Background: Oman is a high-income, low prevalent country for tuberculosis disease. although the rates have remained static over the last decade, the country is aiming for Tuberculosis (TB) elimination. Household contacts of pulmonary TB (PTB) patients form a high-risk group of susceptible individuals who could remain reservoirs of active disease. Objective: A retrospective study was conducted to estimate the prevalence of latent TB infection by Tuberculin Skin Test (TST) or Interferon-Gamma Release Assay (IGRA) screening tests among the household contacts of Omani patients with pulmonary tuberculosis. Design: A cross-sectional survey conducted between 2017 and 2018 of TB cases and their contacts in Muscat Governorate, Oman. Results: Out of the 278 contacts identified, 188 contacts fulfilled the inclusion criteria and were enrolled into the study. The prevalence of Latent Tuberculosis Infection (LTBI) was 22.8% (95% CI: 17.0 - 29.5) among household contacts. We found higher proportions of LTBI among females than males (28.7% vs. 15%, p = 0.027). Those who were exposed to Acid Fast Bacilli (AFB) smear positive cases were more likely to be LTBI (28.7% versus 15% in smear negative cases;p = 0.047). We also found an increasing trend of infection (32.3%) in the oldest age group (46 - 80 years). Conclusion: Besides children, female household contacts and older age contacts should be prioritized for screening as they are more likely to be infected and develop active disease.

Introduction: The coronavirus disease 2019 (COVID-19) was declared as pandemic by WHO by March 11th. First case reported in Oman was on 24th February 2020 and later the country went through stages of epidemic progression. This study describes the sociodemographic and epidemiological characteristics of confirmed COVID-19 cases in Muscat governorate and related outcomes. Materials and Methods: This is a descriptive, exploratory analysis of all lab confirmed COVID 19 cases that were reported from 1st February to 31st May 2020. Data for the study was primarily extracted from notifications system established for surveillance (Tarassud). Secondary data sources were, contact listings and hospital medical records. Results: 11,648 initial cases of confirmed COVID-19 infections were included. The mean age was 35 years, 84.7% (N = 9862) were males, 25.9% (N = 3017) were Omanis, and 74.1% (N = 8631) were expatriates of which Indian origin were the majority (37%). Fever and cough were the most common presentations (46.3% and 29.5% respectively). Diabetes and hypertension were the most common comorbidities (4.9% and 4.6% respectively). Hospital admission was required for 7% (N = 811) of the total reported cases, out of them 171 cases (21%) were admitted to ICU, where 107 (13.2%) were ventilated. The case fatality rate (CFR) was 0.9%. 158 clusters containing 2949 contacts were identified from case records and categorised into 3 groups based on their exposure settings. The incubation period measured was 8 days (IQR 4.0 - 15.0) for workplace, 8 days (IQR 4 - 17) for dormitory and 4 days (IQR 2.0 - 7.0) for family groups. The secondary attack rate (SAR) estimated was 41.6% (95% CI: 0.34 - 0.48), 52% (95% CI: 0.40 - 0.63) and 33% (95% CI: 0.27 - 0.38) for workplace, dormitory and family groups, respectively. Conclusion: Results of this study, determine the transmission trend of COVID-19 in a country with high immigran
