Timothy Edward Alexander Peto is a professor of medicine at the University of Oxford. He is the co-leader for the Infection Theme of the Oxford Biomedical Research Centre, [1] and a National Institute for Health and Care Research Senior Investigator. [2]
Peto's research has included combination therapy for AIDS, [3] the search for an effective AIDS vaccine, [4] the transmission of methicillin-resistant Staphylococcus aureus in hospitals, [5] and transmission mechanisms for Clostridioides difficile infections. [6]
Safe sex is sexual activity using methods or contraceptive devices to reduce the risk of transmitting or acquiring sexually transmitted infections (STIs), especially HIV. "Safe sex" is also sometimes referred to as safer sex or protected sex to indicate that some safe sex practices do not eliminate STI risks. It is also sometimes used colloquially to describe methods aimed at preventing pregnancy that may or may not also lower STI risks.
Norovirus, also known as Norwalk virus and sometimes referred to as the winter vomiting disease, is the most common cause of gastroenteritis. Infection is characterized by non-bloody diarrhea, vomiting, and stomach pain. Fever or headaches may also occur. Symptoms usually develop 12 to 48 hours after being exposed, and recovery typically occurs within one to three days. Complications are uncommon, but may include dehydration, especially in the young, the old, and those with other health problems.
The management of HIV/AIDS normally includes the use of multiple antiretroviral drugs as a strategy to control HIV infection. There are several classes of antiretroviral agents that act on different stages of the HIV life-cycle. The use of multiple drugs that act on different viral targets is known as highly active antiretroviral therapy (HAART). HAART decreases the patient's total burden of HIV, maintains function of the immune system, and prevents opportunistic infections that often lead to death. HAART also prevents the transmission of HIV between serodiscordant same-sex and opposite-sex partners so long as the HIV-positive partner maintains an undetectable viral load.
Charles Jules Henri Nicolle was a French bacteriologist who received the Nobel Prize in Medicine for his identification of lice as the transmitter of epidemic typhus.
Post-exposure prophylaxis, also known as post-exposure prevention (PEP), is any preventive medical treatment started after exposure to a pathogen in order to prevent the infection from occurring.
The National Institute of Allergy and Infectious Diseases is one of the 27 institutes and centers that make up the National Institutes of Health (NIH), an agency of the United States Department of Health and Human Services (HHS). NIAID's mission is to conduct basic and applied research to better understand, treat, and prevent infectious, immunologic, and allergic diseases.
The Division of Acquired Immunodeficiency Syndrome (DAIDS) is a division of the National Institute of Allergy and Infectious Diseases, which is part of the National Institutes of Health. It was formed in 1986 as a part of the initiative to address the national research needs created by the advent and spread of the HIV/AIDS epidemic. Specifically, the Division's mission is to increase basic knowledge of the pathogenesis, natural history, and transmission of HIV disease and to support research that promotes progress in its detection, treatment, and prevention. DAIDS accomplishes this through planning, implementing, managing, and evaluating programs in (1) fundamental basic research, (2) discovery and development of therapies for HIV infection and its complications, and (3) discovery and development of vaccines and other prevention strategies.
The human immunodeficiency virus (HIV) is a retrovirus that attacks the immune system. It is a preventable disease. There is no vaccine or cure for HIV. It can be managed with treatment and become a manageable chronic health condition. While there is no cure or vaccine, antiretroviral treatment can slow the course of the disease and enable people living with HIV to lead long and healthy lives. An HIV-positive person on treatment can expect to live a normal life, and die with the virus, not of it. Effective treatment for HIV-positive people involves a life-long regimen of medicine to suppress the virus, making the viral load undetectable. Without treatment it can lead to a spectrum of conditions including acquired immunodeficiency syndrome (AIDS).
Malaria vaccines are vaccines that prevent malaria, a mosquito-borne infectious disease which affected an estimated 249 million people globally in 85 malaria endemic countries and areas and caused 608,000 deaths in 2022. The first approved vaccine for malaria is RTS,S, known by the brand name Mosquirix. As of April 2023, the vaccine has been given to 1.5 million children living in areas with moderate-to-high malaria transmission. It requires at least three doses in infants by age 2, and a fourth dose extends the protection for another 1–2 years. The vaccine reduces hospital admissions from severe malaria by around 30%.
Robert Ray Redfield Jr. is an American virologist who served as the Director of the U.S. Centers for Disease Control and Prevention and the Administrator of the Agency for Toxic Substances and Disease Registry from 2018 to 2021.
Gladstone Institutes is an American independent, non-profit biomedical research organization whose focus is to better understand, prevent, treat and cure cardiovascular, viral and neurological conditions such as heart failure, HIV/AIDS and Alzheimer's disease. Its researchers study these diseases using techniques of basic and translational science. Another focus at Gladstone is building on the development of induced pluripotent stem cell technology by one of its investigators, 2012 Nobel Laureate Shinya Yamanaka, to improve drug discovery, personalized medicine and tissue regeneration.
HIV prevention refers to practices that aim to prevent the spread of the human immunodeficiency virus (HIV). HIV prevention practices may be undertaken by individuals to protect their own health and the health of those in their community, or may be instituted by governments and community-based organizations as public health policies.
Arthur J. Ammann was an American pediatric immunologist and advocate known for his research on HIV transmission, discovering in utero transmission and the risk of contaminated transfusions and blood products, and his role in the development of the first successful vaccine to prevent pneumococcal infection in 1977. He founded Global Strategies for HIV Prevention and was Clinical Professor of Pediatrics at the UCSF Medical Center.
Robert Palmer Beasley was an American physician, public health educator and epidemiologist whose work on hepatitis B involved extensive investigations in Taiwan. That work established that hepatitis B virus (HBV) is a primary cause of liver cancer and that hepatitis B virus is transmitted from mother to infant during childbirth. Beasley and his colleagues also proved that HBV mother-to-infant transmission is preventable by at-birth vaccination. Due to this work, the World Health Assembly designated HBV as the seventh global vaccine in 1992. He later became the author of HBV immunization policies for the World Health Organization.
HIV/AIDS research includes all medical research that attempts to prevent, treat, or cure HIV/AIDS, as well as fundamental research about the nature of HIV as an infectious agent and AIDS as the disease caused by HIV.
HIV in pregnancy is the presence of an HIV/AIDS infection in a woman while she is pregnant. There is a risk of HIV transmission from mother to child in three primary situations: pregnancy, childbirth, and while breastfeeding. This topic is important because the risk of viral transmission can be significantly reduced with appropriate medical intervention, and without treatment HIV/AIDS can cause significant illness and death in both the mother and child. This is exemplified by data from The Centers for Disease Control (CDC): In the United States and Puerto Rico between the years of 2014–2017, where prenatal care is generally accessible, there were 10,257 infants in the United States and Puerto Rico who were exposed to a maternal HIV infection in utero who did not become infected and 244 exposed infants who did become infected.
Lauren V. Wood is an American allergist, immunologist, and staff physician at the National Cancer Institute (NCI) at the National Institutes of Health (NIH) in Bethesda, Maryland, where she has served as a principal investigator. She is known for conducting studies of vaccines for cancer, Human papillomavirus (HPV), Hepatitis C, and HIV especially for use with children, teens and young adults. She holds the rank of captain in the U.S. Public Health Service (PHS).
Bruce D. Walker is an American physician and scientist whose infectious disease research has produced many findings regarding HIV/AIDS. He became interested in studying HIV/AIDS after practicing on the front lines of the epidemic in the early 1980s, prior to the identification of HIV as the etiologic agent and prior to the availability of viable treatment options.
Roy D. Mugerwa was a Ugandan physician, cardiologist and researcher. His contribution to the world of academics include being a Professor Emeritus at Makerere University College of Health Sciences in Kampala, cardiology in Uganda, researching HIV/AIDS and tuberculosis, and his efforts to find an effective HIV vaccine.
Allison Joan McGeer is a Canadian infectious disease specialist in the Sinai Health System, and a professor in the Department of Laboratory Medicine and Pathobiology at the University of Toronto. She also appointed at the Dalla Lana School of Public Health and a Senior Clinician Scientist at the Lunenfeld-Tanenbaum Research Institute, and is a partner of the National Collaborating Centre for Infectious Diseases. McGeer has led investigations into the severe acute respiratory syndrome outbreak in Toronto and worked alongside Donald Low. During the COVID-19 pandemic, McGeer has studied how SARS-CoV-2 survives in the air and has served on several provincial committees advising aspects of the Government of Ontario's pandemic response.
