At the meeting of the Joint Select Committee on the Covid-19 Pandemic and Related Matters that was held at Parliament this week Tuesday (July 20, 2021), National Epidemiologist Dr Karen Webster-Kerr gave an update on Jamaica’s Covid-19 situation, using data as of July 19.
A copy of the slide presentation presented by Dr Webster-Kerr is available here:
Dr Webster-Kerr noted the increase in the number of new cases and the positivity rate that has been seen in the past couple of weeks.
She pointed out that the Reproductive Rate of the virus is once again over 1, now being at 1.1. This means that Jamaica is again experiencing exponential spread of the virus, albeit at a slow rate of spread. This rate could easily increase sharply without preventative measures.
One of the questions that has been asked frequently in recent weeks is whether the more contagious Delta variant is now present in Jamaica, particularly since it has now become the main strain of Covid-19 being seen in the UK and the USA, both being countries which see a lot of air travel with Jamaica. In Parliament last week, Minister of Health Chris Tufton said that genetic sequencing test results from samples sent to the CDC had not shown the presence of the Delta variant. When asked by Opposition MP Morais Guy, however, he was unable to say when those samples had been collected.
A slide in Dr Webster-Kerr’s presentation dealt with the samples sent for genome testing since December 2020 and indicated that the most recent results received were still those from the CDC.
However, in response to MP Guy’s question about how recent the samples were that had been sent for testing, Dr Webster-Kerr said that the samples sent to CDC on June 8, 2021, were mostly taken in May, with three from April and two from June. The samples sent to PAHO’s lab in Brazil on June 24, 2021, were mainly from April and May with a few from June.
This highlighted the point that the samples from which we have received results are too old to give any clear indication of whether or not the Delta variant is now in Jamaica.
Minister Tufton also responded on the issue of the samples and the Delta variant:
I think we have to be as straightforward with the country as possible, not just on the evidence based on the tests done but on the likelihood based on projections and circumstances. I think you raised an important point, Member [Morais Guy], on questioning the recency or age of the samples that were collected. And I think it’s quite clear that based on the dates around those samples the likelihood of picking up the Delta variant at that time would be less than it would be presently. And I think the most recent samples, the ones that are to go off, which would contain samples of June and hopefully July, would be our key insight, if you will, into whether the Delta variant is here.
These things normally not advisible to give a personal view but certainly based on the interactions that we are having as an open society with other geographic spaces that have the Delta variant as a dominant feature of those populations, I certainly believe that it is just more a matter of time before we detect that that variant is here. And I think the true, the same could be said for other populations throughout the world. This is the nature of the virus, this is how it spreads and once you are exposed with borders that are open of necessity, for trade or otherwise, you are going to have that level of exposure.
So I do believe that a more accurate reflection of what is present in the population as it relates to variant strains will come from the most recent batch of samples collected and I think the country should be advised of that and should continue to observe the protocols in anticipation that we are likely to have the Delta variant.

The Clinical Management Summary posted by the Ministry of Health and Wellness (MOHW) yesterday, giving the figures for Tuesday (July 20, 2021) added to the concerns being expressed. The number of new cases recorded was 111, which was the first time since May 27, 2021, that the number of new cases recorded in a day had gone over 100; it was 108 on that day. Also, the positivity rate was 16.1%; a rate higher than that had not been recorded since May 5, 2021, when it was recorded at 18.7%
In Parliament on Tuesday, Prime Minister Andrew Holness made a statement regarding the Covid-19 situation and indicated that the Cabinet Covid-19 Sub-Committee would be meeting on the weekend and that if the trends continued, tighter restrictions might be announced. Such an announcement might be made next week Tuesday.
In an interview with Dionne Jackson Miller on RJR’s Beyond the Headlines yesterday evening, epidemiologist Professor Peter Figueroa expressed concern about the point that Jamaica is now at, with an increase in cases and a Reproductive rate of 1.1.
We are facing an imminent surge of the Delta, it’s probably the Delta variant and that can be very swift with an increase in cases. We need measures immediately….I’m concerned because we cannot afford to watch and wait. When you look at the data, when you start to get an increase in cases, it rises rapidly.
Professor Peter Figueroa, Beyond the Headlines, July 21, 2021 (Transcribed from recording)
There seems to be a general consensus that if the Delta variant is not actually here yet, it will be sooner or later. And there are many who see the recent increases as an indication that we are already on the verge of a third wave of Covid-19 in Jamaica.
