- Initial dengue IgG and IgM serology results might be falsely positive in the early-onset presentation of COVID-19
- Dengue fever and early onset of SARs-COV-2 infection may present with similar symptoms. Thrombocytopenia and lymphopenia are laboratory findings presented in two patients who tested positive for COVID-19 after having a false positive dengue serology result.
This data comes from an analysis in February of two patients in Singapore with false-positive serology results for dengue who tested positive, later on, for coronavirus 2 after presenting acute respiratory distress syndrome.
