Although the H5 2.3.4.4b virus seems poorly optimized for infection or spread in humans, with fewer than 20 cases since 2016, influenza leaves no room for complacency. The sheer number of infected wild birds and poultry has caused spillover infections to occur in wild carnivores, marine mammals...
Influenza viruses are respiratory pathogens that affect humans and a broad range of animals, including birds, pigs, horses, dogs, cats, and marine mammals such as whales and seals. They cause major losses to poultry, pig, turkey, and the horse racing industry and constitute a serious concern ...
It has been shown by serological tests that these viruses may produce infection in man. In the course of field studies of arthropods, small mammals and birds in California and Oregon, several viruses have been isolated which may prove to be of importance as disease agents, that is, Modoc ...
birds,but also closely related to humans,have important public health significance.In this paper,the significance of pet birds in the spread of loemia,the host range of loemia,the epidemiological features of loemia and the public health significance of loemias are reviewed.Pet birds show a ...

These can sometimes be prevented by vaccines, such as the flu vaccine.An example of parasitic infection is malaria.Malaria is caused by parasites transmitted to humans by infected mosquitoes.Once inside the body, the parasites can be difficult to kill or control.And of course these ...

Emerging and reemerging diseases especially among infectious diseases in humans and animals including birds are a natural phenomenon. These diseases emerge for a various reasons such as mutations (genetic drift), recombination (genetic shift) and reassortment of genes which may be influenced by ...
According to estimates published in the journal Science in 2018, there are 1.7 million unknown viruses in mammals and birds, 540,000 to 850,000 of them with the capacity to infect humans. But above all, the expansion ofhumanactivities and increased interactions with wildlife increase the risk ...
caused by influenza a virus, which causes acute infectious diseases of humans, birds and livestock. Infection source: sick birds or virus birds, with a large number of eggs. 10, the full name of AIDS is "acquired immune deficiency syndrome", is made up of HIV (human immunodeficiency ...
