It has been 2 months since the first case of coronavirus disease 2019 (COVID-19) was reported in Wuhan. So far, COVID-19 has affected 84,503 patients in 57 countries/territories and caused 2,924 deaths in nine countries. However, the epidemiology data differ across countries. Although China had higher morbidity and mortality than other sites, the number of new cases per day in China is lesser than that outside of China since February 26, 2020. The incidence ranged from 61.4 per 1,000,000 people in Republic of Korea to 0.0002 per 1,000,000 people in India. The daily cumulative index (DCI) of COVID-19 (cumulative cases/no. of days between the first reported case and February 29, 2020) was greatest in China (1,320.85 per day), followed by Republic of Korea (78.78 per day), Iran (43.11 per day), and Italy (30.62 per day). However, the DCI in other countries/territories were less than 10 per day. Several effective measures including restricting travel from China, controlling the distribution of masks, extensive investigation of COVID-19 spread, and at once daily press conference by government to inform and educate people were aggressively conducted in Taiwan. This is probably the reason why there was only 39 cases (as of February 29, 2020) with a DCI of 1 case per day in Taiwan, which was much lower than that of nearby countries, such as Republic of Korea and Japan. Additionally, the incidence and mortality were correlated with DCI. However, further study and continued monitoring are needed to better understand the underlying mechanism of COVID-19.

Termination of all transmission of infection by global extermination of the infectious agent through surveillance and containment (From Porta, A Dictionary of Epidemiology, 5th ed).
A species of CORONAVIRUS infecting cats of all ages and commonly found in catteries and zoos. Cats are often found carrying the virus but only a small proportion develop disease. Feline coronavirus and Feline infectious peritonitis virus (FIPV) are virtually the same virus in genetic and antigenetic terms, and are morphologically indistinguishable. Since they only differ in their disease potential (with FIPV causing a more serious illness), they are considered biotypes of each other.
A progressive form of dementia characterized by the global loss of language abilities and initial preservation of other cognitive functions. Fluent and nonfluent subtypes have been described. Eventually a pattern of global cognitive dysfunction, similar to ALZHEIMER DISEASE, emerges. Pathologically, there are no Alzheimer or PICK DISEASE like changes, however, spongiform changes of cortical layers II and III are present in the TEMPORAL LOBE and FRONTAL LOBE.

Field of medicine concerned with the determination of causes, incidence, and characteristic behavior of disease outbreaks affecting human populations. It includes the interrelationships of host, agent, and environment as related to the distribution and control of disease.
