Frequency of Covid-19 in Population of District Nowshera, Pakistan

Corona Virus disease termed as COVID-19 is an emerging highly contagious respiratory disease that is caused by novel corona virus 2019nCoV. To understand the basic mechanism of rapid transmission of this menace we have to develop the database to know the ratio of positivity of the disease among the asymptomatic, symptomatic patients and in patients with history of travel to an infected area or contact with positive COVID-19 patients. Based on the above concept valuing the clinical presentation, proper history taking to reach a clinical diagnosis of the disease among the strong suspects, we did a clinical intervention to determine the ratio of viral infectivity in our population. We observed that 114 (18.1%) case out of 629 suspects attended the COVID-19 clinic or followed after the positive cases including their close contacts or family members of the COVID-19 Positive. When the same ratio was determined in strong suspects where only the patients who were tested through nasophayngeal swabs for 2019-nCoV PCR, we observed that 114 (29.6%) out of 385 were confirmed positive. There was a significant relationship of viral infectivity with an increase in age (p=0.006). Hence we concluded that a higher proportion of the suspects and patients with close contacts with infected patients are positive irrespective of the clinical presentation.
