Contagious: an adjective describing any disease that can be spread by direct contact with an infected person or with germs released by an infected person into the air, clothing, or environment. Such a disease is called contagious. Or it could be a thought or behavior that spreads from person to person.
COVID-19 (new coronavirus infection): The name given to the disease that developed into a major global pandemic in 2020. The disease first appeared in 2019 and is caused by a new coronavirus known as SARS-CoV-2. Symptoms include pneumonia, difficulty breathing, feeling too tired to walk more than a few steps, fever, headache, low blood oxygen levels, blood clots, and brain “fog.”
Develop: Appearing or produced naturally or through human intervention such as manufacturing. (In biology) The growth of an organism from conception to adulthood. They often change in chemistry, size, mental maturity, or sometimes even shape.
Developing world: A region with relatively little industry and a low standard of living compared to developed countries such as the United States, Germany, and Japan.
Epidemiologist: Like health detectives, these researchers try to link a particular disease to what might have caused it or caused its spread.
Influenza: Abbreviation for influenza. This is a highly contagious viral infection of the respiratory tract that causes fever and severe pain. It often occurs as an epidemic.
Germ: Single-celled microorganisms such as bacteria, fungal species, and virus particles. Some bacteria cause disease. Some promote health in more complex organisms, such as birds and mammals. However, the health effects of most bacteria are still unknown.
Immune system: A collection of cells and their reactions that help the body fight infections and deal with foreign substances that can cause allergies.
Get infected:(adjective. infectious) Spreading disease from one organism to another. This usually involves introducing some type of disease-causing bacteria into the individual.
Localized: An adjective that describes something that has a very localized impact. (Antonym: extensive or extensive)
Measles: A highly contagious disease that usually affects children. Symptoms include a characteristic rash all over the body, headache, runny nose, and cough. Some people also develop pink eye, swelling of the brain (which can cause brain damage), and pneumonia. Both complications can lead to death. Fortunately, since the mid-1960s, vaccines have appeared that dramatically reduce the risk of infection.
Outbreak: The sudden outbreak of a disease in a group of people or animals. The term may also be applied to the sudden occurrence of destructive natural phenomena such as earthquakes or tornadoes.
Pandemic: An outbreak of a disease that affects a large part of the world or a large part of the population.
Pediatrician: A doctor who works in the field of medicine related to the health of children, especially children.
Vaccine: (v. Vaccination) A biological mixture resembling the causative agent of a disease. It is given to help the body create immunity against certain diseases. The injections used to administer most vaccines are known as vaccinations.
Virus: A small infectious particle consisting of genetic material (RNA or DNA) surrounded by proteins. Viruses can only reproduce by injecting their genetic material into the cells of an organism. Scientists often refer to viruses as living or dead, but in reality, many scientists argue that there are no truly living viruses. They do not eat like animals or produce their own food like plants. To survive, they must hijack the cellular machinery of living cells.
