Lymphocytic Choriomeningitis Virus from Pet Rodents

Rodents, such as mice, hamsters and guinea pigs, are popular as pets in many households. However, not all rodents that enter homes are intended as pets: some rodents are brought into homes as feed for other animals (e.g., pet snakes), and others, such as the house mouse, are pests that find their own way into homes.

Avian Flu in Birds is Spreading in Asia and Other Countries - An Overview

Avian influenza - commonly called "bird flu" - is an infection caused by influenza viruses that occur naturally in birds.

Wild birds can carry the viruses, but usually do not get sick from them. However, some domesticated birds, including chickens, ducks, and turkeys, can become infected, often fatally.

Avian Influenza A Viruses

Influenza viruses that infect birds are called avian influenza viruses. Only influenza A viruses infect birds, and all known subtypes of influenza A viruses can infect birds. However, there are substantial genetic differences between the subtypes that typically infect both people and birds. Within subtypes of avian influenza A viruses there also are different strains.

Spread of Avian Influenza Viruses among Birds

Avian influenza viruses circulate among birds worldwide. Certain birds, particularly water birds, act as hosts for influenza viruses by carrying the virus in their intestines and shedding it. Infected birds shed virus in saliva, nasal secretions, and feces.
