Human Anatomy and Physiology HS2211 - HIV/AIDS

HIV/AIDS The virus that causes AIDS is known as HIV, or human immunodeficiency virus. It can be transmitted by sexual contact, syringe sharing, or from mother to child during childbirth or breastfeeding. There has been extraordinary progress in the fight against AIDS cases and AIDS deaths. HIV is still one of the deadliest and most pliable diseases known to man. HIV targets the immune system by killing CD4+ T cells, a kind of white blood cell that is essential for infection defence. People with untreated HIV may become more susceptible to life- threatening illnesses which may eventually lead to death. Fever, headache, rash, and diarrhea, weight loss, persistent diarrhea, and skin cancer are some of clinical symptoms of the virus Nowadays, HIV-positive people can live long, healthy lives because of the powerful anti-HIV drugs. These prescribed medications, taken daily, known as antiretroviral therapy (ART), can reduce the amount of virus in the blood to a level so low that it cannot be detected by common testing when taken as directed. Question: What approaches has scientist taken to develop the HIV vaccine? Monkeypox The monkeypox virus belongs to the Orth poxvirus genus, which also includes the variola virus, vaccinia virus, and cowpox virus. Monkeypox is comparable to smallpox but far less dangerous. The virus was first detected in 1958 in two outbreaks of smallpox-like disease in monkeys In The virus is categorized as a category A pathogen, posing the greatest threat to national security and public health. Human-to-human transmission of monkeypox results from direct contact with body fluids, trauma, and contact with contaminated clothing Alternatively, animal-to-human transmission can be caused by bites or scratches. Pre -symptoms of monkeypox infection are fever, headache, body pain, malaise, and swollen lymph nodes. There is currently no available treatment for monkeypox virus infection. There are, however, antiviral drugs that can be used to treat smallpox and other illnesses that may benefit patients infected with monkeypox (National institute of allergy and infectious disease ,2022). Question: What medication has the NIAID approved to treat small pox? Influenza Influenza is a highly contagious respiratory infection caused by a variety of flu viruses that infect the nose, throat and lungs. Most individuals recover from the flu within two weeks, but some may develop serious consequences such as pneumonia. Pandemic influenza occurs when a novel flu virus strain emerges that can quickly spread from person to person and against which most individuals have no immunity. Seasonal influenza sickens millions of people each year, resulting in thousands of persons being hospitalized and thousands of flu- related deaths. Flu infection can be especially dangerous for young children, the elderly, and pregnant women. The NIAID is also prepared for a potential pandemic flu danger, as the virus may quickly transmit from person to person. Flu viruses of this type can infect millions of people worldwide (National institute of allergy and infectious disease ,2022). Question: What new method is NIAID using to treat and prevent influenza? Tuberculosis Tuberculosis (TB) is a contagious disease caused
