Summary
Japanese health officials reported the second imported case of a laboratory-confirmed novel coronavirus from Wuhan, China Jan. 14. A 30-year old male developed a fever Jan. 3. He returned to Japan Jan. 6 from Wuhan City, China and on the same day he visited a health facility; he was hospitalized Jan. 10. The patient's symptoms have subsided and he was discharged Jan. 15. This is the most recent data as of Jan. 17.

Background and Analysis
This is the second exported novel coronavirus case from Wuhan City, China since the outbreak started Dec. 31, 2019. 41 cases were confirmed through Jan. 3, 2020. The patient's exposure history is currently under investigation. His history states he did not visit the Huanan South China Seafood Market where the majority of the cases were reported. Since the patient did not visit this market, investigations continue to identify the source of infection. No clear evidence is available of human-human transmission. Officials continue with active epidemiological investigations.

Advice
Emphasize basic health precautions, especially frequent handwashing with soap and water, or an alcohol-based hand sanitizer if soap and water are unavailable. Avoid close contact with animals (dead or alive). Practice good coughing and sneezing etiquette (maintain distance, cough and sneeze in a disposable tissue, wash hands). There is no evidence that influenza vaccine, antibiotics, or antiviral medications will prevent this disease, highlighting the importance of diligent basic health precautions.
