One Strain of Dengue Protects Against the Others

An article in The New York Times reports that “infection with one strain of the dengue virus gives people protection against the other three strains for about two years.” A study used 38 years worth of laboratory records from a children’s hospital in Bangkok to calculate the duration of protection. The mosquito borne virus had completely disappeared in the United States for 40 years until resurfacing in 2009. The virus is now endemic to Key West, Florida. Researchers see promise in developing a vaccine for dengue because it has a small enough number of strains to make it “just right” for studying cross protection.
