State Laboratory Gears Up for Zika Testing

HONOLULU – The Hawaii State Department of Health (DOH) State Laboratories Division is taking an active role in national efforts to control the spread of Zika Virus. Hawaii’s State Laboratories recently provided confirmatory testing for samples from American Samoa and the Marshall Islands to support these U. S. Affiliated Pacific Island Jurisdictions in verifying disease outbreak activity.

“Hawaii is fortunate to have an experienced and capable public health laboratory that can serve our state with timely and quality testing under emergency conditions,” said Health Director Dr. Virginia Pressler. “That same capability is not available in many other areas of the Pacific, and providing lab support to these areas, when we can, is critical to controlling the spread of diseases and reducing the risk of introduction to Hawaii.”

“With Zika emerging in U.S. island territories of American Samoa, Puerto Rico, and the Virgin Islands, the nation is on alert,” said Dr. Thane Hancock, team leader for the U.S. Centers for Disease Control and Prevention (CDC) American Samoa Zika Response. “The timely response by the Hawaii Department of Health’s State Laboratories staff provided critical support for local disease investigations and for monitoring potentially exposed pregnant women.”

This month, DOH began using the CDC developed real-time reverse transcriptase (rRT) polymerase chain reaction (PCR) test for Zika virus. With this recently developed capability, DOH provided officials in American Samoa and the Republic of the Marshall Islands (Majuro), the first laboratory evidence of Zika transmission in these two U.S. affiliated jurisdictions.

“It’s always a balance to ensure our state needs are met first, but the staff here is more than willing to step up to support national efforts,” said State Laboratories Director Dr. Christian Whelen. “This work helps to better prepare us for potential issues that could arise in our state, and identifying and controlling outbreaks in the Pacific benefits all of us.”

While PCR is the best test during early onset of symptoms, testing for antibody to the viruses is preferred after about a week of illness. CDC is shipping antibody test materials to Hawaii so that the department’s State Laboratories Division can establish these capabilities over the next few weeks.

“The testing is very similar to the methodology our labs use for other RNA viruses such as Chikungunya, dengue, influenza, and measles,” added Whelen. “Our laboratory staff have been thoroughly trained to safely work with high risk specimens.”

DOH continues to work with the healthcare community, state, county, and federal officials to prepare for infectious diseases that threaten Hawaii and the Pacific. The State Laboratories Division administers a statewide laboratories program which conducts and regulates scientific analysis in support of environmental quality, health and safety, and infectious disease monitoring and control activities.
