HIV: HIV infection is the world's most deadly epidemic. The HIV virus is transmitted through blood borne contact with an infected person. Many infected persons mistake symptoms for the flu or comparable viral-type infections. When a person has become infected with HIV, the body produces antibodies to the virus. For most people, these antibodies can be detected in a blood test by the time 2 to 12 weeks have passed since the exposure. In some cases, it can take up to 6 months. For this reason, it is very important to be aware that a negative (-) HIV test after a potential exposure may not mean an absence of HIV infection. This period of time between transmission of the HIV virus from one person to another and when the HIV can be detected by a blood test is called the "window period". buy now
Hepatitis C: HCV is a major cause of acute hepatitis and chronic liver disease, including cirrhosis and liver cancer. Globally, an estimated 170 million persons are chronically infected with HCV and 3 to 4 million persons are newly infected each year. HCV is spread primarily by direct contact with human blood. The major causes of HCV infection worldwide are use of unscreened blood transfusions, and re-use of needles and syringes that have not been adequately sterilized. buy now
