Abstract

Background: With more than one-third of the world’s population living in areas at risk for infection, dengue virus is a leading cause of illness and death in the tropics and subtropics.

This study aimed to determine the serofrequency of IgM among Febrile patients attending portsudan hospital during May to August, 2014 at Red Sea State.

Methods: This was descriptive cross sectional study in which consenting patients with symptoms fever and joint pain ) were included theirn age rang 1 to 56 with mean 27.7 . 90 plasma samples were tested by semi-quantitative enzyme linked immune sorbent assay for presence or absence of anti dengue virus (IgM) and relation of serofrequency with gender,age, platelets counts and pain joints were also detected .

Results: The frequency of IgM among 90 febrile patients attending portsudan teaching hospital was 97.7(n=88), seropositivity was 55.5%(n=50) of males and 42.2%(n=38) of females , the highest results among age groups was obseved among 1-18 years age range (43.3%). All patients had thrombocytopenia with platelets count ranged from 80, 000 to 150,000cell/mm3.

Conclusion: In the present study about 97.7% of febrile patients in portsudan had positives anti-dengue virus (IgM).
