KARACHI: The Aga Khan University Hospital (AKUH) confirmed on Wednesday the detection of six coronavirus cases belonging to the highly-contagious Omicron subvariant category XBB in Karachi.
“We have detected six cases, however, others have been found around the country,” AKUH Infectious Diseases Sec-tion Head Dr Faisal Mehmood told media. “These have started since November.”
According to the World Health Organisation (WHO), the XBB is a highly contagious subvariant of Covid-19’s Omicron strain. As per early evidence, the XBB variant had a higher reinfection risk, as compared to other circulating Omicron sublineages.
A statement by the US Centres for Disease Control (CDC) on Dec 31, around 40pc of confirmed US Covid-19 cases were caused by the XBB.1.5 strain, a relative strain of the XBB variant. Dr Mehmood said the XBB variant can spread rapidly, especially in people who do not have pre-existing immunity from vaccination or previous infections.
“The symptoms are similar to the other Covid variants,” he added, encouraging vaccinations for people who have not received the booster shot or have low immunity. The infectious diseases expert said adequate amounts of testing were the most important thing to counter the new variant’s spread. He advised the public to get a booster shot if they haven’t already. “If you have any symptoms, you should get tested or at least wear a mask and avoid other people to prevent the spread of the virus,” he said. “If your immunity is low because of age or other medical conditions, avoid crowded areas, adopt masks, and ensure your vaccinations are up to date.”

Commenting on whether the vaccines administered in the country would provide protection against the XBB variant, the AKUH expert said: “The new variants are able to still infect people who have had the vaccination, however, the symptoms tend to be mild.”

When asked if the presence of the variant could prompt a new lockdown, Dr Mehmood said it was “highly unlikely” and “will not be required”. “We do not expect to see a surge the way that China is which is in a different situation giv-en that most of the population is not immune and vaccination which was not as effective,” he said. “China recently reduced their lockdown which has left a large number of the population vulnerable to the virus.”

Separately, spokesperson for the Sindh Health Department, Mehar Khursheed, told media that cases of the XBB vari-ant were not a cause for concern since the strain was the predominant one across the world. “All of Sindh’s population is vaccinated with double doses, boosters are being administered as well,” she said, adding that children were also be-ing vaccinated in populous areas.
