  • Antibody That Blocks Dengue Virus Discovered

    An antibody that blocks the spread within the body of the dengue virus, a mosquito-borne pathogen that infects between 50 and 100 million people a year has been discovered by a team of researchers led by the University of California, Berkeley and the University of Michigan. The virus causes what is known as dengue fever, symptoms of which include fever, vomiting and muscle aches, and can lead to more serious illnesses, and even death. "Protein structures determined at the APS have played ...

  • Dengue Risk Linked to Tap Water Access

    Researchers report that tap water access in densely populated neighborhoods of Delhi, India, is a strong predictor of the risk of contracting dengue. Dengue virus is a mosquito-borne virus that has fast adapted to urban environments, making it the most widespread arbovirus. Around 3.5 billion people are at risk of contracting the virus. The country is in dire need of new strategies to target dengue hotspots and control the virus's spread, even though previous attempts, such as using insecticides ...

  • Link Between Dengue and COVID-19

    People who had dengue in the past are twice as likely to develop COVID-19 symptoms, stated a new study published in the journal Clinical Infectious Diseases. The findings of the study were based on an analysis of blood samples from 1,285 inhabitants of Mancio Lima, a small town in the state of Acre, part of Brazil's Amazon region. The principal investigator was Marcelo Urbano Ferreira, a professor at the University of Sao Paulo's Biomedical Sciences Institute (ICB-USP) in Brazil. The study was supported by FAPESP....

  • New Dengue Related Biological Markers Discovered

    Dengue is the most common mosquito-borne viral disease affecting humans globally. In 2019, the World Health Organization identified dengue as one of the top 10 threats to global health, with transmission occurring in 129 countries and an estimated 3.9 billion people being at risk. Biomarkers are naturally occurring molecules or genes in the vascular, inflammatory or other biological pathways that help to identify the state or risk of a disease in patients. The findings reported in a study published ...

  • Is Dengue Vaccine Effective Against the Disease?

    Unless a dengue vaccine protects against all four different virus types, or serotypes, developing a viable vaccine against dengue virus is difficult. The University of North Carolina health care investigated samples from children enrolled in a dengue vaccine trial to identify the specific kinds of antibody responses that correlate with protection against dengue virus disease to overcome this difficulty. The published study in the iJournal of Clinical Investigation/i discovers that ba small ...

  • Global Warming may Limit Dengue Fever Spread

    Dengue virus makes mosquitoes more sensitive to warmer temperatures, stated new research led by Penn State researchers. The team also found that infection with the bacterium Wolbachia, which has recently been used to control viral infections in mosquitoes, also increases the thermal sensitivity of the insects. The findings suggest that global warming could limit the spread of dengue fever but could also limit the effectiveness of Wolbachia as a biological control agent. "Dengue fever, ...

  • Can Covid Together With Dengue and Malaria Be Treated?

    Hospitals in India witnessed a spike in Covid co-infections, such as dengue and malaria, which could be dangerous and can even be fatal. However, health experts say that it is treatable when given timely intervention. Dengue or malaria are vector-borne diseases spread through mosquito bites and they rise during the monsoon season. Covid, on the other hand, is caused by SARS-CoV-2 virus and transmitted mainly by droplets produced as a result of coughing or sneezing of an infected person. "We ...

  • Engineered Mosquitoes Cannot be Infected With or Transmit Any Dengue Virus: Study

    A new study has found that genetically engineered mosquitoes were resistant to multiple types of dengue virus (DENV). The findings of the study are published in the open-access journal PLOS Pathogens by Prasad Paradkar of the Australian Animal Health Laboratory, and Omar Akbari of the University of California, San Diego, and colleagues. As noted by the authors, this is the first engineered approach that targets all types of DENV, which is crucial for effective disease suppression. Dengue is ...

  • Dengue Prevention: Artificially-infected Mosquitoes may Hold Key to Halting Dengue Spread

    Releasing mosquitoes infected with a type of bacteria could wipe out the spread of dengue, thereby reducing global dengue cases by 90 percent, reports a new study. This is the finding of a team of international scientists, led by Imperial College London, and including researchers from the University of California and University of Florida. The Imperial team, based at J-IDEA, the Abdul Latif Jameel Institute for Disease and Emergency Analytics, created the first ever global map of dengue transmission ...

  • New Zika Vaccine Induces Effective Zika and Dengue Antibodies

    Single dose of an experimental Zika vaccine can improve pre-existing flavivirus immunity and provoke cross-neutralizing antibody responses against both Zika and dengue viruses in a dengue-experienced individual, concluded a study published in iNature Medicine/i. Researchers analyzed the antibody responses of a dengue-experienced volunteer who participated in a Phase 1 clinical trial of the WRAIR-developed Zika purified inactivated virus vaccine. They identified a potent cross-reactive ...

  • Dengue Fever Rising in South-East Asia Alongside Coronavirus

    Coronavirus pandemic has imposed restrictions and lockdown that has prevented communities from engaging in sanitation works, leading to accumulation of stagnant water and detritus. This acts as breeding-grounds for the deadly dengue-virus carrying mosquitoes. This comes as a shock to nations as they scramble to deal with the second wave of the pandemic. The global coronavirus lockdown may have slowed down the spread of the pandemic, but has spurred the dengue fever especially in South-East Asia with Singapore being the worst-hit....

  • New Mechanism for Identifying Drugs for Dengue Discovered

    New mechanism for designing antiviral drugs for dengue virus has been identified. The study details are published in iProceedings of the National Academy of Sciences/i. Dengue virus is a very important mosquito-transmitted viral pathogen, causing 390 million human infections each year. Dengue is common in more than 100 countries and forty percent of the world's population is at risk of infection. When someone becomes ill with dengue, symptoms that can range from mild to severe may include ...

  • New Method Enhances Dengue Vaccination, Paving Way to Wide Use

    New practical way helps induce a strong and broad immunity to the dengue virus based on proof-of-concept studies in mice. Dengue is a mosquito-borne viral disease with an estimated 100 million symptomatic infections every year. It is endemic in over 100 countries in the world, from the United States to Africa and wide swathes of Asia. In Singapore, over 1,700 dengue new cases were reported recently. The study is reported in a paper titled "Sequential immunization induces strong and broad immunity ...

  • Prior Zika Virus Infection Increases Risk of Severe Dengue Disease

    People with Zika antibodies were found to be more vulnerable to severe infection with certain types of dengue, and that could complicate the search for a Zika vaccine, revealed a study published online in the journal i Science. /i The study, which drew on data from two cohorts of Nicaraguan children who lived through a Zika epidemic in 2016 and a dengue epidemic in 2019, is the first to investigate the impacts of Zika immunity on dengue disease in humans. Its findings confirm earlier ...
