On January 6th, before we even knew that China's pneumonia outbreak was due to an emerging coronavirus, the CDC Issued a Level 1 (Watch) Travel Notice For Unidentified Pneumonia - Wuhan, China.
Today, with cases spreading across China, the CDC has released a revised Travel Advisory advising enhanced precautions for travelers.
Novel Coronavirus in ChinaWarning - Level 3, Avoid Nonessential Travel
Alert - Level 2, Practice Enhanced PrecautionsWatch - Level 1, Practice Usual Precautions
Key PointsWhat is the current situation?
- There is an ongoing outbreak of pneumonia first identified in Wuhan, China, caused by a novel (new) coronavirus.
- Person-to-person spread is occurring, although it’s unclear how easily the virus spreads between people.
- Preliminary information suggests that older adults and people with underlying health conditions may be at increased risk for severe disease from this virus.
- Travelers to Wuhan, China, should avoid contact with sick people, animals (alive or dead), and animal markets.
- Travelers from Wuhan to the United States, and other countries, may be asked questions about their health and travel history upon arrival.
- The situation is evolving. This notice will be updated as more information becomes available.
A novel (new) coronavirus is causing an outbreak of pneumonia illness in the city of Wuhan, Hubei Province, China. This outbreak began in early December 2019 and continues to expand in scope and magnitude. Global surveillance is in the early stages and we expect more cases to be confirmed in China and beyond its borders. Signs and symptoms of this illness include fever, cough, and difficulty breathing. Initially some patients were linked to the Wuhan South China Seafood City (also called the South China Seafood Wholesale Market and the Hua Nan Seafood Market). However, since closing the market on January 1, 2020, more cases have been identified suggesting that some person-to-person spread is occurring though it’s unclear how easily this virus is spreading between people.
Coronaviruses are a large family of viruses. There are several known coronaviruses that infect people and usually only cause mild respiratory disease, such as the common cold. However, at least two previously identified coronaviruses have caused severe disease — severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV). SARS-CoV and MERS-CoV have been ruled out as the cause of the current outbreak.
Chinese health officials have reported hundreds of cases in the city of Wuhan and severe illness has been reported, including deaths. Cases have also been identified in travelers from Wuhan to other parts of China and other countries. This novel coronavirus has the potential to cause severe disease and death. Preliminary information suggests this is especially true among the elderly and those people with underlying health problems or compromised immune systems. Many characteristics of this novel coronavirus and how it may affect people are still unclear.
In response to this outbreak, Chinese officials have started exit screening for travelers leaving the city of Wuhan and several countries and territories in the region are reported to have implemented health screening of travelers arriving from Wuhan.
On arrival to the United States, travelers from Wuhan may undergo health screening, including having their temperature taken and filling out a symptom questionnaire.
Travelers with signs and symptoms of illness (fever, cough, or difficulty breathing) will have an additional health assessment.
