The National Director of Epidemiology at the Ministry of Public Health, Dr. Francisco Durán García, warned this Wednesday on national television about the possible circulation in Cuba of a new subvariant of the coronavirus, identified as XFG, also known as Stratus, which is a descendant of the Omicron variant.
During his usual appearance on national television, Durán explained that although this subvariant has not been officially detected in the country, "it is very possible that it is present," due to its widespread global transmission and the fact that it can be transmitted during the asymptomatic period.
"It is very difficult for an asymptomatic carrier not to arrive, and then for symptoms to appear and the disease to be transmitted," warned the specialist, who had dispelled rumors last March about the circulation of a new variant of COVID-19 in Cuba.
According to the specialist, the XFG causes a clinical picture similar to that of previous variants of the virus, with symptoms such as hoarseness, sore throat, mild fever, and, in some cases, digestive discomfort.
Although the vaccines —including the Cuban ones— have shown effectiveness against this subvariant, the epidemiologist urged the public not to be complacent and to enhance their protective measures.
Durán emphasized the importance of reinstating personal protective measures in light of the potential circulation of this new subvariant, whose widespread global presence had already been warned about by the World Health Organization since May.
He emphasized that individuals with respiratory symptoms should avoid leaving home, and if they must go out, they should wear a mask as a precautionary measure.
It was also recommended to continue using face masks in closed spaces, during gatherings, in lines, or on public transportation, as well as to adhere to the vaccination schedule set for the corresponding groups.
It also emphasized the importance of frequent handwashing as a basic preventive practice and the need to maintain physical distancing, especially in contexts with a high concentration of people.
“Every precaution is still insufficient,” warned Durán at the end of his speech, in which he also reported that currently there are 4,659 people hospitalized with dengue at various levels of the Cuban healthcare system, although none are in serious condition or in intensive care units.
He noted that five provinces and six municipalities are experiencing active transmission of arboviruses, as part of an anticipated increase due to the heat and rainy season.
Regarding the Oropouche virus, he noted that it affects a greater number of provinces, municipalities, and health areas than dengue, but emphasized that it does not cause serious complications, and its clinical presentation is milder, especially in individuals who receive timely medical care.
Despite this, he reiterated the need to stay vigilant and consult a doctor at any sign of suspicious symptoms.
Frequently asked questions about the new coronavirus variant in Cuba and the current epidemiological situation
What is the XFG subvariant of the coronavirus and what are its symptoms?
The XFG subvariant, also known as Stratus, is a descendant of the Omicron variant of the coronavirus. It causes a clinical picture similar to that of previous variants, with symptoms such as hoarseness, sore throat, mild fever, and, in some cases, digestive discomfort. Although it has not been officially detected in Cuba, its presence is suspected due to its widespread global transmission.
Are the current vaccines effective against the XFG variant in Cuba?
The current vaccines, including the Cuban ones like Soberana and Abdala, have proven to maintain their effectiveness against the XFG subvariant. Despite this, the population is advised not to let their guard down and to take extra protective measures, such as wearing masks in enclosed spaces and crowded places.
What is the current situation of dengue and the Oropouche virus in Cuba?
Currently, there is active transmission of dengue in three provinces, four municipalities, and four health areas in Cuba. The Oropouche virus is also circulating in seven provinces and ten municipalities. Although no severe cases have been reported, these diseases remain a concern due to the high infestation of the vector mosquito in various regions of the country.
What preventive measures are recommended in Cuba to avoid the spread of coronavirus and dengue?
It is recommended to continue using a face mask in enclosed spaces and in crowded situations. Additionally, the vaccination schedule should be followed, frequent handwashing should be practiced, and physical distancing should be maintained. To prevent dengue, it is essential to eliminate mosquito breeding sites and uphold personal and household hygiene.
