There are more documented influenza cases for this period compared to previous years, according to the Ministry of Health’s Epidemiology Division’s Technical Director Dr Avery Hinds.
Speaking at Wednesday’s virtual COVID-19 press briefing, Hinds said the main influenza strain currently in circulation in T&T is H3N2.
“The number of cases so far for this point in the year, or up to this point in the year, actually just exceeds the number of cases that would have been detected last year,” Hinds said.
However, he said this could be a result of the way they tested for the virus.
“We have to bear in mind the testing was more focused on COVID-19 last year to some extent at the expense of other testing, because the resources for testing all of these viruses are shared. It’s the same people, the same machines, it’s really whether you use them to do one test or another, so it may not be a fair comparison,” he said.
This year, he said testing has been increased for respiratory ailments, which could be why larger numbers of influenza are recorded.
Influenza season runs from October to May but Hinds said it can spread outside of this window.
“Influenza doesn’t actually read the book on seasons, so influenza will spread once it gets into a population and there’s lots of movement,” he said.
“We had a lot of movement within this July/August period. We would have had a reintroduction of travel, bringing things from other countries into our population in a pattern that would differ from other years because there was a reduction in mobility, followed by a removal of those restrictions and spikes in travel in points in time that don’t correspond to the normal travel period.”
On the COVID-19 front, he said there was a decrease in new infections, which he hopes is a sign the BA.5 Omicron sub-lineage has run its course.
