In mammals, including humans, A/H5N1 influenza (whether LPAI or HPAI) is rare. Symptoms of infection vary from mild to severe, including fever, diarrhea, and cough. [5] Human infections with A/H5N1 virus have been reported in 23 countries since 1997, resulting in severe pneumonia and death in about 50% of cases. [8]
Humans and other mammals can only become infected with avian influenza after prolonged close contact with infected birds. [7] In mammals including humans, infection with avian influenza (whether LPAI or HPAI) is rare. Symptoms of infection vary from mild to severe, including fever, diarrhea, and cough. [8]
In mammals including humans, infection with avian influenza (whether LPAI or HPAI) is rare. Symptoms of infection vary from mild to severe, including fever, diarrhoea, and cough. [29] As of February, 2024 there have been very few instances of human-to-human transmission, and each outbreak has been limited to a few people. [30]
But these are common bird flu symptoms in humans, according to the CDC: Eye redness (conjunctivitis) Mild flu-like upper respiratory symptoms. Pneumonia requiring hospitalization. Fever or feeling ...
Usually other differences also exist. Currently, there is no human-adapted form of H5N1 influenza, so all humans who have caught it so far have caught avian H5N1. Human flu symptoms usually include fever, cough, sore throat, muscle aches, conjunctivitis and, in severe cases, severe breathing problems and pneumonia that may be fatal.
It is a pathogen with strains that infect birds and some mammals, as well as causing seasonal flu in humans. [2] Mammals in which different strains of IAV circulate with sustained transmission are bats, pigs, horses and dogs; other mammals can occasionally become infected. [3] [4] IAV is an enveloped negative-sense RNA virus, with a segmented ...
Skin conditions in dogs are very common, so it's important to recognize the symptoms and understand the factors that cause them. Dr. Rebecca MacMillan, a vet with over 15 years of experience, says ...
While HPAI viruses have a very high mortality rate for chickens, [14] LPAI viruses are very mild and produce few, if any symptoms; outbreaks in a flock may go undetected without ongoing testing. [14] Wild ducks and other waterfowl are asymptomatic carriers of avian influenza, notably HPAI, and can be infected without showing signs of illness.
