According to the publication, which cites information from a yet unpublished scientific work conducted by Professor Miguel Nicolelis of Duke University, the increase in the incidence of coronavirus in areas where Dengue outbreaks have previously been recorded has been slower. This may indicate cross-reactivity between the articular fever flavivirus serotypes and SARS-CoV-2. According to the author of the study, if his hypothesis is confirmed, then the Dengue vaccine can be used to fight the new infection. It will provide the body with the necessary immune system response. Earlier studies have shown that people with fever have tested false positives for the presence of COVID-19 antibodies. This fact, according to Nicolelis, may indicate an immunological interaction between these viruses, despite the fact that they belong to different families.
The earliest information about the Dengue outbreak dates back to 1779, but scientists were able to establish the viral cause only at the beginning of the 20th century. Fever has become a huge problem for humanity since the end of World War II. This disease has been reported in more than 100 countries, mainly in South America and Asia. Dengue infects up to 528 million people annually, with up to 20,000 deaths from this type of fever.
