Coronavirus disease (COVID-19) booster doses decrease infection transmission and disease severity. This study aimed to assess the acceptance of COVID-19 vaccine booster doses in low, middle, and high-income countries of the East Mediterranean Region (EMR) and its determinants using the health belief model (HBM). In addition, we aimed to identify the causes of booster dose rejection and the main source of information about vaccination. Using the snowball and convince sampling technique, a bilingual, self-administered, anonymous questionnaire was used to collect the data from 14 EMR countries through different social media platforms. Logistic regression analysis was used to estimate the key determinants that predict vaccination acceptance among respondents. Overall, 2327 participants responded to the questionnaire. In total, 1468 received compulsory doses of vaccination. Of them, 739 (50.3%) received booster doses and 387 (26.4%) were willing to get the COVID-19 vaccine booster doses. Vaccine booster dose acceptance rates in low, middle, and high-income countries were 73.4%, 67.9%, and 83.0%, respectively (p < 0.001). Participants who reported reliance on information about the COVID-19 vaccination from the Ministry of Health websites were more willing to accept booster doses (79.3% vs. 66.6%, p < 0.001). The leading causes behind booster dose rejection were the beliefs that booster doses have no benefit (48.35%) and have severe side effects (25.6%). Determinants of booster dose acceptance were age (odds ratio (OR) = 1.02, 95% confidence interval (CI): 1.01–1.03, p = 0.002), information provided by the Ministry of Health (OR = 3.40, 95% CI: 1.79–6.49, p = 0.015), perceived susceptibility to COVID-19 infection (OR = 1.88, 95% CI: 1.21–2.93, p = 0.005), perceived severity of COVID-19 (OR = 2.08, 95% CI: 137–3.16, p = 0.001), and perceived risk of side effects (OR = 0.25, 95% CI: 0.19–0.34, p < 0.001). Booster dose acceptance in EMR is relatively high. Interventions based on HBM may provide useful directions for policymakers to enhance the population’s acceptance of booster vaccination.

Dengue epidemic in Lahore (2011) resulted in hundreds of deaths and affected thousands. As most of the studies were focused on its diagnosis and treatment, scanty data is available on associated diseases/co-morbidities in these patients that could have contributed to a higher mortality. There were no local guidelines available on recording, reporting and management of these co-morbidities. The objective of this study was to analyze the initial presentations of dengue cases and to estimate the frequency of co-morbidities in dengue patients.

Tuberculosis (TB) is a significant public health concern, and the basis of successful anti-tuberculosis treatment (ATT) rests on the complete eradication of live bacilli from a patient. This study was conducted to detect the live TB bacilli in Lowenstein Jensen culture media among exit cases of TB who were declared successfully treated, either cured or treatment completed. This cross-sectional study was conducted across Pakistan. Fifty-eight active TB DOTS centers were selected. The sample size of 3355 TB cases were equally distributed in all DOTS facilities. A detailed questionnaire was developed to record the information from TB DOTS and patients. After successful treatment, the sputum was taken from TB cases and examined to detect live bacilli on L-J culture. A total of 3355 TB cases were enrolled in the study. The male to female proportion was 1704(50.9%) and 1651(49.2%). Initially, 1993(59.4%) cases were cured, and 1362(40.6%) were declared as treatment completed cases. At exit, 324(9.65%) cases were again ZN smear-positive, and 328(9.77%) were positive on L-J culture, after being declared successfully treated for TB. To eradicate live TB bacilli, all TB cases should be subjected to L-J culture at the end of ATT.

Background: Mycobacterium tuberculosis sometimes become resistant to the drugs that are used to treat it. Drug resistant TB (DR-TB) is spread in the same way as drug susceptible TB. DR-TB is a public health crisis. This study aims to find the pattern of drug resistance and correlations between drug resistance and comorbid/non-comorbid conditions in patients with a relapse of TB. Methodology: A cross-sectional study was conducted among 200 HIV-negative relapsed TB patients from 2016-2017 in Mayo Hospital Lahore. The patients’ sputum samples were tested by Ziehl-Neelsen staining to observe acid-fast bacilli. The demographics and medical history of patients was recorded, who were positive for AFB in their sputum samples. Molecular procedure of Gene-Xpert assay was conducted to detect the presence of MTB and rifampicin resistance in the samples. Whereas, the drug susceptibility test (DST) was conducted on the LJ culture medium containing drugs.Results: Out of 200 relapsed TB cases; 97 were comorbid, 99 were non-comorbid. The most prevalent comorbidities were hypertension (42 cases- 43.3%), diabetes (45 cases-46.4%) and hepatitis B (14 cases-14.4%). Among 97 comorbid patients; 37 worked as laborers, 43 earned less than 20,000 PKR and 23 were found to have a history of imprisonment. Whereas in non-comorbid patients; 20 worked as laborers, 28 earned less than 20,000 PKR and 12 had been in prison before. The Gene-Xpert test detected rifampicin resistance (RR) in 20 comorbid (20.6%) and 33 non-comorbid (33.3%) patients. Whereas, the drug susceptibility test (DST) showed that 22 comorbid (22.7%) and 33 non-comorbid (33.3%) patients were RR. A contrast was seen in the results of Gene-Xpert and DST; Gene-Xpert detected 3 cases of RR-negative whereas the same 3 cases were found to be RR-positive on DST. Only 1 case was RR-positive on Gene-Xpert but RR-negative on DST. 17 comorbid patients (17.5%) were diagnosed with MDR-TB and 5 (5.2%) with XDR-TB. Whereas, in non-comorbid patients, there were 26 cases of MDR-TB (26.3%) and 5 cases of XDR-TB (5.1%). There were 2 patients (2.1%) resistant to all drugs.Conclusion: There was a deviation in the results of molecular Gene-Xpert assay compared to the conventional culture methods. Drug resistance was relatively higher in non-comorbid patients than comorbid patients, however, the difference between the two is not very significant.
