Study indicates that it is possible to contract zika, dengue and chikungunya in a single bite

For analysis, the team infected mosquitoes in the laboratory with all three virus types. Then they performed tests to verify the rate of transmission. The results showed that viruses can reproduce without dominance of one or the other in the organism of Aedes aegypti.

"Double infections in humans are quite common and may be even more common than we imagine in theory the mosquito can infect someone with multiple viruses at one go, "said Claudia Rückert, a postdoctoral fellow at the CSU's infectious disease and arthropod laboratory.

Scientists hoped that one of the viruses was more dominant than others, thus eliminating them from the mosquito and making them no longer transmissible to humans. "It's interesting how the three Aedes aegypti-transmissible viruses replicated together in the mosquito's body." "Based on what I know as a virologist, epidemiologist, and entomologist, I think viruses want to compete or help between they all have mechanisms to suppress the immunity of mosquitoes, which can be done in synergy. On the other hand, they all probably require similar resources inside infected cells, which can generate competition, "said Greg. Ebel, co-author of the research.

Although the finding is surprising, research is still sparse and contradictory, so it's hard to believe that co-infection can be more serious than being hit by a single virus. Nicaragua analyzed a large number of coinfections but did not observe changes in the hospitalization of the patients or in the clinical state. However, other studies have shown that multiple infections can cause neurological complications.

According to the researchers, the diagnosis of coinfections is essential to finding the correct treatment. "It depends a lot on how the diagnosis is made and what doctors will evaluate at the moment, they may not notice that there is another virus present and this can lead to misinterpretation of the severity of the disease," said Claudia. aims to analyze the relationship between different viruses in the body of mosquitoes. "We will study how these interactions, between virus and mosquito, change when there are two viruses, which is transmitted from a coinfected mosquito and how it differs from a mosquito infected with only one virus."

Study says some deodorants may cause breast cancer

Women who regularly use deodorants with salts may be at increased risk of developing breast cancer. Scientists have argued that long-term exposure to aluminum chloride may lead to an increased risk of heart disease, a new study by the University of Geneva, Switzerland, and published by the International Journal of Cancer .
