Hepatitis B and C virus infection among HIV patients within the public and private healthcare systems in Chile: A cross-sectional serosurvey.

Background: Coinfections of HIV patients with hepatitis B virus (HBV) and hepatitis C virus (HCV) are mayor public health problems, contributing to the emerging burden of HIV-associated hepatic mortality.

Community acquired infections with methicillin resistant strains of Staphylococcus aureus (MRSA) infections have a more aggressive clinical course and involve mostly skin and lungs. These infections appear as outbreaks among prisoners, sportsmen, men having sex with men and military personnel. The higher aggressiveness of these strains is due to the production of several toxins, mainly Panton- Valentine leukocidine.
