Dengue Fever News and Research

RSS

Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Symptoms typically begin three to fourteen days after infection. These may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash.

Hidden "super spreader" spaces associated with a predominance of asymptomatic cases of dengue

For mosquito-borne diseases such as dengue fever, the abundance of the insects in places where people gather has long served as the main barometer for infection risk.

Mapping specialized receptors on mosquito nerve cells reveals why the insects are more attracted to some humans

In a bid to understand why mosquitoes may be more attracted to one human than another, Johns Hopkins Medicine researchers say they have mapped specialized receptors on the insects' nerve cells that are able to fine-tune their ability to detect particularly "welcoming" odors in human skin.

New precision-guided sterile insect technique designed to control disease-spreading mosquitoes

Leveraging advancements in CRISPR-based genetic engineering, researchers at the University of California San Diego have created a new system that restrains populations of mosquitoes that infect millions each year with debilitating diseases.

Researchers use gene editing to render male mosquitoes infertile and slow disease spread

Mosquitos spread viruses that cause potentially deadly diseases such as Zika, dengue fever and yellow fever. New U.S. Army-funded research uses gene editing to render certain male mosquitoes infertile and slow the spread of these diseases.

Quick, inexpensive leptospirosis test strip kit to help lower death and disability risk

The Faculty of Medicine, Chulalongkorn University has brought out a quick, inexpensive, and easy-to-use leptospirosis test strip kit to help lower the risk of disability from internal organ failure and death, with the hopes of distributing them to community hospitals across the country.

Mapping dengue fever hot spots can predict future outbreaks of Zika and chikungunya

Data from nine cities in Mexico confirms that identifying dengue fever “hot spots” can provide a predictive map for future outbreaks of Zika and chikungunya. All three of these viral diseases are spread by the Aedes aegypti mosquito.

Differences in monocyte subsets between severe COVID-19 and long COVID

Researchers in the United States and Costa Rica have identified differences in the proportions of monocyte subsets that occur in severe cases of coronavirus disease 2019 (COVID-19) following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and post-acute sequelae of COVID-19 (PASC), often referred to as “Long COVID”.
