virus

To eliminate a disease or a condition in an individual, or to fully restore health. A cure for HIV infection is one of the ultimate long-term goals of research today. It refers to a strategy or strategies that would eliminate HIV from a person’s body, or permanently control the virus and render it unable to cause disease. A ‘sterilising’ cure would completely eliminate the virus. A ‘functional’ cure would suppress HIV viral load, keeping it below the level of detection without the use of ART. The virus would not be eliminated from the body but would be effectively controlled and prevented from causing any illness.

The total elimination of a pathogen, such as a virus, from the body. Eradication can also refer to the complete elimination of a disease from the world.

The hepatitis A virus is transmitted through contaminated food and water, as well as human faeces. It can be passed on during sex, particularly rimming (oral-anal contact). Symptoms usually last less than two months, although they continue in some people for up to six months. Drug treatment is not needed. A vaccine is available to prevent hepatitis A.

The hepatitis B virus can be spread through sexual contact, sharing of contaminated needles and syringes, needlestick injuries and during childbirth. Hepatitis B infection may be either short-lived and rapidly cleared in less than six months by the immune system (acute infection) or lifelong (chronic). The infection can lead to serious illnesses such as cirrhosis and liver cancer. A vaccine is available to prevent the infection.

The hepatitis C virus can be spread through sharing contaminated needles, syringes and other equipment to inject drugs, sharing straws to snort drugs, needlestick injuries, and during childbirth. Sexual transmission does occur, primarily between gay men. Hepatitis C can range from a mild illness lasting a few weeks to a serious, lifelong illness. Untreated chronic hepatitis C can cause serious liver damage, cirrhosis, liver cancer, and even death. While there is no vaccine, treatments are available to clear the virus from the body, leading to its cure.
