COVID-19 Daily Update February 21, 2020

Posted on Feb 21, 2020 in COVID-19

2/20/20 Marks Japan Visitor’s End Date of Infectious Period

February 20 was the last day that any individual who might have been infected by exposure to the visitor would be expected to show symptoms. At this time, there is no indication of transmission or related illness. The investigation has not yielded anyone who many have had prolonged, close contact with the visitor. Hawaii Department of Health (DOH) investigations remain ongoing into the visitor’s itinerary. Businesses have been contacted and informed.

Travel Advisories

On Feb. 20, the CDC announced travel advisories to Watch Level 1 for Japan and Hong Kong. Travelers are advised to practice usual precautions. For more info, visit:

On Feb. 20, the State Department updated their travel guidance and recommended U.S. citizens reconsider travel by cruise ship to or within East Asia and the Asia-Pacific Region.

The DOH is continuing to actively gather facts and interview individuals about a husband and wife who travelled together from Japan to Hawaii (Jan. 28-Feb.6) and after returning home to Japan, tested positive for COVID-19. DOH was notified by the Japan Ministry of Health that the husband remains hospitalized and the wife has recovered. The airlines and lodging facilities where they stayed on Oahu and Maui are reaching out to employees, staff and guests to keep them informed. DOH immediately began to identify possible close contacts and determine health risk.

To date, no individuals with prolonged close contact have been identified in Hawaii. Casual contacts who are not at risk have been interviewed and are not in need of monitoring based on current federal guidelines. All persons identified are either low or no risk under these guidelines, and no one is required to be monitored under public health supervision related to this situation. Work to track possible close contacts is ongoing, and DOH is working closely with state, federal, and international partners.

Cruise Ships

American passengers from the Diamond Princess cruise ship have been flown to bases in California and Texas for quarantine for 14 days. These actions are under federal authority and, at this time, the Department of Health does not have information on the passengers who are Hawaii residents.

The Department of Health has been notified of at least four Hawaii residents who were passengers on the Westerdam cruise ship (Holland America) and have returned home. DOH is in contact with these individuals and was advised that the cruise passengers are not at risk and do not pose a risk to others.

CDC Laboratory Test Kits

Currently, all laboratory testing to confirm COVID-19 is being conducted at the CDC laboratory in Atlanta, Georgia. The test kits sent to state laboratories, including Hawaii, had an issue with negative control primer probe sets included in each kit. New test kits are being developed by the CDC. It is estimated that Hawaii may receive test kits in early to mid-March. DOH has offered to be a beta-tester for the new kits to ensure they work properly. If Hawaii becomes a beta-tested, it means our state may have earlier access to the testing process.

Per CDC guidelines, testing is only conducted on individuals who meet the criteria as a Person of Interest (PUI), who exhibit symptoms of respiratory illness (cough or shortness of breath) and have traveled to China within the past 14 days. 

To date, there have been no samples sent to CDC from Hawaii since no individuals meet the CDC criteria.

No cases of COVID-19 identified in Hawaii at this time

Currently, there are no cases of COVID-19 identified in Hawaii. DOH is actively preparing for possible cases and working with state, county, and federal partners including the medical community in Hawaii. The following summary as of Feb. 21 shows the number of individuals being monitored or under quarantine because of their recent travel to China. These individuals were identified through screening by federal officials at the Daniel K. International Airport.
