Outside of the animal's body, the rabies virus doesn't live very long. Sunlight rapidly destroys the virus. Inside of a dead animal's body, the rabies virus may live longer, depending on how far decomposed the animal's body is. Decomposition takes longer in cold weather.

In humans, symptoms usually develop after three to eight weeks. In some cases, symptoms have appeared as early as nine days and as long as seven years after exposure.

Rabies is a fatal virus infection, most commonly found in bats, raccoons, skunks and foxes. The infection is spread by the saliva; most commonly by a bite from an infected animal. Vaccinations are very effective for prevention.

This varies with the mosquito species and the time of the year. Some species may only live for less than a week, while others can live for several months over the winter months. (BACK)

Although HIV can survive outside the body for a few hours in certain bodily fluids, it cannot function when dry. The Virus cannot infect some one unless it enters the body.

The manufacturing process does not use a wild (i.e., naturally occurring) rabies virus, but rather an attenuated or weakened (also known as “fixed”) strain of virus called the Pitman-Moore vaccine strain. The attenuated vaccine strain has been tested in animal models and has been shown to be less infectious than wild rabies virus. The Pitman-Moore strain produces a protective immune response, which is why it is used to make the vaccine.

The smallpox virus is fragile. In laboratory experiments, 90% of aerosolized smallpox virus dies within 24 hours; in the presence of ultraviolet (UV) light, this percentage would be even greater. If an aerosol release of smallpox occurs, 90% of virus matter will be inactivated or dissipated in about 24 hours. (added Nov 13, 2002)

It is next to impossible for an opossum to carry the virus because of the genetics of the animal. Only in extreme cases will animal control test these animals.

Hepatitis A virus can live outside the body for months, depending on the environmental conditions. The virus is killed by heating to 185 degrees F (85 degrees C) for one minute. However, the virus can still be spread from cooked food if it is contaminated after cooking. Adequate chlorination of water, as recommended in the United States, kills hepatitis A virus that enters the water supply.

Although staph can live on surfaces for days to weeks, it doesn’t mean that it will make a person sick. Staph has to get off the surface and onto someone’s skin, where the organism may or may not survive due to the presence of competing organisms. Even if it survives on someone’s skin, it may simply live on the skin and not cause an infection. In order to cause an infection there has to be a break in the integrity of the skin.

Well I guess that depends on who you talk to--Most farmers who are in the egg producing business will say 2 years. Those who are in the meat producing business will say 6 months--Those who keep birds as pets (with names) or who are not interested in maximum production of eggs, will find that chickens can live up to 8 or 10 years.

It is not known how long it has been in the U.S., but the Center for Disease Control scientists believe the virus has probably been in the eastern U.S. since the early summer of 1999, possibly longer.

A.    While I probably would not test for this kind of information individually, it may well be a clue to the diagnosis of a specific disease. I would know it to be safe. Q.    What should we be focusing on in the supplemental readings? It seems as if many of the articles (mostly the AIDS articles) are very clincial. A.    I would try to understand the main points of each article, as well as to gain an appreciation of the details. A.

In very general terms, the larger a bird is, the longer its life expectancy. For small birds, such as migratory songbirds (warblers, vireos, etc.) the average life expectancy may be as little as two years. This short life expectancy is due to the many hazards birds face from birth: predators, disease, accidents, migration, starvation, habitat loss, and hunting, among others. Some individual birds have survived surprisingly long, including a cardinal (13.

The grains or plant live, with proper care as long as their owners. Kefir cultures reproduce themselves and do not know a physical death. We recommend making one litre (1½ pints) each time, though quantities of up to 2 litres is possible. Clean the Kefir grains daily by placing them in a sieve then allow medium flow of water to wash through the grains.

The average dog lives about 10-12 years. Unlike most animals, smaller breeds tend to live longer than larger ones.

The Human Immunodeficiency Virus is fragile. Once the virus is outside the body in a dry form, it dies immediately. Even in a wet state, it does not live long when exposed to heat, detergents, or disinfectants. When stored in blood banks at 4°C, it can live for about 3 weeks (or longer), or till the white cell disintegrates, but in a frozen state it can survive for years.

People usually get WNV from the bite of an infected mosquito. There is also evidence that WNV can be acquired via a blood transfusion or organ transplant from an infected donor.

Rabies is a virus that is in the saliva of an infected animal that works its way from the injury through the muscles to the nerves. Once it gets into the nerve, it travels to the spine and brain, finally causing death. It is a slow process, taking up to six months or longer.

Rabies can be spread from animal to animal, or animal to human. Rabies is spread when the saliva or brain tissue of an infected (rabid) animal gets in the mouth, the eyes, or an open cut. Rabies is most often spread to animals and humans through a bite from an infected animal.

Rabies is carried mainly by wild animals like raccoons, skunks, foxes, and bats. Humans, dogs, and cats can also get rabies. Squirrels, hamsters, guinea pigs, gerbils, chipmunks, rats, mice, and rabbits usually do not get rabies.

A rabies quarantine is a period of observation, either at home or at an approved location, where the animal suspected of being involved in a bite scratch, or exposure can be watched to determine if there is any danger of the animal transmitting the rabies virus. The quarantine period for most animals is 10 days from the date the exposure occurred.

It is usually found first in birds. Generally, surveillance by the Texas Department of Health finds the virus in birds a week or two before finding positive mosquitoes. The virus is in their bloodstream. Mosquitoes become infected when they feed on infected birds. The infected mosquitoes can then transmit West Nile Virus to humans and animals while biting to take blood.

Birds get it first. The virus is in their bloodstream. Mosquitoes become infected when they feed on infected birds. The infected mosquitoes can then transmit West Nile Virus to humans and animals while biting to take blood. The virus is located in their salivary glands and, during blood feeding, the virus can be injected into the animal or human, where it can multiply, possibly causing illness in the animal or human.

Rabies is a fatal disease which people can acquire through the bite, scratch or saliva of an infected animal. Because Rabies always causes death, our government has established laws pertaining to the vaccination of domestic animals, mainly dogs and cats. Even though we know that your pet’s Rabies protection does not expire on midnight of the day it is due, the law must make distinctions to protect people. In Sauk County, the first Rabies vaccination a pet receives is licensed for one year.

The Franklin County Boards of Health require that all dogs and cats be immunized against rabies by the time they reach three months of age. The rabies shot must be given by a licensed veterinarian.
