Scientists say they have extracted a powerful antibody from a recovered dengue patient in Singapore that can smother and choke the virus to death, a discovery that they hope may offer a new weapon to control the deadly disease. There is currently no cure for dengue which kills 20,000 people a year, many of them children. Physicians can only manage the symptoms. The antibody recovered from Singapore was among 200,000 taken from 100 recovered patients and appeared capable of killing all known strains of the subtype 1 dengue virus, said a paper published on Thursday in the journal Science Translational Medicine.
