India’s dengue burden grows more complex as multiple virus strains circulate together, study finds
India's dengue epidemic is worsening as a study reveals simultaneous circulation of all four dengue virus serotypes, raising concerns about increased disease severity. Conducted by the Indian Council of Medical Research, the study found that over 7% of patients were infected with multiple serotypes, with DENV-2 being the most prevalent. This co-circulation poses challenges for future vaccination efforts and suggests a potential rise in severe dengue cases.
