Every week there are numerous scientific studies published. Here’s a look at some of the more interesting ones.
More Worries About Emerging Viral Diseases
If the current COVID-19 pandemic is teaching the world anything, it’s that viral diseases can be extremely dangerous and disruptive. Researchers with the University of Colorado Anschutz Medical Campus released a new study calling attention to the emergence of mosquito-borne viral outbreaks in West Africa, including dengue (DNV), chikungunya (CHIKV) and Zika (ZIKV) viruses. They published their research in Acta Tropica .
The study reviewed 50 years of literature on arboviruses in West Africa. The goal was to define evidence of DENV, ZIKV and CHIKV and the distribution of their Aedes mosquito vectors in the region. They found strong evidence that transmission of these diseases is occurring in urban areas of West Africa, which is distinct from the rural transmission of yellow fever virus that has been historically present in the region. They found evidence that the epidemiology of arboviral disease in West Africa has shifted and that rapid urbanization and climate change could increase risk of outbreaks in the future.
“Large arboviral outbreaks will occur around the world,” said Elizabeth Carlton, assistant professor of environmental and occupational health at the Colorado School of Public Health and co-author of the study. “Building awareness and surveillance capacity before the outbreaks occur can help detect outbreaks early and enable prompt and effective response to reduce health impacts.”
Research lead Andrea Buchwald, a postdoctoral fellow, said, “Emerging viruses are at the forefront of everyone’s attention due to the COVID-19 pandemic. It has underscored the importance of preparing for and preventing large […]
