The Ministry of Health received the results of genomic sequencing which was conducted through the Caribbean Public Health Agency on samples from the TCI.
These samples were shipped by the National Public Health Laboratory in the TCI from positive samples identified through PCR testing locally. Sequencing was undertaken in order to identify whether any of the variants identified internationally, were in circulation in the TCI. The results of previous testing were received on 27th February 2021, where one case of the B.1.1.7. variant was identified from four samples sent for testing.
An additional 10 (ten) samples were sent for analysis from which an additional 5 (five) cases of the U.K. B.1.1.7. variant was identified. This represents 50% of samples sent in this last batch testing positive for the variant. All of the individuals completed quarantine and have recovered.
The B.1.1.7. variant was first detected in the UK and was first sequenced in the UK in September 2020. This variant includes a mutation in the ‘spike’ protein. Changes in this part of the spike protein may result in the virus becoming more infectious and spreading more easily between people. The COVID-19 virus like any other virus, can undergo mutations. This is well documented in viruses such as the seasonal influenza (flu).
Today’s results were not unexpected due to the TCIs borders being open to international and regional travel as well as the spike in the number of confirmed cases which took place at the end of 2020 into early 2021. This evidence of COVID-19 variants being detected locally does highlight the need for all TCI residents to remain vigilant in protecting themselves and one another through the use of face coverings, social distancing and getting vaccinated.
The Pfizer vaccine, which is being rolled out in the TCI to residents, has been shown to be effective against this variant; however, the general public is reminded to be vigilant in adhering to all public health protocols to prevent the spread of the virus throughout the community.
All residents are urged to be vigilant in practicing the public health measures at all times in light of the ongoing pandemic and surges being experienced in a number of countries both regionally and internationally.
