Diagnostic Considerations

Because of overlapping clinical and laboratory features, it may be difficult to distinguish between dengue and COVID-19 disease in endemic areas. [20] Diagnosis with one does not rule out a concomitant infection with the other, as co-infections have been reported. [21, 22, 23]

Other problems to be considered in the differential diagnosis include the following:

  • Typhoid fever
  • Shigellosis
  • Meningococcemia
  • Rickettsial infections
  • Acute leukemia
  • Idiopathic or thrombotic thrombocytopenic purpura
