New coronavirus variant ‘Mu’ under close scrutiny by WHO 0
The World Health Organization has said it is monitoring a new coronavirus variant known as “Mu”, which was first identified in Colombia in January 2021.
Mu, known scientifically as B.1.621, has been classified as a “variant of interest”, the global health body said Tuesday in its weekly pandemic bulletin.
The WHO said the variant has mutations that indicate a risk of resistance to vaccines and stressed that further studies were needed to better understand it.
“The Mu variant has a constellation of mutations that indicate potential properties of immune escape,” the bulletin said.
There is widespread concern over the emergence of new virus mutations as infection rates are ticking up globally again, with the highly transmissible Delta variant taking hold – especially among the unvaccinated – and in regions where anti-virus measures have been relaxed.
All viruses, including SARS-CoV-2 that causes Covid-19, mutate over time and most mutations have little or no effect on the properties of the virus.
But certain mutations can impact the properties of a virus and influence how easily it spreads, the severity of the disease it causes, and its resistance to vaccines, drugs and other countermeasures.
The WHO currently identifies four Covid-19 variants of concern, including Alpha, which is present in 193 countries, and Delta, present in 170 countries.
Five variants, including Mu, are to be monitored.
After being detected in Colombia, Mu has since been reported in other South American countries and in Europe.
The WHO said its global prevalence has declined to below 0.1 percent among sequenced cases. In Colombia, however, it is at 39 percent.

Africa Covid death toll tops 200,000 0
More than 200,000 people have died from Covid-19 in Africa since the start of the pandemic, according to an AFP tally compiled from official records as of 1700 GMT.
A total of 200,254 fatalities have been registered in Africa, home to more than 1.3 billion people, since the virus emerged in China in December 2019.
After several deadly months, including some 27,000 deaths in July and 26,000 in August, the pandemic appears to be easing on the continent, with current daily figures of 617 compared to up to 990 in late July, a record for the region.
The figures are based on tolls communicated daily day by health authorities in each country or by the UN’s World Health Organization (WHO) and include the countries of North Africa.
The WHO has said that if excess deaths directly or indirectly linked to Covid are taken into account, the real toll could be double or triple.
The total number of infections is also likely to be an under-estimate, given insufficient testing capacity in Africa.
“It’s probably a lot higher than that,” said researcher Glenda Davidson of South Africa’s Cape Peninsula University of Technology. “Testing resources are very low on the continent.”
Death registration processes were often delayed and inaccurate, she added.
The current fall in the continent’s tally is a result of sharp drops in the hardest-hit countries.
South Africa has recorded 83,899 deaths so far. But last week’s daily average of 7,400 new cases and 234 deaths is significantly lower than in late July, when the daily average was up to 20,000 new cases and 420 deaths.
– Vaccination key –
The decrease has been even more striking in Tunisia, which has recorded a daily average of 1,680 cases and 64 deaths: 41 and 39 percent down on the previous week.
The figures are well below those of July, which were described by the government as “catastrophic”, with up to 7,900 cases and 207 deaths daily.
Tunisia’s summer was also marked by a sharp acceleration in its vaccination drive, with nearly 37 percent of the population having received at least one dose, compared to just 11 percent on July 1.
Africa has seen the lowest vaccination rate to date of all the continents, with only eight jabs administered per 100 inhabitants administered, according to an AFP count, compared with 102 in Europe and 116 in the United States and Canada.
According to the WHO, around three percent of sub-Saharan Africa’s population are fully vaccinated. By comparison, 52 percent of people are fully vaccinated in the United States of America and 57 percent in the European Union.
“The inequity is deeply disturbing. Just two percent of the over five billion doses given globally have been administered in Africa,” WHO Africa chief Dr Matshidiso Moeti said last week.
However, inoculation in South Africa has been picking up after a rocky start.
“The vaccine has been our weapon,” said South African public health practitioner Shakira Choonara.
“It is contributing to certain changes in trends we are beginning to see.”
