Northern Territory (NT) officials say they will know if the source of Catherine is associated with a second cluster growing there and a cluster on the Robinson River after genomic testing results return Thursday. increase.
This is because a 21-year-old woman from Cairns sowed the first outbreak, spent the night with a Wehrmacht contractor in Darwin, and then returned to Catherine to infect her cohabitants. The woman was found to have lied to authorities about her recent trip to Victoria, known as the hotspot for the delta variant of COVID-19. Australian person report.
Authorities believe she is also likely to be the source of the second Catherine Cluster and the Robinson River, now collectively known as “Catherine-Robinson River Cluster 2” at 19.
“There is no established link between Cluster 1 and Cluster 2. This is the most likely explanation, but we will continue to investigate genomic results until tomorrow,” Prime Minister Michael Gunner said Wednesday.
How Genome Testing Works
Genome sequencing has played a major role in supporting the mapping of COVID-19 infections.
according to Queensland Genomics, Genome sequencing takes the “gene fingerprint” of an organism and creates a map of how its DNA and RNA are ordered.
Because COVID-19 is an RNA virus, scientists can sequence genes in different cases to detect small differences in each of the new infections. This allows the creation of a genetic family tree and shows which COVID-19 cases are closely related.
The more fingerprints you get, the easier it is to identify if you have been infected with a virus from a known cluster or case.
New cases of the Katherine and Robinson rivers
As of Wednesday NT Health said There were 8 new cases in 24 hours, 3 from Catherine and 5 from the Robinson River.
Three cases of Catherine, two Aboriginal men in their thirties and a 21-year-old Aboriginal woman, are all household contacts for previously recorded cases. Five from the Robinson River are also household contacts in previous cases, including a 3-week-old Aboriginal girl.
All of them are currently quarantined at the Howard Springs Quarantine Facility’s National Resilience Center (CNR).
Contract tracking is underway and 234 close contacts have been identified, 107 of which have been quarantined and tested.
After going to the Robinson River from November 11, those who have left the area and have not been vaccinated should be immediately tested and self-quarantined until the test results are negative. Fully vaccinated people who do the same do not need to be quarantined, but must be tested within 3 days.
The same requirements apply to anyone who has visited the city of Catherine, including Tindal, since November 7th and is currently away from the area.
