COVID-19 IN PATIENTS PRESENTING WITH MALARIA-LIKE SYMPTOMS AT THE KORLE BU POLYCLINIC, ACCRA

INTRO: Malaria is one of Ghana's most frequent illnesses and the most common cause of febrile sickness. Most infectious diseases including COVID-19 and arboviral infections mimic malaria due to the overlapping of non-specific symptoms they both share.This study investigated COVID-19 in patients presenting with malaria-like symptoms at the Korle Bu Polyclinic, Accra. METHODS: This study enrolled 300 patients presenting with malaria-like symptoms aged ≤ 18. After consent was obtained from study patients, two to three millilitres of whole blood, nasopharyngeal and oropharyngeal swab samples was collected for screening of Plasmodium falciparum using malaria rapid diagnostic test, microscopy and nested PCR and SARS-CoV-2 using SARSCoV-2 antigen test and Real-time PCR respectively. The whole blood sample was also used for COVID-19 antibody test and full blood count using hematological analyser. FINDINGS: The detection of SARS-CoV-2 by COVID-19 Rapid Antigen Test and Real-time PCR were 60/300 (20%) and 26/300 (8.7%) respectively. Delta variant was reported in most SARS-CoV-2 positives with CT values below 30. The prevalence of malaria by microscopy, RDT and nested PCR were 7/300 (2.3%), 7/300 (2.3%) and 8/300 (2.7%) respectively. The most common symptom experienced by the study patients at the polyclinic was headache (95%; 57/60). Comorbidities reported were hypertension, diabetes, Asthma, hypertension and diabetes. Most of the study patients had been previously exposure to SARS CoV-2 (113/300) and 66.7% (34/51) of AstraZeneca vaccinated patients had no antibody. CONCLUSION: Due to the synergy of symptoms, screening for COVID-19 in patients presenting with malaria-like symptoms is vital for immediate diagnosis and treatment.
