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.

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.

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.

No sooner the body fluid containing the HIV virus starts to dry, 90% to 99% of the virus present becomes disabled upon drying. HIV does not survive very long outside the body.

Some research suggests that the virus can remain active in dried blood for up to 2 months. More recent research (with chimpanzee blood) has found that the virus will remain active for at between 16 hours and 4 days.

Sperm can live in a woman's body for 5 sometimes 7 days, therefore a woman can get pregnant if she has sex up to 5 sometimes 7 days before ovulation.

Nicotine is processed very quickly- it will exit your body within a day of its consumption. However, this rapid metabolism also causes nicotine withdrawal symptoms to start the day you quit. Fortunately, these symptoms can be controlled with nicotine replacement therapy or will resolve on their own within a week.

Recent studies have shown that HCV can survive outside the body and still transmit infection for 16 hours, but not longer than 4 days.

There is no scientific evidence indicating that people can be chronically infected with West Nile virus. What remain in a person’s body for long periods of time are antibodies and “memory” white blood cells (T-lymphocytes) that the body produces to fight the virus. These antibodies and T-lymphocytes last for years, and may last for the rest of a person’s life. Antibodies are what many diagnostic tests look for when clinical laboratory testing is performed.

Recent studies suggest that HCV may survive on environmental surfaces at room temperature at least 16 hours, but no longer than 4 days.

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)

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.

Who is a carrier of hepatitis B virus? Sometimes, people who are infected with HBV never recover fully from the infection; they carry the virus and can infect others for the rest of their lives. In the United States, about one million people carry HBV.

Apart from the constant need for blood, regular blood donations are needed because blood has a short storage life. Whole blood and red cells can be stored for up to 21 – 42 days depending on the anticoagulant-preservative used. On the other hand, platelets only last from 3-5 days and fresh frozen plasma can be kept for 12 months.

Scientists and medical authorities agree that HIV does not survive well outside the body, making the possibility of environmental transmission remote. Whilst HIV is found in varying concentrations or amounts in blood, semen, vaginal fluid, breast milk, saliva, and tears, to obtain data on the survival of HIV, laboratory studies have required the use of artificially high concentrations of laboratory-grown virus.

If the blood is dry, the virus will be dead. If it is wet, a chance exists that it could still be active. The risk is very small, but rather be safe. Always try and use gloves when you are in a situation where you might be in contact with blood. HIV is very short lived on an inanimate surface. In wet fluid, consider infectious.

Research shows that liquid zeolite stays in the body about five to seven hours before it is 100% eliminated. This is why directions state that it should be taken three or four times a day, in order to maintain adequate levels in the body.

HIV can take up to six months to be detectable. Your body needs time to respond to the virus, and therefore the virus may not be detected till months after the actual transmission.

The virus lives only in the skin and once the growths are gone, the virus is gone and you cannot spread the virus to others. Molluscum contagiosum is not like herpes viruses, which can remain dormant (“sleeping”) in your body for long periods and then reappear. So, assuming you do not come in contact with another infected person, once all the molluscum contagiosum bumps go away, you will not develop any new bumps.

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)

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.

On the average, fourteen to fifteen years, with some passing sooner and a few lasting into their late teens and early twenties. BACK TO TOP

Generally, a small breed dog will outlive a large breed dog. The average lifespan for a poodle is somewhere around 15 years. We've had customers tell us their poodles lived into their 20s. This includes teacups.

Yes, infected persons develop immunity whether they develop symptoms or not. This is thought to be a life long immunity.

In the summer they could, but they could pick up parasites from the snails that live here in the UK and die. You must never, ever release Giant African Land Snails into the wild. They would not survive our climate; they would freeze to death in the winter, they have no immunity to diseases that are carried by our native snails, and in places they would have trouble finding enough food.

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.
