Co-infections with multiple dengue virus serotypes in patients from 3 different Provinces of Sri Lanka, a dengue hyper endemic country

摘要

Background: The circulation of multiple dengue viral (DENV) serotypes in a same locale has caused people to get infected with mixed DENV serotypes in subsequent or simultaneous infections. The objective was to study the clinical presentations together with reverse transcriptase PCR (RT-PCR) and serology of co-infections to identify pattern of disease severity among co-infections in patients from 3 different provinces of Sri Lanka.
