel influenza A strain (H1N2v) virus’ was reported from the US International Health Regulations (IHR) National Contact Center on the 4th (local time). (View original).
According to the WHO, the patient, a Michigan resident under the age of 18, went to the emergency room on the 29th of last month with symptoms including fever, cough, sore throat, muscle pain, headache, shortness of breath, diarrhea, nausea, dizziness and lethargy. A test the next day showed positive for the influenza A virus. Then, on the 2nd of this month, the final H1N2v infection was diagnosed in a detailed examination by the US Centers for Disease Control and Prevention (CDC).
The patient received antiviral treatment and was not hospitalized. You are recovering from an illness. A US investigation confirmed that the pigs were exposed at an agricultural fair between the 23rd and 29th of last month, prior to the onset of the disease.
So far (as of the 10th), there are no additional positive cases among the patient’s close contacts, family members, or people related to the agricultural fair. There is nothing suspicious about human-to-human transmission. Respiratory disease surveillance is underway for people who have attended fairs or have had recent contact with pigs.
This Michigan patient is the first case of H1N2v infection this year in the United States. In the United States, there have been 37 cases of human infection with the H1N2v virus since 2005. Total Influenza A strain virus infections (all subtypes) were 512 cases.
“Swine influenza A viruses circulate in pig populations in many parts of the world, and when an influenza A virus that normally circulates in pigs is isolated from humans, it is referred to as a ‘mutant’ influenza virus,” the WHO said. “There may be important antigenic and genetic differences between seasonal influenza viruses that circulate in pigs and influenza viruses that circulate in pigs, so close monitoring is needed to identify changes in the virus and human transmission early.”
