CDC recommends that travelers avoid all nonessential travel to Japan. Widespread ongoing transmission of a respiratory illness caused by a novel (new) coronavirus (COVID-19) has been reported in Japan. Widespread ongoing transmission means that people have been infected with the virus, but how or where they became infected is not known, and virus transmission is ongoing in many communities across a country or region.
Illness with this virus has ranged from mild to severe. Signs and symptoms of infection include fever, cough, and trouble breathing. This new coronavirus has caused severe disease and death in patients who developed pneumonia. Risk factors for severe illness are not yet clear, although older adults and people of any age with serious chronic medical conditions are at higher risk for severe illness.
