Transmission-based precautions are infection-control precautions in health care, in addition to the so-called "standard precautions". They are the latest routine infection prevention and control practices applied for patients who are known or suspected to be infected or colonized with infectious agents, including certain epidemiologically important pathogens, which require additional control ...
Acquired immune deficiency syndrome, or AIDS, is a communicable disease caused by the human immunodeficiency virus, HIV.AIDS is not curable. [citation needed] The first recognition of the emergence of an AIDS-like disease occurred in Los Angeles in 1981.
HIV-1 is the virus that was initially discovered and termed both lymphadenopathy associated virus (LAV) and human T-lymphotropic virus 3 (HTLV-III). HIV-1 is more virulent and more infective than HIV-2, [20] and is the cause of the majority of HIV infections globally. The lower infectivity of HIV-2, compared to HIV-1, implies that fewer of ...
Typhoid fever is an ailment caused by the bacterium Salmonella enterica ser. Typhi. An individual can acquire this infection from consuming risky foods or drinks, or by consuming foods or drinks prepared by an infected individual. Those who recover from this infection can still carry the bacteria in their cells, and therefore be asymptomatic. [16]
Hemophilia A causes a deficiency in Factor VIII, a protein required for blood clotting. Factor VIII injections are a common treatment to prevent or stop bleeding in people with hemophilia A. [1] Contamination of these and other products caused large numbers of hemophiliacs to become infected with HIV and hepatitis C.
HIV drug resistance poses an issue because it reduces the possible HIV medications a person can take due to cross resistance. In cross resistance, an entire class of medication is considered ineffective in lowering a patient's HIV viral load because all the drugs in a given class share the same mechanism of action. [7]
"The actions of this physician might have put patients at a low risk of exposure to possible infections, including hepatitis B and C and human immunodeficiency virus (HIV)," a Providence ...
The finding that superinfection occurs within and between HIV subtypes suggests that an immune response to initial HIV infection provide limited protection against infection by a new viral strain. [3] This means that HIV-vaccine strategies made to replicate the host's immune response to HIV infection may not prevent new infections. [3]
