THE new COVID-19 variant, C.1.2, first detected in South Africa and a few other countries a few months ago, has reportedly spilled into Zimbabwe amid fears it could trigger the fourth wave of the highly infectious respiratory disease.
Although the variant is not yet listed by the World Health
Organisation (WHO) as a disease of concern, it is famed for being the most
mutated and has kept scientists on their toes in the past few days.
Renowned scientist Penelope Moore of South Africa’s National
Institute of Communicable Diseases, who is also an associate professor at Wits
University, said the variant had been detected in Zimbabwe as well as Zambia,
Mauritius, and the United Kingdom (UK).
She made the remarks on South African broadcaster eNCA on
Tuesday. “It has been picked up in the UK, Mauritius, Zimbabwe and Zambia,” she
said. However, local health experts yesterday said they had not yet detected
the alleged variant.
National COVID-19 taskforce co-ordinator Agnes Mahomva said
they had not yet received information to that effect.
Raiva Simbi, deputy director of laboratory services in the
Health and Child Care ministry said their last genome sequence report in June
did not pick up the variant. “We will only know after the next genome sequencing
report for July/August.”
The report is expected in two weeks’ time. Simbi also said
the C.1.2 variant was not yet on the list of WHO’s variants of concern. “For
now, it is still a variant of interest until further research and study,” he
said.
But South Africa’s National Institute for Communicable
Diseases and the KwaZulu-Natal Research Innovation and Sequencing Platform
expressed concern over the variant because of how quickly it has mutated.
It is between 44 and 59 mutations away from the original
virus detected in Wuhan, China, making it more mutated than any other
WHO-identified variant of concern or interest.
It also contains many mutations which have been associated
with increased transmissibility and a heightened ability to evade antibodies in
other variants, the scientists said, though they occur in different mixes and
their impacts on the virus are not yet fully known.
The variant was first detected in May this year. It is said
to be a descendant of the C.1.2 variant and has not been named due to the fact
scientists are still analysing it.
Zimbabwe is currently grappling with the Beta aand Delta
variants first detected in South Africa and India, respectively.
In her interview with eNCA, Moore added: “Every infection
gives the variants an opportunity to mutate and any mutation that the variant
picks up gives it an advantage whether that is transmissibility and resistance
to antibodies; that mutation is going to spread.
“As long as we have infections, we are expecting to pick up
these variants. We really need to get the vaccines out globally, if we can get
everyone to get the vaccines that will reduce the spread of SARS-CoV-2 globally
and that is the only way we can reduce the number of variants that we will pick
up. This is a part of our lives going forward.”
C.1.2 has since been detected across the majority of the
provinces in South Africa and in seven other countries spanning Africa, Europe,
Asia and Oceania.
The C.1.2 lineage has drawn the attention of scientists
because despite its low rate in the population, it possesses mutations within
the genome similar to those seen in variants of interest and variants of
concern, like the Delta variant. Newsday
