aerosol: (adj. aerosolized) A tiny solid or liquid particle suspended in air or as a gas. Aerosols can be natural, such as fog or gas from volcanic eruptions, or artificial, such as smoke from burning fossil fuels. <\/p>\n
antibodies: Any of a large number of proteins that the body produces from B cells and releases into the blood supplyas part of its immune response. Theproduction of antibodies is triggered whenthe body encounters an antigen, some foreign material. Antibodies then lock onto antigens as a first step in disabling the germs or other foreign substances that were the source of those antigens. <\/p>\n
commercial: An adjective for something that is ready for sale or already being sold. Commercial goods are those caught or produced for others, and not solely for personal consumption. <\/p>\n
coronavirus: A family of viruses named for the crown-like spikes on their surface (corona means crown in Latin). Coronaviruses cause the common cold. The family also includes viruses that cause far more serious infections, including SARS and COVID-19. <\/p>\n
COVID-19: A name given to the disease that erupted into a massive global pandemic in 2020. It first emerged in 2019 and is caused by a new coronavirus known as SARS-CoV-2. Symptoms can include pneumonia, trouble breathing, feeling too tired to walk more than a few steps, fever, headaches, low blood-oxygen levels, blood clots and brain fog. <\/p>\n
cyclone: A strong, rotating vortex, usually madeof wind. Natural examples includea tornado or hurricane. <\/p>\n
electricity: A flow of charge, usually from the movement of negatively charged particles, called electrons. <\/p>\n
electrode: A device that conducts electricity and is used to make contact with non-metal part of an electrical circuit, or that contacts something through which an electrical signal moves. (in electronics)Part of a semiconductor device (such as a transistor) that either releases or collects electronsor holes, or that can controltheir movement. <\/p>\n
electron: A negatively charged particle, usually found orbiting the outer regions of an atom; also, the carrier of electricity within solids. <\/p>\n
filter: (n.) Something that allows some materials to pass through but not others, based on their size or some other feature. (v.) The process of screening some things out on the basis of traits such as size, density, electric charge. (adj. filtration) <\/p>\n
flu: Short for influenza. A highly contagious viral infection of the respiratory passages causing fever and severe aching. It often occurs as an epidemic. <\/p>\n
HEPA: An acronym for high-efficiency particulate air. It's a term for a type of pleated air filter (usually made of cloth). It can theoretically remove at least 99.97 percent of airborne particles that are at least 0.3 microns in diameter. That includes most bacteria, dust, mold and pollen. Any particles that are larger or smaller may be trapped even more efficiently. Such filters are often used on vacuums, ventilation systems and as covers to protect the nose and mouth. <\/p>\n
immune system: The collection of cells and their responses that help the body fight off infections and deal with foreign substances that may provoke allergies. <\/p>\n
infection: A disease that can spread from one organism to another. Its usually caused by some type of microbe. <\/p>\n
link: A connection between two people or things. <\/p>\n
liquid: A material that flows freely but keeps a constant volume, like water or oil. <\/p>\n
nasal: Having to do with the nose. <\/p>\n
particle: A minute amount of something. <\/p>\n
PCR: An acronym for polymerase chain reaction. It's a biochemical process that repeatedly copies a particular sequence of DNA. <\/p>\n
protein: A compound made from one or more long chains of amino acids. Proteins are an essential part of all living organisms. They form the basis of living cells, muscle and tissues; they also do the work inside of cells. Antibodies, hemoglobin and enzymes are all examples of proteins. Medicines frequently work by latching onto proteins. <\/p>\n
SARS-CoV-2: A coronavirus that emerged in Wuhan, China, in late December 2019. It would go on to cause widespread and sometimes lethal disease throughout China and many other nations. Its name reflects its close similarity to the original coronavirus known as SARS (for severe acute respiratory syndrome). That SARS virus sparked a global outbreak of disease in 2003. <\/p>\n
system: A network of parts that together work to achieve some function. For instance, the blood, vessels and heart are primary components of the human body's circulatory system. Similarly, trains, platforms, tracks, roadway signals and overpasses are among the potential components of a nation's railway system. System can even be applied to the processes or ideas that are part of some method or ordered set of procedures for getting a task done. <\/p>\n
virus: Tiny infectious particles consisting of genetic material (RNA or DNA) surrounded by protein. Viruses can reproduce only by injecting their genetic material into the cells of living creatures. Although scientists frequently refer to viruses as live or dead, in fact many scientists argue that no virus is truly alive. It doesnt eat like animals do, or make its own food the way plants do. It must hijack the cellular machinery of a living cell in order to survive. <\/p>\n
voltage: A force associated with an electric current that is measured in units known as volts. Power companies use high voltage to move electric power over long distances. <\/p>\n
