South Africa has recorded the first case of XBB.1.5 variant.

South Africa has recorded its first case of the new highly transmissible XBB.1.5 variant of coronavirus, setting off alarm bells across the continent, including Nigeria, the most populous African nation. This week, Covid-19 technical lead at the World Health Organization (WHO), Maria Van Kerkhove, called XBB.1.5 “the most transmissible sub-variant” detected so far. The new variant is nicknamed the “kraken variant” by some for its ability to spread fast. So far, there has been no significant differences in severity identified between cases caused by XBB.1.5 and those from other variants.

The WHO plans to release an updated assessment on the variant’s risks in the coming days. The head of a gene-sequencing institute at Stellenbosch University, Tulio de Oliveira, said on Twitter that the variant was discovered in gene sequencing carried out by South African researchers at the university from a December 27, 2022 sample. According to WHO, the variant has quickly become the dominant strain in the United States and has been detected in at least 28 countries.

New variant accounts for just one percent of all Covid cases.

More work is being done to identify the new variant in China. China is presently undergoing a surge in infections after relaxing strict controls that limited the impact of the previous waves of Covid in the country. The variant, which was first detected last year, has quickly become the dominant strain in the US. XBB.1.5 is a descendant of the Omicron XBB sub-variant, which is itself a cross between two earlier strains: BA.2.75 and BA.2.10.1. The original XBB variant has already caused waves of infections in countries including Singapore and India since the WHO first raised concerns about it in last October.

There are concerns about how fast XBB.1.5 is spreading. The new variant accounts for just one percent of all Covid cases at the start of December 2022. Estimates from the United States Centers for Disease Control and Prevention show that it has surged to become the dominant strain by the end of the month. Consequently, it was responsible for about 41 percent of all infections. In northeastern states, that figure has jumped to 70 percent.

The proportion of infections caused by XBB.1.5 in other countries is lower.

Van Kerkhove said during a January 4 press conference that XBB.1.5 is “the most transmissible sub-variant which has been detected yet.” Although only 29 countries have reported cases caused by it, health authorities are warning that it could be much more widespread and silently proliferating due to a drop-off in testing. In other countries apart from the US, the proportion of infections caused by XBB.1.5 has remained lower though the situation is likely to rapidly change. As of mid-December, estimates from the Wellcome Sanger Institute found that the new variant caused around four percent of Covid infections in England, while Canada has found only a handful of such cases.

Scientists have noted that the sub-variant has a much stronger affinity to ACE2, a key receptor for the virus, which allows it to bind more easily and boosts its transmissibility. Researchers have also explained that there have been no severity differences reported between XBB.1.5 cases and those previous variants. However, XBB.1.5 is attracting attention because it exhibits signs of immunity escape. In simpler words, it has an ability to bypass natural immunity or previous protection provided by vaccines and re-infect people who have recovered from an earlier bout of Covid.

It hasn’t reach China but Omicron strains still rages.

China is experiencing a major wave of infections after dismantling its stringent Covid Zero policy in recent weeks. However, it has yet to report any domestic case of XBB.1.5. Shanghai, which has detected three infections caused by the variant, said all were imported cases. Contrarily, health agencies around the world, including WHO, have raised concerns that China isn’t providing enough genomic sequencing information to come to any definitive conclusions. Meanwhile, the country’s Covid wave is being driven by two other Omicron strains: BA.5.2 and BF.7. Together, they account for 97.5 percent of all local infections, according to genomic sequencing data from the Chinese Center for Disease Control and Prevention.

I hope this variant of COVID-19 is not passed from one person to another in South Africa. It should be quickly tacked and ensured people don’t transfer it.

The issue of covid case across the globe is really mysterious.The projection giving by the World health and UN toward Africa countries didn’t come to pass because our health system is nothing to write about.

Efforts should be made to identify the new variant and begin work to combating it before it begins to spread. It’s very important.

Preventive measures and efforts should be made to combat it before it begins to spread. A lot should be done in south Africa to curb the discussed.

Before the mutant strain starts to spread, there should be efforts made to determine what it is and then get to work finding a way to stop it. It is of the utmost significance.

Before it can start to spread further, preventative actions and efforts to fight it should be undertaken. South Africa ought to make significant efforts to rein in the discussed.

Stoppage of the disease from spread is priority so it will not spread and cause many issue and difficult to handle curbing the disease with preventive measure

Covid cases are a highly puzzling problem all over the world. Because of the poor quality of our health system, the predictions made by the World Health Organization and the UN for the countries of Africa did not materialize.

Which one is XBB.1.5 variant of coronavirus that is emerging again. We are all in God’s hand. Our government and health care centers nation wide swing into action to prevent it from entering into the country.

SA records case of most transmissible covid. Smiling, how sure is this record from South Africa. Governments in Africa is not sincere, they only love money more than anything. Very soon Nigeria government will bring out Nigeria XBB cases ☺

After China has relaxed its strict Covid Zero policy in recent weeks, it is incomprehensible that the country is currently undergoing a huge outbreak of illnesses.

Since the WHO initially expressed alarm about it, the original XBB type has already been responsible for multiple outbreaks of infection in countries such as Singapore and India.

In spite of the fact that just 29 countries have recorded instances caused by it, health authorities are warning that it may be far more common and quietly expanding due to a drop-off in testing.

The emergency of XBB.1.5 COVID-19 variance calls for care and cautious now that this first transmissible virus has gotten to South Africa. Our government and health care sectors should be at alert and prevent any of such from gaining access into Nigeria.

It is important to make an effort to identify the mutant strain before it begins to spread so that a solution can be found. It’s importance cannot be overstated.
