Pulmonary tuberculosis is disease that involves the lung parenchyma, and is often infectious (i.e., contagious [determined by sputum smear examination for acid-fast bacilli and mycobacterial culture]). Laryngeal tuberculosis is rare but highly infectious. Because the emphasis for pre-immigration medical evaluation is on infectiousness, for the purpose of this document, pulmonary tuberculosis refers to both disease [...]

Feline leukemia, FeLV, is a virus-based disease in cats that can cause anemia and lymphoma, among other serious illnesses. The virus can also suppress the cat’s immune system, affecting his/her ability to fight off bacteria, viruses and fungi that contribute to other serious health problems.
The feline leukemia virus is spread through direct contact with an [...]

Feline leukemia virus (FeLV) is one of the most important viruses infecting cats. FeLV tends to become a persistent infection and depresses the immune system of cats. FeLV is an important cause of anemia in cats and can cause cancers of several types.
FeLV invades and replicates in various cells of the cat’s immune system and [...]

Feline immunodeficiency virus (FIV) was first discovered in 1986 in a California cattery where some cats appeared to have an illness similar to AIDS (acquired immunodeficiency syndrome) in people. Since then, FIV has been discovered in every country that has tested cats for its presence. It appears likely that FIV has been present in cats [...]

Because of the lack of sufficient high-quality evidence on the surgical management of mesothelioma, the Lung Cancer Disease Site Group opinion is that:
• The role of surgery in the management of malignant pleural mesothelioma cannot be precisely defined. Specifically, the lack of randomised controlled clinical trials makes it impossible to determine whether the use of [...]

Colon cancer is a life-threatening condition that affects thousands of people. Doctors usually recommend surgery for the removal of colon cancer. If your doctor recommends surgery, the decision whether or not to have this surgery is also yours. This reference summary will help you understand better the benefits and risks of the different colon operations. [...]

HIV cannot be transmitted as easily as the influenza virus. Compared to other viral diseases, the prevention of HIV infection is therefore easier. In rich countries, individuals who don.t want to be infected with HIV may protect themselves and avoid HIV infection. The same people will not be able to avoid the influenza virus of [...]

Tuberculosis (TB) has a long history. It was present before the beginning of recorded history and has left its mark on human creativity, music, art, and literature; and has influenced the advance of biomedical sciences and healthcare. Its causative agent, Mycobacterium tuberculosis, may have killed more persons than any other microbial pathogen (Daniel 2006).

Epidemics and Pandemics
Influenza is a serious respiratory illness which can be debilitating and cause complications that lead to hospitalisation and death, especially in the elderly. Every year, the global burden of influenza epidemics is believed to be 3.5 million cases of severe illness and 300,000.500,000 deaths. The risk of serious illness and death is highest [...]
