What causes animal influenza?
Bird flu occurs naturally in wild waterfowl and can spread into domestic poultry, such as chickens, turkeys, ducks and geese. The disease is transmitted via contact with an infected bird’s feces, or secretions from its nose, mouth or eyes.
How is influenza A transmitted to humans?
Person to Person
Most experts think that flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.
How is zoonotic influenza transmitted?
Zoonotic influenza occurs when humans are infected with influenza viruses circulating in animals. Human infections are primarily acquired through direct contact with infected animals or contaminated environments. This type of infection does not result in the efficient transmission of these viruses between humans.
Can animals pass the flu to humans?
While it is unusual for people to get influenza infections directly from animals, sporadic human infections and outbreaks caused by certain avian influenza A viruses have been reported.
Can you be around someone with the flu?
The flu is a very contagious virus. An infected person often becomes contagious, or capable of spreading the virus to other people, even before they begin to show symptoms. Also, it’s possible to spread flu germs to others for up to seven days after becoming ill.
Is it possible to catch influenza twice?
Yes, because the virus can mutate (change). If you become infected with the swine flu virus, your body produces antibodies against it, which will recognize and fight off the virus if the body ever meets it again.
Coronaviruses are a large family of viruses. Some coronaviruses cause cold-like illnesses in people, while others cause illness in certain types of animals, such as cattle, camels, and bats. Some coronaviruses, such as canine and feline coronaviruses, infect only animals and do not infect people.
Why is influenza A zoonotic virus?
Influenza A viruses (IAVs) possess a great zoonotic potential as they are able to infect different avian and mammalian animal hosts, from which they can be transmitted to humans.
How can zoonotic influenza be prevented?
Surveillance for zoonotic influenza virus therefore must be routinely conducted among agricultural workers. Also, use of personal protective equipment, frequent hand washing, and restrictions on smoking in or around swine facilities should be encouraged.
