What are the most common animal viruses?

It's tough to give a definitive "most common" list for animal viruses as prevalence varies drastically based on factors like:

* Animal species: Viruses specific to certain animals are obviously more common in those species.

* Geographic location: Virus spread is influenced by factors like climate and animal populations.

* Time of year: Certain viruses are more prevalent during specific seasons.

* Vaccination status: Vaccination significantly reduces the prevalence of some viruses.

However, some of the most frequently encountered animal viruses include:

For Domestic Animals:

* Canine distemper virus (CDV): Affects dogs.

* Feline leukemia virus (FeLV): Affects cats.

* Parvovirus: Affects dogs and cats.

* Rabies virus: Affects a wide range of mammals, including dogs, cats, raccoons, bats, and foxes.

* Bovine viral diarrhea virus (BVDV): Affects cattle.

* Porcine reproductive and respiratory syndrome virus (PRRSV): Affects pigs.

* Avian influenza virus (AIV): Affects poultry.

* Newcastle disease virus (NDV): Affects poultry.

* Foot-and-mouth disease virus (FMDV): Affects cattle, sheep, goats, and pigs.

For Wildlife:

* West Nile virus: Infects birds, mosquitoes, and mammals, including humans.

* Ebola virus: Affects primates and other mammals.

* Hantavirus: Infects rodents and can be transmitted to humans.

* Influenza A virus: Avian influenza strains can affect various bird species.

Important Notes:

* Emerging viruses: New viruses are constantly emerging and can become significant threats.

* Zoonotic viruses: Some viruses can be transmitted from animals to humans, posing public health risks.
