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.

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.

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

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.

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.

Generally the fragile nature of the virus prevents it from surviving for a substantial amount of time in the open air. The only studies on the survival of HIV outside the body have been conducted in the laboratory under controlled scientific conditions. These studies have found HIV is not affected by extreme cold, but it is destroyed by temperatures of 60 degrees centigrade and above.

HIV does not survive for very long outside of the human body. HIV is unable to reproduce outside its living host, except under laboratory conditions. Therefore, it does not spread or maintain infectiousness outside its host.

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.

Hepatitis A virus is spread from person to person by putting something in the mouth that has been contaminated with the stool of a person with hepatitis A. This type of transmission is called "fecal-oral." For this reason, the virus is more easily spread in areas where there are poor sanitary conditions or where good personal hygiene is not observed. Most infections result from contact with a household member or sex partner who has hepatitis A.

HAV can live outside the body for months, depending on the environmental conditions. HAV is killed by heating to 185 degrees F. (85 degrees C.) for one minute. However, HAV can still be spread from cooked food if it gets contaminated after cooking. Adequate chlorination of water, as recommended in the US, kills HAV that may get into the water supply.

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.

Hepatitis C is a virus that causes chronic inflammation of the liver and liver disease. About four to five million Americans have hepatitis C and more than 15,000 new cases develop each year.

Two products are used to prevent hepatitis A virus infection: immune globulin and hepatitis A vaccine. Immune globulin is a preparation of antibodies that can be given before exposure for short-term protection against hepatitis A and for persons who have already been exposed to hepatitis A virus. Immune globulin must be given within 2 weeks after exposure to hepatitis A virus for maximum protection.

Anyone can be infected with the hepatitis C virus. However, people most likely to be infected with the hepatitis C virus include individuals who: (1.) had a blood transfusion and or received an organ transplant such as kidney, lung, or heart, before effective screening began in July 1992; (2.) have been or are on long term kidney dialysis (hemodialysis); (3.) received treatment with a clotting factor concentrate manufactured before 1987; (4.) have ever injected illegal drugs, even once; (5.

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.

The duration that these viruses can survive in the environment depends on temperature and humidity conditions, but they may survive up to weeks in cooler and moister conditions. According to CDC and WHO, US NIOSH certified N-95, European CE certified EN143 P2 / EN149 FFP2, or comparable national/regional particulate respirators should be worn by workers who eradicate infected poultry. Higher level particulate respirators may also be used.
