According to the Brazilian professor Miguel Nicolelis, from Duke University (USA), the cases of coronavirus were compared with the spread of dengue between the years of 2019 e 2020. The study coordinator stated that the locations that registered a low level of coronavirus contamination were the most affected by dengue in the last few months.
This can explain This is why several regions in the country have shown a slow growth in COVID-19 related cases. In Paran, Santa Catarina, Rio Grande do Sul, Mato Grosso do Sul and Minas Gerais, high levels of dengue were detected last year and earlier this year. Unlike Amap, Maranho and Par, who achieved few cases of dengue.
In a Reuters interview, Nicolelis said that previous studies showed that people infected with dengue can show results false positive for COVID-19. “This indicates that there is an immunological interaction between two viruses that no one could expect, because the two viruses are from completely different families,” he said.
For the teacher, the relationship between the virus that transmits dengue (Flavivirus) and that of COVID-19 (SARS-CoV-2), can bring great possibilities immunity. “If proven to be correct, this hypothesis could mean that dengue infection or immunization with an effective and safe vaccine against dengue could produce some level of immune protection against the coronavirus,” he said.
The discovery was a surprise for those involved in the study, and took place during a study on the progress of COVID-19 in Brazil through highways. The team headed by Professor Miguel Nicolelis said that further studies are needed to confirm the veracity possible immunity and, therefore, the study has not yet been published.
Covid-19 cases in Brazil
Brazil is in third place in infection numbers of the new coronavirus. With more than 4.4 million cases, the country is only behind the United States and India, which have, respectively, 6.8 and 5.4 million infected.
