Pre-existing immunity to SARS-CoV-2 before the COVID-19 pandemic era in Cameroon: A comparative analysis according to HIV-status

Frontiers in Immunology, 2023
BackgroundThe lower burden of COVID-19 in tropical settings may be due to preexisting cross-immunity, which might vary according to geographical locations and potential exposure to other pathogens. We sought to assess the overall prevalence of SARS-CoV-2

Anal, penile, and oral high-risk HPV infections and HPV seropositivity in HIV-positive and HIV-negative men who have sex with men.

PLoS ONE, 2014
The effects of single or multiple concordant HPV infections at various anatomical sites on type-specific HPV seropositivity are currently unknown. In this cross-sectional study we assessed whether high-risk HPV infections at various anatomical sites (i.e.

Association of Patients’ Geographic Origins with Viral Hepatitis Co-infection Patterns, Spain

Emerging Infectious Diseases, 2011
To determine if hepatitis C virus seropositivity and active hepatitis B virus infection in HIV-positive patients vary with patients’ geographic origins, we studied co-infections in HIV-seropositive adults.

Decreased pre-existing Ad5 capsid and Ad35 neutralizing antibodies increase HIV-1 infection risk in the Step trial independent of vaccination. [PDF]

PLoS ONE, 2012
The Step trial raised the possibility that uncircumcised men with pre-existing Ad5 neutralizing antibodies carried an increased risk of HIV infection after vaccination. Thus, understanding Ad seropositivity in humans is important to the development of an
