Estimation of the healthcare waste generation during COVID-19 pandemic in Bangladesh.

COVID-19 pandemic-borne wastes imposed a severe threat to human lives as well as the total environment. Improper handling of these wastes increases the possibility of future transmission. Therefore, immediate actions are required from both local and international authorities to mitigate the amount of waste generation and ensure proper disposal of these wastes, especially for low-income and developing countries where solid waste management is challenging. In this study, an attempt is made to estimate healthcare waste generated during the COVID-19 pandemic in Bangladesh. This study includes infected, ICU, deceased, isolated and quarantined patients as the primary sources of medical waste. Results showed that COVID-19 medical waste from these patients was 658.08 tons in March 2020 and increased to 16,164.74 tons in April 2021. A top portion of these wastes was generated from infected and quarantined patients. Based on survey data, approximate daily usage of face masks and hand gloves is also determined. Probable waste generation from COVID-19 confirmatory tests and vaccination has been simulated. Finally, several guidelines are provided to ensure the country's proper disposal and management of COVID-related wastes.

COMPARISON OF OLFACTORY DISTURBANCE IN COVID-19 POSITIVE CASES WITH NON COVID-19 RHINITIS CASES

Objective: To determine association of anosmia as an early symptom of COVID-19 infection. Study Design: Comparative cross sectional study. Place and Duration of Study: ENT department, Combined Military Hospital, Quetta, from Apr to Oct 2020. Methodology: A total of 6411 consenting patients with symptoms of viral upper respiratory tract infection presenting at ENT department, Combined Military Hospital Quetta, from Apr to Oct 2020 were tested for COVID 19 via PCR studies. Results: Out of 6411 individuals 1109 (17.3%) were found to be COVID positive and 5302 (82.7%) were COVID negative. Of the COVID positive cases 611 (55.1%) of COVID positive individuals had anosmia, whereas only 68 (1.2%) of COVID negative individuals had anosmia, this observation was statistically significant (p<0.001 on chi square test). Whereas only 33 (2.9%) patients had nasal obstruction in COVID positive group, and 68 (1.2%) cases in COVID negative group had nasal obstruction, this observation was not statistically significant (p>0.05 on chi square test). Conclusion: Anosmia has a definite association with COVID 19 infection.
