  • 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 ...

  • New Ultra-sensitive Test for Dengue Virus Created

    Structurally designed DNA star was found to create a ultra-sensitive test for the dengue virus, said researchers. Published today in Nature Chemistry, this detection technique could be expanded to other viruses and adapted to kill the viruses it snares. "This is more sensitive than any other way of detecting Dengue, beating the clinical test by more than 100 fold," said Xing Wang, the corresponding author of the study, an assistant professor of chemistry and member of the Center for Biotechnology ...

  • Plant Based Compound Improves Response to Dengue Vaccine: Study

    Plant-based compound called halofuginone improves the immune response to a potential vaccine against dengue virus, according to study published in iScience Signaling/i by researchers at the University of Hyderabad in India and the Cornell University College of Veterinary Medicine. Halofuginone tricks the body into thinking it is starving for amino acids, which activates a pathway that results in more, and better, antibodies that are better at neutralizing the virus. The compound could ...

  • Dengue Outbreak Kills 27, Infects 44,000 People in Bengal

    Bengal is now facing an outbreak of dengue (a deadly mosquito-borne disease) which killed 27 people and infected nearly 44,000 cases. At least 27 people have died, and around 44,000 people afflicted with dengue in West Bengal this year, Chief Minister Mamata Banerjee told the state Assembly on Tuesday. She, however, claimed that the number of dengue-related deaths have gone down this year. "Last year, 86 people had died of the disease. This year the number of deaths have come down to 27....

  • Stop Dengue: New Tool to Track the Global Spread of Dengue

    Newly designed tool can now predict the global spread of human infectious diseases such as dengue at their source. Hence, spotting a wide range of deadly mosquito diseases at their source could save millions of lives.

  • 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....
