The pathogen causes coronavirus-19 disease (COVID-19), which spread rapidly, reaching the pandemic level on March 11, 20202. The incidence of cases and deaths caused by COVID-19 in the world increased at different rates from the first cases. In Brazil, a country of continental dimensions,...

Further reassortment with a Eurasian lineage of swine influenza virus resulted in the current pandemic influenza virus which has spread globally in humans 6 Host Range Influenza A virus is a zoonotic pathogen capable of infecting birds (waterfowl and chickens), swine, horses, felines, and other ...
While many people in the United States are growing comfortable living alongside COVID-19, the average number of daily deaths still runs at two to four times the long-term average for influenza, and it’s higher on a seasonally adjusted basis.5 Second, a new, immunity-evading variant could ...
Nevertheless, China has witnessed recurrent outbreaks of highly virulent EIDs including severe acute respiratory syndrome (SARS), highly pathogenic avian influenza (H5N1) and Streptococcus suis, a zoonotic bacterium mostly carried by pigs or pork products which causes syndromes of streptococcal toxic shock...
The fifth wave of H7N9 avian influenza virus caused a large number of human infections and a large number of poultry deaths in China. Since September 2017, mainland China has begun to vaccinate poultry with H5 + H7 avian influenza vaccine. We inves
Although influenza A and B are responsible for most human illness, influenza A causes the most serious disease because of a heightened capacity for “antigenic variability” compared with influenza B,25 a feature that allows the virus to escape, neutralizing antibodies produced by the human immune ...
The authors further found that the viral RNA coding sequence of 2019-nCoV spike protein, which forms the “crown” of the virus particle that recognizes the receptor on a host cell, indicates that the bat virus might have mutated before infecting people. How influenza jumped from animals ...
