Common Place for COVID‑19 Local Spreading: Observation from Thailand

COVID‑19 is a new global public health problem. Its origin is from the Republic of China and it already spread to more than 150 countries.[1] Historically, the disease investigation teams in China found that the disease might link to wildlife animals and the first commonplace of spreading the disease is Wuhan Seafood Market, which is the biggest center for selling meats of wildlife animals in Hubei, China.[1] At first, the disease is usually imported to a new country by infected immigrants. After that, the local transmission might occur and the transmission chain causes further causing a national wide outbreak. The characteristic of local spreading is interesting. The study on this issue is very useful for disease control and prevention planning.
