AIDS virus, also known as HIV (Human Immunodeficiency Virus), is a single-stranded RNA virus. This virus belongs to the retrovirus family and has a genome composed of single-stranded RNA. When HIV enters a host cell, it uses the enzyme reverse transcriptase to convert its RNA genome into DNA. This DNA then integrates into the host cell’s genome, allowing the virus to replicate and spread within the body. HIV attacks the immune system, specifically targeting CD4 cells (T cells), which weakens the immune response and makes the body susceptible to opportunistic infections and certain cancers. As the virus progresses and the immune system becomes severely compromised, the condition known as Acquired Immunodeficiency Syndrome (AIDS) can develop. Effective antiretroviral therapy can control the virus and improve the quality of life for those living with HIV/AIDS.
AIDS is spread by physical contact [D] through the exchange of bodily fluids. The transmission routes include unprotected sexual intercourse, sharing needles or syringes, and from mother to child during childbirth or breastfeeding.

AIDS is spread by physical contact [D] through the exchange of bodily fluids. The transmission routes include unprotected sexual intercourse, sharing needles or syringes, and from mother to child during childbirth or breastfeeding. Additionally, blood transfusions with contaminated blood can spread HIV, which causes AIDS. Casual contact, such as shaking hands, hugging, or sharing food, does not transmit the virus. AIDS is not spread through respiratory contact like coughing or sneezing, nor is it transmitted by insects such as mosquitoes. Preventing the spread of HIV involves practicing safe sex, using clean needles, and ensuring safe blood transfusions. Public health initiatives aim to educate individuals on safe practices and provide testing and treatment to reduce the risk of transmission.
: A virus consists of nucleic acid and protein. The nucleic acid, which can be either DNA or RNA, contains the virus's genetic information. Surrounding the nucleic acid is a protein coat called a capsid, which protects the genetic material and aids in the virus's attachment to host cells. In some viRead more

Surrounding the nucleic acid is a protein coat called a capsid, which protects the genetic material and aids in the virus’s attachment to host cells. In some viruses, there may also be a lipid envelope derived from the host cell’s membrane that surrounds the capsid, providing an additional layer of protection. Carbohydrates are not a primary component of viruses, but they may be present as part of the lipid envelope in some cases. Therefore, the primary components of a virus are nucleic acid and protein.

SARS is a viral disease. It stands for Severe Acute Respiratory Syndrome, which is caused by the SARS coronavirus. This virus leads to serious respiratory illness in infected individuals, with symptoms such as fever, cough, and difficulty breathing. SARS was first identified in 2002 and caused an outbreak that spread to multiple countries. The disease can be severe and may result in pneumonia, acute respiratory distress syndrome, and sometimes death. Precautions such as quarantine, travel restrictions, and public health measures were implemented during the outbreak to control its spread. Scientists have since studied the virus to develop diagnostic tests, treatments, and potential vaccines.
Measles is caused by a virus. The measles virus is highly contagious and spreads through respiratory droplets when an infected person coughs or sneezes. Symptoms typically begin with a high fever, cough, runny nose, and inflamed eyes, followed by a red rash that usually starts on the face and spreadRead more
Measles is caused by a virus. The measles virus is highly contagious and spreads through respiratory droplets when an infected person coughs or sneezes. Symptoms typically begin with a high fever, cough, runny nose, and inflamed eyes, followed by a red rash that usually starts on the face and spreads to the rest of the body. Complications from measles can include pneumonia, encephalitis, and other serious health issues. Vaccination is the most effective way to prevent measles and its complications. The measles vaccine is often combined with mumps and rubella vaccines in the MMR vaccine, which is recommended for children and adults who have not been vaccinated.
