Anyone who thinks he or she is infected, or who is involved in high-risk behaviors, should not donate his/her blood, organs or tissues as they may now contain the AIDS virus
Although the hepatitis A virus can cause prolonged illness up to 6 months, it typically only causes short-lived illnesses and it does not cause chronic liver disease
Caused by the hepatitis B virus (HBV), can cause a wide spectrum of symptoms ranging from general malaise to chronic liver disease that can lead to liver cancer, spreads through infected body fluids such as blood, saliva, vaginal fluid, tear and urine
Caused by the hepatitis C virus (HCV), spread by direct contact with an infected person's blood, can lead to chronic liver disease and is the leading reason for liver transplant, can spread by sharing drug needles, getting a tattoo or body piercing with unsterile tools, blood transfusions, transmission from mother to newborn and sexual contact
Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV)
Hepatitis B can sometimes be treated using medications, and the treatment has improved significantly with the use of two medications, only one of which is approved for use in children
In those adults who have just been infected with hepatitis C (by accidental needle injury, for example), combination therapy with two drugs is the treatment of choice and can eliminate the virus in about 50% of people infected
An infection that can spread from person to person through direct contact, there are two types: HSV-1 primarily causes oral herpes, and HSV-2 primarily causes genital herpes
A highly infectious viral disease that mainly affects young children, caused by infection with the poliovirus, spreads through direct person-to-person contact, by contact with infected mucus or phlegm from the nose or mouth, or by contact with infected faeces
In paralytic polio, the virus leaves the intestinal tract and enters the bloodstream, attacking the nerves, resulting in muscle paralysis that can even result in death
