AsymptomaticShowing no symptoms of disease. A person infected with the virus can be asymptomatic because they are in an early stage of infection and symptoms have not yet developed (“pre-symptomatic”), or they may not develop any symptoms at all during their infection.CCOVID-19The name of the disease caused by the novel coronavirus, SARS-CoV-2, and is short for “Coronavirus Disease 2019.” (Source: WHO)Case fatality rate (CFR)An estimate of the risk of mortality from a contagious disease. The CFR is calculated by dividing the number of deaths caused by a disease by the number of CASES of that disease in a given time period. The CFR is time and location-dependent, and many different factors can influence the CFR, such as speed of diagnosis of cases, health system capacity, age and other demographic characteristics, among others. For COVID-19, estimates of the CFR have varied; in China, CFR estimates by province have ranged from <1% to 5.8%. Sources: CDC/Lipsitch et. al./WHOClose contactA person who may be at risk of a contagious disease because of their proximity or exposure to a known case. Exact definition of close contact differs by disease; for COVID-19, the CDC DEFINES a close contact as anyone who has been within 6 feet of a person infected with the virus for a prolonged period of time, or has had direct contact with the infected person’s secretions. (Source: CDC)Community transmission/spreadInfections identified in a given geographic AREA without a history of travel elsewhere and no connection to a known case.Contact tracingThe process of identifying, assessing, and managing people who have been exposed to a contagious disease to prevent onward transmission. (Source: WHO)Cordon sanitaireA measure preventing anyone from leaving a defined geographic area, such as a community, region, or country infected by a disease to stop the spread of the disease.CoronavirusA family of viruses that cause illness ranging from the common cold to more severe diseases, such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). The novel coronavirus recently discovered has been named SARS-CoV-2 and it causes COVID-19. (Source: WHO)DDrive through testingIndividuals remain in their vehicles, and medical staff in protective gear come to administer the swab test and the swabs are sent to a laboratory for testing.Droplet transmission/spreadA mode of transmission for a contagious disease that involves relatively large, short-range (less than 6 feet) respiratory droplets produced by sneezing, coughing, or talking. (Source: CDC)EElective surgeriesProcedures that are considered non-urgent and non-essential. During periods of community transmission, CDC is recommending postponing elective procedures, surgeries, and non-urgent outpatient VISITS. (Source: CDC)EpidemicAn increase, OFTEN sudden, in the number of cases of a disease above what is normally expected in that population in that area. (Source: CDC)Essential activities
