ABSTRACT
OBJECTIVE: The complete blood count (CBC) is an essential blood test that has been used for decades to assess individuals' overall health status. This study aimed to investigate the contributions of lockdown conditions to individuals' overall health status using blood indices as biological markers. During lockdown, people are limited to confined spaces, have access to limited nutritional supply options, experience increased stress, and are exposed to other environmental factors. METHODS: Our study's target population included all outpatients who were severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-negative and requested CBC assessments as part of their routine health checks. A total of 2414 CBC results were included, covering a period from February 2019 to December 2020. The average of different blood indices during the COVID-19 lockdown was compared to the 10-month period preceding the lockdown. RESULTS: The average counts of RBCs, hemoglobin, and hematocrit showed a significant increase during the lockdown period, which lasted from May 2020 to September 2020. Reductions were observed for the RBC distribution width, total white blood cell count, platelets, and platelet distribution width. CONCLUSION: Our findings suggested that the overall health status of individuals improved during the lockdown period in the short term, but health status might be adversely affected under these conditions of a longer period. Both RDW and PDW could be used as indicators for the overall health status when assessed against other blood indices.
ABSTRACT
The transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can occur through an airborne route, in addition to contaminated surfaces and objects. In hospitals, it has been confirmed by several studies that SARS-CoV-2 can contaminate surfaces and medical equipment especially in hospitals dedicated to coronavirus disease 2019 (COVID-19) patients. The aim of this study was to detect the contamination of hands, objects, and surfaces in isolation rooms and also in outpatients' clinics in hospitals and polyclinics. Environmental contamination of public high-touch surfaces in public facilities was also investigated during an active COVID-19 pandemic. Random swabs were also taken from public shops, pharmacies, bakeries, groceries, banknotes, and automated teller machines (ATMs). Samples were analyzed for SARS-CoV-2 positivity using real-time polymerase chain reaction. In the COVID-19 regional reference hospital, only 3 out of 20 samples were positive for SARS-CoV-2 RNA. Hand swabs from SARS-CoV-2-positive patients in isolation rooms were occasionally positive for viral RNA. In outpatients' clinics, door handles were the most contaminated surfaces. Dental chairs, sinks, keyboards, ophthalmoscopes, and laboratory equipment were also contaminated. Although no positive swabs were found in shops and public facilities, random ATM swabs returned a positive result for SARS-CoV-2. Although there is no longer a focus on COVID-19 wards and isolation hospitals, more attention is required to decontaminate frequently touched surfaces in health-care facilities used by patients not diagnosed with COVID-19. Additionally, high-touch public surfaces such as ATMs require further disinfection procedures to limit the transmission of the infection.
