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]
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.
In December, a HPAI H5N1 subtype of clade 2.3.4.4b was found in a captive Asian black bear and in wild and captive birds in a wildlife park in France. [17] A human case of H5N1 was reported in the U.S. in April, "though this detection may have been the result of contamination of the nasal passages with the virus rather than actual infection."
Bird flu is a scary illness with a high mortality rate. But so far, infections in the U.S. have been relatively mild—until now. A patient in Louisiana has been hospitalized with a severe case of ...
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 ...
The loss of birds due to HPAI and culling in Vietnam led to an average loss of 2.3 months of production and US$69–108 for households where many have an income of $2 a day or less. [100] The loss of food security for vulnerable households can be seen in the stunting of children under five in Egypt.
Dr. Rebecca MacMillan, a vet with over 15 years of experience, says she regularly sees four skin conditions in particular: skin allergies, parasites, acute moist dermatitis, and endocrine disease.
Influenza C virus, like influenza B virus, is primarily found in humans, though it has been detected in pigs, feral dogs, dromedary camels, cattle, and dogs. [ 12 ] [ 23 ] Influenza C virus infection primarily affects children and is usually asymptomatic [ 1 ] [ 11 ] or has mild cold-like symptoms, though more severe symptoms such as ...
