Abstract. Some infections are more serious in pregnant than non-pregnant women because of the potential for vertical transmission to the fetus or infant (eg, varicella, rubella, cytomegalovirus infection, toxoplasmosis and listeriosis). Anyone can become infected with MRSA. However, people with open or uncleaned wounds or surgical sites are more likely to become infected.

In pathogenic simian immunodeficiency virus (SIV) and human immunodeficiency virus (HIV) infections, the translocation of microbial products from the gastrointestinal (GI) tract to portal and systemic circulation has been proposed as a major driver of the chronic immune activation that is associated with disease progression. Consistently, microbial translocation is not present in

CD4+ T Cells: Progressive depletion in numbers of circulating CD4+ T cells occurs in almost all cases of untreated HIV infection. The number of circulating CD4+ T cells is widely used as a measure of global "immune competence" and provides a predictor of the immediate risk for opportunistic illnesses. Earlier in the course of infection, many spread of infections such as blood-borne viruses (e.g., HBV, HCV, HIV) have prompted ongoing reassessment, update and improvement of IPAC practices. Infection prevention and control is an important part of safe patient care.

Treating STIs reduces prevalence and breaks the chain of transmission in the community, and is therefore the most effective form of prevention in the absence of a vaccine. However, facility-based case management alone is not enough to control STIs. infections such as pneumonia, septicemia, and endocarditis.5 • The risk of death in patients with MRSA has been found to be three times greater than with other hospital-acquired infections. 16
