Medical chief explains ‘community spread’

Medical chief explains ‘community spread’

Chief Medical Officer Dr. Ronald Georges wants the Virgin Islands to know what health officials mean when they talk about “community spread.”

And it’s not his definition: It’s the World Health Organisation’s.

“There are different categories when you’re looking at stages of an epidemic in a country,” he explained. “There can be one or two imported cases. And then you may have clusters of cases, and then you may have larger clusters, and then you have a case where the infection gets in the community and you cannot trace the origin. So when you get to that stage, that becomes community spread.”

According to the WHO, “Community transmission is evidenced by the inability to relate confirmed cases through chains of transmission for a large number of cases.”

Technical terms


In the midst of a pandemic, Dr. Georges said, technical terms surrounding transmission, testing and vaccines get thrown around, and it’s natural that the
public may be confused about what they mean. Knowing what does and doesn’t constitute “community spread” can help prevent panic the next time one or more cases arise, he added.

Last month, three cases were found in contacts of people who had attended a New Year’s Eve party on Virgin Gorda. But even though they became infected in the VI, the situation wouldn’t qualify as “community spread,” the CMO explained.

“If somebody got infected here in the BVI, it doesn’t mean you have community spread,” he said. “It means somebody got infected in the BVI. We’re definitely not in the same boat as the US. We’re not in the same boat
as St. Vincent and Barbados.”

Those Caribbean countries saw major spikes this month that sent active cases soaring from double digits to triple digits in St. Vincent and quadruple digits in Barbados.

“Even though in the last month you’ve had a large number of cases [in the VI], those cases are all contained. … And you didn’t hear anything exciting from the government; there was no shutdown. Every last one of them was traced and tracked and every one of them was put under control and they were of no risk
to anybody.”

‘We found nothing’


Furthermore, when health officials engage in mass testing, such as what occurred on Virgin Gorda and Tortola in the wakeof the New Year’s Eve cases, it doesn’t mean they expect to find massive numbers of cases.

It just means that because the VI is a small territory, officials are being cautious, according to Dr. Georges.

“We did not think there were any transmission links. But just to be overly cautious to make sure that nothing slipped out, we went and mopped up,” he said. “[We told] anybody who went to[those] parties to come and get tested, so that was kind of likea secondary thing we did. And we found nothing.”
