Bird flu is caused by influenza A viruses. How does bird flu spread to humans? People catch bird flu by close contact with an animal’s fluids, such as saliva, respiratory droplets, or droppings (poop). You may breathe in small dust particles containing the virus in the animal’s habitat...
30 Continuous evolution of the H5N1 virus has been suggested by changes in the internal gene constellation, expanded host range, increased pathogenicity, and greater environmental stability.31, 32 Symptoms and signs According to one study, symptoms of H5N1 infection include typical influenza-like ...
Our findings suggest that although the infection rate of avian influenza A(H7N9) virus in patients with fever and flu-like symptoms is rare, the screening is valuable to rapidly define the infection, which will be critical to improve the clinical outcomes.Wu...
against swine strains of influenza (9). In this study we did not attempt to associate disease symptoms with exposure to wild waterfowl. Others have shown that domestic bird–acquired influenza A/H7N7 in humans may frequently lead to minor illness, such as con- ...
There are no pathognomonic signs and symptoms of A/H5N1 infections. The clinical, laboratory, and radiologic findings are not distinguishable from other causes of influenza-like illness, severe community acquired pneumonia, or ARDS. The only feature that raises the suspicion of avian influenza infect...
symptoms, with birds usually clearing the infection within a matter of days. Dabbling ducks (Anatinae) infected with highly pathogenic avian influenza virus (HPAIV) H5Nx subtypes, similar to LPAIV infection, can be minimally affected while shedding large quantities of virus, with mild disease ...
Typically, wild birds infected with low-pathogenic avian influenza A viruses are asymptomatic or display subclinical symptoms4, allowing the virus to be spread over long distances with host migration. During infection, AIVs preferentially localize in the intestinal tracts of migratory waterfowl and are...
To the Editor: The first avian influenza (H5N1) outbreak in poultry in Laos occurred in 2003 and subsided in March 2004 after massive killing of poultry to contain the disease. Extensive surveillance from July 2005 through January 2006 did not detect any influenza virus subtypes in chicken, duck...
