Pre-exposure Prophylaxis
Pre-exposure prophylaxis (PrEP), is the use of medications to prevent the spread of disease in people who have not yet been exposed to a disease-causing agent. Vaccination is the most commonly used form of pre-exposure prophylaxis; other forms of pre-exposure prophylaxis generally involve drug treatment, known as chemoprophylaxis. Examples include taking medication to prevent infection by malaria or HIV. In particular, the term ''PrEP'' is now synonymous in popular usage with the use of pre-exposure prophylaxis for HIV prevention. In general, the use of pre-exposure prophylaxis requires balancing the risks of the treatment (e.g., side effects from a drug) to healthy individuals with the risk of the disease. It should be contrasted with post-exposure prophylaxis, which is used once the patient has already been exposed to the infectious agent. Use of pre-exposure medication against specific diseases Malaria The use of pre-exposure drug treatment to prevent malaria usin ...

Medications
Medication (also called medicament, medicine, pharmaceutical drug, medicinal product, medicinal drug or simply drug) is a drug used to medical diagnosis, diagnose, cure, treat, or preventive medicine, prevent disease. Drug therapy (pharmacotherapy) is an important part of the medicine, medical field and relies on the science of pharmacology for continual advancement and on pharmacy for appropriate management. Drugs are Drug class, classified in many ways. One of the key divisions is by level of controlled substance, control, which distinguishes prescription drugs (those that a pharmacist dispenses only on the medical prescription) from over-the-counter drugs (those that consumers can order for themselves). Medicines may be classified by mode of action, route of administration, biological system affected, or therapeutic effects. The World Health Organization keeps a list of essential medicines. Drug discovery and drug development are complex and expensive endeavors undertake ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Drug Injection
Drug injection is a method of introducing a drug into the bloodstream via a hollow hypodermic needle, which is pierced through the skin into the body (usually intravenously, but also at an intramuscular or subcutaneous, location). Intravenous therapy, a form of drug injection, is universally practiced in modernized medical care. , there were 13.2 million people worldwide who self-administered injection drugs outside of medical supervision, of which 22% are from developed countries. A wide variety of drugs are injected, often opioids: these may include legally prescribed medicines and medication such as morphine, as well as stronger compounds often favored in recreational drug use, which are often illegal. Although there are various methods of taking drugs, injection is favoured by some people as the full effects of the drug are experienced very quickly, typically in five to ten seconds. It also bypasses first-pass metabolism in the liver, resulting in higher bioavailability an ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Monoclonal Antibody
A monoclonal antibody (mAb, more rarely called moAb) is an antibody produced from a cell lineage made by cloning a unique white blood cell. All subsequent antibodies derived this way trace back to a unique parent cell. Monoclonal antibodies are identical and can thus have monovalent affinity, binding only to a particular epitope (the part of an antigen that is recognized by the antibody). In contrast, polyclonal antibodies are mixtures of antibodies derived from multiple plasma cell lineages which each bind to their particular target epitope. Artificial antibodies known as bispecific monoclonal antibodies can also be engineered which include two different antigen binding sites ( FABs) on the same antibody. It is possible to produce monoclonal antibodies that specifically bind to almost any suitable substance; they can then serve to detect or purify it. This capability has become an investigative tool in biochemistry, molecular biology, and medicine. Monoclonal antibod ...

COVID-19
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by the coronavirus SARS-CoV-2. In January 2020, the disease spread worldwide, resulting in the COVID-19 pandemic. The symptoms of COVID‑19 can vary but often include fever, fatigue, cough, breathing difficulties, anosmia, loss of smell, and ageusia, loss of taste. Symptoms may begin one to fourteen days incubation period, after exposure to the virus. At least a third of people who are infected asymptomatic, do not develop noticeable symptoms. Of those who develop symptoms noticeable enough to be classified as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, hypoxia (medical), hypoxia, or more than 50% lung involvement on imaging), and 5% develop critical symptoms (respiratory failure, shock (circulatory), shock, or organ dysfunction, multiorgan dysfunction). Older people have a higher risk of developing severe symptoms. Some complicati ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Serodiscordant
A serodiscordant relationship, also known as mixed-status, is one where one partner is infected by HIV and the other is not. This contrasts with seroconcordant relationships, in which both partners are of the same HIV status. Without effective prevention measures, serodiscordant relationships can significantly contribute to the spread of HIV/AIDS, with the risk varying based on the type and frequency of sexual activity and the viral load of the HIV-positive partner. Globally, an estimated 34 million people are living with HIV, with 68% residing in sub-Saharan Africa nations such as Lesotho and 50% of cases affecting women. In the United States, over 140,000 HIV-serodiscordant heterosexual couples are estimated, with 52% of HIV-positive women in a national study reporting serodiscordant partnerships. Similarly, in sub-Saharan Africa, 47% of HIV-positive women are in stable serodiscordant relationships. The World Health Organization reports that up to 50% of individuals living with ...
