- Current estimates of the incubation period of the virus range from 2-10 days, and these estimates will be refined as more data become available. Understanding the time when infected patients may transmit the virus to others is critical for control efforts. Detailed epidemiological information from more people infected is needed to determine the infectious period of 2019- nCoV, in particular whether transmission can occur from asymptomatic individuals or during the incubation period
- Among the 37 cases identified outside of China, three were detected without the onset of symptoms, while among the remaining 34 patients, there is information on date of symptom for 28 individuals.
- The median age of cases detected outside of China is 45 years ranging from2 to 74 years, 71% of cases were male (information was missing on age for 6 cases, and on sex for 4 cases).
- Of the 27 cases for whom we have detailed information on date of symptom onset and travel date from China, 8 cases had symptom onset in China, 5 had onset on the same day as travel, and 14 developed symptoms after leaving China.
- 36 cases had travel history to China, of whom 34 had travel history in Wuhan city, or had an epidemiological link to a confirmed case with travel history to Wuhan. For the remaining two, investigations into their travel histories are ongoing. One additional case was the result of human-to-human transmission among close family contacts in Viet Nam
- The basic principles to reduce the general risk of transmission of acute respiratory infections include the following:
• Avoiding close contact with people suffering from acute respiratory infections.
• Frequent hand-washing, especially after direct contact with ill people or their environment.
• Avoiding unprotected contact with farm or wild animals.
• People with symptoms of acute respiratory infection should practice cough etiquette (maintain distance, cover coughs and sneezes with disposable tissues or clothing, and wash hands).
• Within healthcare facilities, enhance standard infection prevention and control practices in hospitals, especially in
