Herd immunity refers to a situation where a large portion of a population becomes immune to a disease, either through vaccination or previous infection, providing indirect protection to those who are not immune. When enough people in a community are immune to a disease, it becomes more difficult for the disease to spread from person to person. Herd immunity is important for protecting vulnerable individuals who cannot receive vaccines because of medical reasons or age, such as newborns or individuals with certain medical conditions. The level of immunity needed to achieve herd immunity depends on the contagiousness of the disease and varies from one disease to another.

Informed consent is when a person, usually a patient, agrees to undergo a medical procedure or treatment after receiving clear information about the procedure, its risks, benefits, and alternatives. It makes sure that individuals have the necessary information to make careful decisions about their healthcare. If a patient is unable to provide consent because of factors like being unconscious or having mental problems, someone else, such as a legal guardian or family member, may provide consent instead, following legal and ethical guidelines. Informed consent typically involves a discussion between the healthcare provider and the patient, where the provider explains the treatment, including potential risks and side effects, as well as any available alternatives. The patient then has the opportunity to ask questions and express concerns before agreeing to proceed with the treatment. Informed consent is a fundamental ethical principle in medicine and is legally required in many places to protect the rights of patients.

Computed tomography, commonly known as CT, is a medical imaging technique that uses X-rays and computer processing to create detailed images of the body. It allows healthcare providers to visualize internal structures such as bones, organs, and tissues in great detail, helping in the diagnosis and monitoring of various medical conditions. During a CT scan, the patient lies on a table that moves through a doughnut-shaped machine while X-ray beams rotate around the body. The resulting images provide valuable information about the size, shape, and density of the structures inside the body, helping healthcare professionals to identify abnormalities and plan appropriate treatment.
