ABSTRACT
Background Infection breakthrough after COVID-19 vaccination is a point of conflict in current literature not only because of the estimation of the potential hazards and symptoms severity but also due to establishing a vaccination policy and measuring the extent of immunity after vaccination in addition to the waning of the humoral immunity over time. To our knowledge, this is the first study to stratify the risk of post-COVID-19 vaccination breakthroughs in Upper Egypt. Methods In this cross-sectional observational study, we enrolled 369 vaccinated patients registered in our facility either admitted or in out-patient clinic. Patients were interviewed and any proven history of COVID-19 infection after vaccination was recorded. Results In the current study, 18.97% (70 patients) of the 369 subjects enrolled in the study had COVID-19breakthrough infection. Students were the high-risk group representing 18.6% of the study subjects. Hypertension, diabetes, and cardiac disease were the most comorbidities associated with a prevalence of 15.7%, 8.6%, and 4.3% respectively. Prior to COVID-19, confirmed infection was present in 42.9% of the study group. Fever, headache, myalgia, and cough were among the most common symptoms of the post-COVID vaccination breakthrough with a prevalence of 90%, 75.7%, 84.3%, and 74.3% respectively. Conclusion Breakthrough infection after COVID-19 vaccination is not uncommon. Most cases are mild and don't require hospitalization. All types of vaccines tested in the current study offer adequate immunity and guard against severe COVID-19 infection. We encourage the current global policy of full vaccination.

ABSTRACT
Background Since being declared a global pandemic, Coronavirus disease 2019 (COVID-19) took over healthcare providers and researchers’ interest. However, other epidemic diseases, including tuberculosis (TB), are still a health issue that aggravate under the umbrella of health facilities exhaustion. This study aims to evaluate the impact of the COVID-19 pandemic on tuberculosis management. Methods A retrospective analysis of the quarterly reports issued by a tuberculosis management unit from 2017 to June 2021, including data of 12 subunits. The changes in pulmonary and extrapulmonary tuberculosis incidence trends (new + relapsed cases) throughout the 4 years were reported. The quarterly changed percentages in cases numbers along 2020 and first half of 2021 was compared with that of the same periods in 2019. Results Incidence of extrapulmonary tuberculosis was higher than pulmonary tuberculosis throughout the 4 year study periods (7.69 vs. 4.49, 9.44 vs. 4.33, 7.75 vs. 3.58, and 7.82 vs. 2.94/100.000 population, respectively) with a noticeable decline in the incidence of pulmonary TB during 2020. The second quarter of 2020 showed the lowest tuberculosis incidence rate with a 41.6% decline in the total number of diagnosed cases while 2nd quarter of 2021 showed 21.2% decline. During 2020, only 4 cases of multidrug-resistant TB were reported (compared to an average of 8 cases of MDR-TB yearly before the COVID-19 era). Conclusion There was a noticeable drop in tuberculosis case detection during the COVID-19 pandemic. The lockdown, started in Egypt by the end of March 2020, could contribute to the marked drop in the second quarter. However, a steady partial decline was continued during the first half of 2021, which foretells a growing problem.
