Doctor Alexander Pupo warns about the dangers of dengue in coronavirus mutations

Added to the appalling management of the coronavirus in Cuba is the increase in dengue cases, both viruses with similar structure and symptoms that, if they converge in the human body, can bring lethal consequences, the doctor warned Alexander Raúl Pupo Casas.

Regarding COVID-19, “The scenario remains the same,” said the doctor during the broadcast of this Monday of The mornings of CiberCuba. “Many cases of COVID, few resources in the case of doctors to care for patients, clouds regarding the actual figures that are being published and, now, an epidemic of Aedes aegypti mosquitoes”, he specified.

The doctor said that the presence of the transmitting insects, among other diseases, of the dengue virus “has people very worried”, because they no longer only disturb “at night; now during the day at any time of the day there is a total epidemic ”. Another epidemic, that is, that in Cuba there is a syndicate or, in other words, there is more than one epidemic.

“And that is extremely dangerous,” warned Pupo Casas, especially because “Dengue and coronavirus are RNA viruses that, if both colonize the same cell, if both infect the same cell, a mutation can easily occur in both of them”, he specified.

Mutations or transformations of a virus can give rise to the birth of a new strain or variant of the virus that, in the case of Cuba, may not yet have been identified. In a patient with dengue and COVID at the same time, the double burden can lead to a mutation of coronavirus or dengue “or worse, a new virus,” he said.

“This causes a state known as ‘double charge’ which is an ideal space for mutations”, which, in his opinion, could explain the deaths and the high number of infections with respiratory symptoms in Cuba, the doctor later explained to CiberCuba.

They are all possibilities. So far, there is no official or scientific information that can prove that there is a “Cuban strain” or a new virus. What is certain is that dengue and coronavirus (with the different variants and patterns that are confirmed in Cuba) dangerously coexist on the island after the opening to tourism in 2020.

According to A study conducted by Cuban scientists, “between March and September of last year the predominant variant on the island was D614G, derived from the original from Wuhan, but between the end of December 2020 and the end of March of this year, five genetic variants and six mutation patterns ”.

The variants of SARS-CoV-2 that inhabit Cuba today are that of the United Kingdom (also called Alpha), that of South Africa (Beta), that of Brazil (Gamma), that of India (Delta) and that of California (Epsilon) .

Both epidemics (dengue and coronavirus) share similarities in symptomatology, which makes diagnosis difficult and masks it. Not only is there the risk that the fever caused by COVID is understood as dengue fever by the doctor, as has already happened, but that “It can provoke a crossed immune response, that is, inaccurate, further complicating the evolution of patients”the doctor pointed out.

In other words, both the doctor and the body itself can “get confused” when dealing with a viral mutation. Both mistakes, that of science and that of Mother Nature, can be fatal to the patient.

“I think the mutations of the virus itself is the most feared issue by the medical community due to the resistance of the vaccines that have been implemented”added the doctor.

“RNA viruses that have great facility to mutate, each time a new strain emerges, the vaccine is likely to have no immunity against that strain” or, alternatively, it is necessary to resort to “an additional dose of the vaccine … to be able to immunize “, the doctor sentenced and mentioned as an example vaccines of foreign invoicing.

This Monday Cuba woke up with 8,342 new positives to the coronavirus, for a total of 39,610 active at the moment. An average of around 85 deaths a day in the last week, with a worrying increase in the population at risk such as pregnant women and children.
