AbstractBackground Symptoms of Covid-19 are known to be non-specific ranging from asymptomatic cases to severe illness affecting multiple organ systems. The duration of viral RNA positivity and transmission varies in individuals. We describe the association between symptom characteristics and comorbid conditions with viral RNA positivity of SARSCoV-2 affected individuals. Methods We conducted a record-based retrospective cohort study of 179 patients found to be positive for Covid-19 in Kasaragod district in Kerala. We included details of all patients found positive during the initial phases of the pandemic and recorded details regarding symptoms, duration of viral RNA positivity and the occurrence of transmission. The data were analysed using SPSS. Results Any symptom was present in 68%. Fever (43%) was the most common symptom while 50% had at least one respiratory symptom. Increased duration of viral RNA positivity was found to be associated with presence of comorbid conditions. The majority of individuals who transmitted disease (75%) had some symptom, predominantly a respiratory symptom. Conclusion Respiratory symptoms are seen in half of the patients and viral RNA positivity was for a longer duration in patients with comorbid conditions.
