What You Should To Know About The H1n1 Bug

Read More About Health Care

All birds and mammals can be infected with a form of flu virus, of which there are three types (A, B and C). Humans can be infected by forms of all three, but most influenza varieties in animals and humans that cause serious health concerns are influenza Type A. Viruses can mutate rapidly, and because hosts' immune systems do not initially guard against new mutations, new strains can subsequently cause widespread infection. Often new strains result from the spread of an existing flu virus from one species to another, which provides the virus with the necessary tools to transmit between members of a different species to it's usual host.

Swine Flu

The latest flu strain to hit the headlines (H1N1) - known popularly as "H1n1" is a strain of influenza Type A. While the normal version of "Swine Flu" causes outbreaks of influenza with low mortality rates in pigs, the strain which is currently causing human deaths is not the same bug. The new strain combines genes from human, pig, and bird flu and is similar to the strain that caused "Spanish Flu", responsible for a human pandemic in 1918. "H1n1" is an entirely different virus to the "Bird Flu" which was widely talked about last year, and among the most important differences is that "Bird Flu" infected humans who had direct contact with infected birds, where as "Swine Flu" is being transmitted from human to human.

Flu in Horses

flu is widespread in horses and is believed to have a nearly 100% infection rate in unvaccinated populations. Influenza in horses is primarily caused by the H7N7 and H3N8 strains. In 2007, an outbreak caused the Sydney Races in Australia to be suspended.

Flu in Cats

An avian strain ( H5N1) of influenza Type A, which was given the popular name "Bird Flu", had until recently posed the greatest peril for a new influenza pandemic since it first killed people in Asia in the 1990s, but it did not mutate into a form that spreads easily between individuals. H5N1 is unusual in being deadly to many species, including domestic cats which were never before susceptible to any influenza virus. Aside from when infected with H5N1, the term "Feline Flu" does not actually refer to infection by influenza, but instead generally refers to the symptoms of an upper respiratory tract illness. Because cats have little contact to influenza viruses, any case of influenza which was able to transmit between people or dogs and cats would probably lead to a widespread infection, since cats have no natural immunity to any flu virus.

Flu in Dogs

Type A flu viruses also include equine influenza (H3N8), which in 2004 was discovered to be responsible for Canine flu. Because of the lack of previous contact to this bug, dogs have no natural immunity to this virus.

Flu in Pigs

Although this new flu is being called "H1n1," it is being spread from person to person, not from pigs to people. None of the infected people in North America have had contact with pigs, and no pigs in North America have been found to be infected with this strain. Pet pigs are therefore not known to be able to contract the strain of "Swine Flu" which is being talked about in the news, however they are able to contract normal "Swine Flu", which does not as a rule have any more serious consequences than seasonal flu does for people.

Conclusions

In general, flu viruses are not transmitted from one species to another. For example, dogs and cat do not develop influenza after exposure to owners with a seasonal flu bug. While it is theoretically possible for a new influenza strain to be transmissible between people and other domestic animals, it is likely that such a strain would be transmissible between only people and one other animal. Because the "H1n1" virus contains genetic elements of human, pig and avian flu viruses, it would seem very unlikely that this strain would have the ability to infect hosts which are not humans, pigs or birds. And, according to the American Veterinary Medicine Association (AVMA), "there is no proof that pets are susceptible to this new strain of flu; it appears to be transmitted solely from person to person".
