All viruses change over time, which gives rise to new variants, such as the case of SARS-CoV-2, explains the World Health Organization, mutations that are the product of the greater spread of the virus.
“High levels of transmission mean that we should expect more variants to emerge,” said the WHO.
These variants do not always represent a direct benefit for the virus and “may even be detrimental to its spread”, however the WHO recognizes that further research is necessary to understand the impact of a “mutation on the properties of the virus and its efficacy. of diagnoses, treatments and vaccines ”.
The first step is detection and some countries have already reported the presence of new strains. One of the first detected was that of the United Kingdom, which has spread to at least 60 other countries.
The British variant of the coronavirus is considered much more contagious and now health authorities are beginning to gather evidence that it is also more deadly, as reported this Friday by Boris Jonson, Prime Minister of the United Kingdom.
“Now there also seems to be some indication that the new variant, the one first identified in London and the South East [de Inglaterra]It may be associated with higher mortality ”said the president.
He added that current evidence continues to show that the two vaccines used in that country are still effective for both variants.
This variant, until January 13, has already been detected in Brazil, Canada, Chile, Ecuador, Jamaica, Mexico, Peru and the United States.
A second variant originating in Brazil has been identified in 23 countries, according to the WHO, including Germany.
The authorities indicated that the infected person recently returned from a trip to Brazil and laboratory tests in the state of Hesse confirmed that he had been infected, four people who traveled from Brazil were also detected in Japan.
Panama also notified the case of a passenger from South Africa, who was in quarantine since his arrival in the country.
“This is a 40-year-old passenger, born in Zimbabwe, who entered the country on January 5 from South Africa and had previously made a stopover in the Netherlands before arriving in Panama,” the ministry said in a statement; Similarly, Cuba detected an imported case.
Some countries have increased restrictions on flights from abroad, such as Belgium, which has banned its citizens from non-essential travel from January 27 to March 1. The WHO maintains its position against this type of measure.
