Seroprevalence of SARS-CoV-2: Insights into the epidemiology of the pandemic.

AIM: This study aimed to assess the seroprevalence of SARS-CoV-2 and disease symptoms in Malakand, Pakistan. MATERIALS & METHOD: 623 samples with suspected SARS-CoV-2 were collected from different regions of Malakand and analyzed to detect SARS-CoV-2 IgG antibodies using ELISA. RESULTS: 306 (49.1%) 0 f 623 patients were anti-SARS-CoV-2 IgG reactive, with a higher prevalence in males (75%) than females (25%). In this study, we enrolled two groups, subjects working in a non-medical setting and subjects working in a medical setting. Clinical symptoms were statistically linked with SARS-CoV-2. Four weeks of follow-up analysis of IgG titers in health care workers showed an increase in IgG antibodies titer. CONCLUSION: This study gives insights into the community-based spread of SARS-CoV-2 infection, associated immunity, and herd immunity in the studied population. This study can provide insights to the government about early vaccination of this population as most of the population is not yet vaccinated.

Knowledge, perceived risk, and attitudes towards COVID-19 protective measures amongst ethnic minorities in the UK: A cross-sectional study.

Background: Minority ethnic groups are at increased risk of COVID-19 related mortality or morbidity yet continue to have a disproportionally lower uptake of the vaccine. The importance of adherence to prevention and control measures to keep vulnerable populations and their families safe therefore remains crucial. This research sought to examine the knowledge, perceived risk, and attitudes toward COVID-19 among an ethnically diverse community. Methods: A cross-sectional self-administered questionnaire was implemented to survey ethnic minority participants purposefully recruited from Luton, an ethnically diverse town in the southeast of England. The questionnaire was structured to assess participants knowledge, perceived risk, attitudes toward protective measures as well as the sources of information about COVID-19. The questionnaire was administered online via Qualtrics with the link shared through social media platforms such as Facebook, Twitter, and WhatsApp. Questionnaires were also printed into brochures and disseminated via community researchers and community links to individuals alongside religious, community and outreach organisations. Data were analysed using appropriate statistical techniques, with the significance threshold for all analyses assumed at p = 0.05. Findings: 1,058 participants (634; 60% females) with a median age of 38 (IQR, 22) completed the survey. National TV and social networks were the most frequently accessed sources of COVID-19 related information; however, healthcare professionals, whilst not widely accessed, were viewed as the most trusted. Knowledge of transmission routes and perceived susceptibility were significant predictors of attitudes toward health-protective practises. Conclusion/recommendation: Improving the local information provision, including using tailored communication strategies that draw on trusted sources, including healthcare professionals, could facilitate understanding of risk and promote adherence to health-protective actions.

Tanneries impact on groundwater quality: a case study of Kasur city in Pakistan.

Leather industry is the second largest export-earning sector of Pakistan. However, because of poor waste management, this industry has been continuously polluting the environment. In this paper, the impact of tanneries on the groundwater quality of Kasur city (i.e., the second largest leather producing city) is examined. The study is conducted in the following three phases: (I) water samples collection, (II) determination of physio-chemical properties, and (III) application of data mining techniques. In phase I, groundwater samples were collected from various sources such as hand pumps, motor pumps, and tube wells. In phase II, several physio-chemical properties such as (i) total dissolved solids (TDS), (ii) pH, (iii) turbidity, (iv) electrical conductivity (EC), (v) total hardness (TH), (vi) total alkalinity (TA), (vii) nitrates, (viii) chromium, (ix) fluoride, and (x) chloride were estimated. The estimated values of all these foregoing parameters are then compared with the Punjab Environmental Quality Standards for Drinking Water (PEQSDW). In phase III, principle component analysis and cluster analysis of the estimated parameters were performed to elucidate the relation between various parameters and to highlight the highly vulnerable sites, respectively. The results exhibit that most of the sampling collections sites are at the threshold of losing quality water. Moreover, it is also found that Mangal Mandi carries the worst groundwater quality among all sampling locations. Overall, it is concluded that serious attention is due from the water and wastewater authorities to further investigate and monitor the groundwater quality of Kasur before the country strikes with another pandemic after COVID-19.

Seroprevalence of SARS-CoV-2 in Pakistan: an update on epidemiological trends.

The emergence of the pandemic in 2020 is a huge threat to global public health. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was first reported in China in December 2019 and later spread to almost all parts of the world in four months and declared as a pandemic in March 2020. SARS-CoV-2 has infected 15.8 million people worldwide while 641,000 died of it. This study aims to report the seroprevalence of SARS-CoV-2 in Pakistan. Of total of 635 samples of symptomatic individuals processed at Genome Center for Molecular Based Diagnostics and Research Pakistan, 313 (49.3%) were found SARS-CoV-2 seropositive. The study also confirmed more seroprevalence in elderly patients (>80 years) and children less than 13 years.

Triage of urology service to cope with COVID-19 pandemic: A single institution study.

Almost a year ago, no one has ever heard of COVID-19 but now, every individual in the world is familiar with this term. It is far from over and yet, it has affected every aspect of human life. The Department of Urology at King's College Hospital London provides all types of urology care ranging from benign to cancer treatments to the community. However, this service was badly affected by COVID-19. Policies were made by the experts in the field to reduce patient traffic in the hospital and at the same time, attempting to ensure appropriate and timely treatment was provided to patients suffering from urological conditions requiring urgent attention. In this article, we discuss the triage guidelines set up at our centre. Treatments for benign conditions such as kidney stones were delayed for 3-6 months. For the first time, telephone and video clinics were setup to follow-up patients with benign conditions. Urological emergencies such as acute urinary retention and priapism were discharged from accidental and emergency department after treatment. Small T1 renal cancers were put on surveillance, whereas T2 and T3 renal cancers were offered nephrectomy at a COVID-free specialized center. Transurethral removal of bladder tumor was offered only for solid or actively bleeding tumor. High risk prostate cancer patients were started on hormonal therapy and radiotherapy was only offered for spinal cord compression secondary to metastasis. Low and intermediate non-metastatic prostate cancers were placed on active surveillance. Patients with testicular tumor continued to have immediate inguinal orchidectomy. The multi-disciplinary meetings were done remotely using blue jeans software®. These steps not only strive to provide adequate and timely urology care to patients but also protect health care workers and prevent the spread of COVID-19.
