Virol J 2021 07 3;18(1):138. Epub 2021 Jul 3.

Background: The COVID-19 pandemic is a catastrophic global phenomenon, affecting human life in a way unseen since the 1918 influenza pandemic. Effective management of this threat requires halting transmission, a strategy requiring accurate knowledge of SARS-CoV-2 transmission patterns.

Methods: This was a retrospective contact study aiming to estimate the transmission rate of COVID-19 by tracing contacts in symptomatic, pre-symptomatic, and asymptomatic patients. History of patients' contacts during 24 h before appearance of symptoms or infection confirmation was traced for disease transmission.

Results: Overall, a total of 201 COVID-19 patients had contact with 7168 people in 24 h with an average of 35.66 contacts per patient, ranging from a minimum of 4 to maximum of 87 contacts (meetings). Out of 7168 persons met, infection was detected in 64 (0.89%). For the 155 symptomatic patients, a total of 5611 contacted persons were traced before appearance of symptoms (pre-symptomatic) in last 24 h with an average of 36.20 meetings per patient. The infection was transmitted in 63 (1.12%) people with 5548 (98.88%) remaining uninfected. Out of the 63 transmissions, 62 (98.4%) were traced within 6 h before symptom onset, while only 1 was identified in the 6-12 h timeframe before symptoms. A total of 1557 persons were traced having meeting/contacts with asymptomatic cases in last 24 h before infection confirmation. Out of these 1557 persons, only 1 was found to be infected and the infection rate was calculated to be 0.06%. Statistically, the transmission rate by pre-symptomatic patients was found to be significantly higher than the transmission rate by asymptomatic individuals (P < 0.05).

Conclusion: In the studied population, the risk of pre-symptomatic and asymptomatic transmission of COVID-19 was low, with transmission risks of 1.12% and 0.06% respectively. Pre-symptomatic infection becomes very rare in contacts made longer than 6 h before onset of symptoms. The infection transmission is traced as long as about 9 h before the appearance of clear symptoms in the patients, but the incidence rate was as low as about 0.02% of the total contacts in that period.

Perception, preparedness and response of health care personals towards COVID-19 pandemic in Azad Jammu & Kashmir, Pakistan: A cross sectional interview based study.

Clin Epidemiol Glob Health 2021 Jul-Sep;11:100783. Epub 2021 Jun 1.

Saidu Medical College, Swat, KPK, Pakistan.

Objective: To assess the state of knowledge, perception, preparedness and satisfaction level of health care personals (HCPs) in Azad Jammu & Kashmir (AJK) towards COVID-19.

Study Design: It was cross sectional survey conducted by personal interviews.

Methodology: The study was conducted by interviewing 302 HCPs from 7 major district headquarter hospitals of AJK from May to September 2020. The questionnaire included 29 questions about demography, perception, training, preparedness, knowledge and awareness of HCPs about COVID-19. The data was encoded and analyzed statistically.

Results: Majority of the respondents (78.5%) believed that corona-virus is a serious health threat. However, 10.6% perceived it as a bio-weapon and 4.3% as not dangerous. About 10% of doctors were not considering it very dangerous compared to 1% of paramedics and 2.5% of the supporting staff ( = ). About 55% of the respondents showed confidence of the steps taken by government for prevention of COVID-19 while 45% had an opposite view. More than 70% of the participants had no formal training and the ratio of trained personals was significantly higher () in paramedical staff (33%) than doctors (15%). About 53% of the respondents were not satisfied with the provision of PPEs and 64% were not satisfied with their work and wages situation. Majority of the respondents (97%) were observed to follow the protocols for personal protection.

Conclusion: Majority of HCPs perceive covid-19 as a serious health concern. However, most of the HCPs are neither well trained for the current pandemic nor fully satisfied about personal protection, work load, and wages.
