Territory Sees 33 New Cases Of Zika As Virus Shows Signs Of Slowing

The U.S. Virgin Islands saw 33 new cases of the Zika virus this week, a marked decrease from last week’s 100 surge, although the Department of Health’s director of public relations, Nicole Tyson, said the latter number was a result of cases that were backlogged.

“The significant increase in positive cases is primarily due to pending results dating back three weeks; the case increase is not specific to last week,” Ms. Tyson. “As last weeks surveillance report indicated, there were a large number of pending results (261 on last report) that we received results back for and have updated the status in the database accordingly. The currently pending results reflects the most recent samples sent to CDC.”

This week’s total is 866, with St. Thomas leading with 570 confirmed cases, followed by St. Croix with 147 confirmed cases, and St. John with 63 confirmed cases. Pregnant women, which D.O.H. is now counting separately, stayed unchanged at 86 cases.

On Friday, the World Health Organization lifted the emergency status that it placed on the Zika virus on February 1, a sign that the mosquito-borne disease’s effect on the world had diminished. But the organization, a specialized agency of the United Nations, was quick to stress that the lifting of emergency status does not mean that it’s downgrading the virus, which has spread throughout Latin America, the Caribbean and even some U.S. mainland states. W.H.O. said Zika remains a long-term threat that must see an equally long-term strategy to fight it.

According to the Associated Press (via the New York Times), nearly 30 countries have reported birth defects linked to Zika, with over 2,100 cases of nervous-system malformations reported in Brazil alone.

W.H.O. said the public emergency was declared when Zika clusters were appearing and a sharp increase in research was needed. Also taken into consideration at the time, was the looming 2016 Rio Olympic Games. The February declaration led the world to an “urgent and coordinated response,” W.H.O. says.

Yet, the disease continues to spread, and W.H.O. acknowledged “many aspects of this disease and associated consequences still remain to be understood, but this can best be done through sustained research.”

“It is a significant and enduring public health challenge, but it no longer represents an emergency,” Dr. David Heymann, who heads the W.H.O. emergency committee on Zika, said (via A.P.) after the panel met for the fifth time this year. “There was no downgrading of this.”

Dr. Heymann said recommendations made in recent months were now being “internalized” W.H.O., which is based in Geneva.

“If anything, this has been escalated in importance by becoming activities that will be continued in the long-term in the World Health Organization,” he said.

According to the A.P., W.H.O.’s emergency declarations are traditionally designed to motivate governments to take steps to curb epidemics. “But Zika has traveled quite far by now. It’s not quite clear to me what the impact” of continuing the declaration would be, Stephen Morse, an infectious disease expert at New York City’s Columbia University, said.

Zika is spread primarily through the bite of an infected Aedes species mosquito. The most common symptoms of Zika are fever, rash, joint pain, and conjunctivitis (red eyes). The illness is usually mild with symptoms lasting for several days to a week after being bitten by an infected mosquito. People usually don’t get sick enough to go to the hospital, and they very rarely die of Zika. For this reason, many people might not realize they have been infected or may be infected and have no symptoms.

Zika can also be spread sexually, and has been linked to unusually small heads and brain damage — called microcephaly — in children born to infected mothers, as well as blindness, deafness, seizures and other congenital defects. In adults, the virus is linked to a form of temporary paralysis, called Guillain-Barré syndrome.
