Health authorities in Vietnam report two imported cases of 2019 Novel Coronavirus (2019-nCoV) Jan. 23 in individuals traveling to Vietnam Jan. 13 from Wuhan, China. Both individuals are hospitalized in isolation for treatment in Ho Chi Minh City. Contact tracing is underway, as these individuals traveled throughout Vietnam prior to displaying symptoms. Additional cases may be identified in other areas of the country.

Background and Analysis
Older individuals and those with chronic illness are more susceptible to infection and are at increased risk for severe complications. Human-to-human transmission has been confirmed by Chinese health authorities, though it remains unclear how easily the virus spreads between people. Some reports suggest conjunctivitis (reddening associated with infection or irritation of the eye) may be an early symptom of 2019-nCoV, and that respiratory droplets from infected individuals may infect others via contact with the mucous membrane of the eye. Investigations into transmission and disease modeling are ongoing. The reported clinical signs and symptoms of 2019-nCoV infection are primarily fever, chills, and difficulty breathing.

Emphasize basic health precautions, especially frequent handwashing with soap and water, or an alcohol-based hand sanitizer if soap and water are unavailable. Additionally, avoid close contact with animals (dead or alive), and practice good coughing/sneezing etiquette (i.e., covering coughs and sneezes with a disposable tissue, maintaining distance from others, and washing hands). There is no evidence that the influenza vaccine, antibiotics, or antiviral medications will prevent this disease, highlighting the importance of diligent basic health precautions.
