The catastrophic COVID-19 pandemic has profoundly impacted every sector in the world. On March 8, Bangladesh reported first case when direct communication was impossible. As a Microbiologist I jumped to help my countrymen for diagnosis this deadly virus using very low resources, lab facilities, and PPE. In addition, I provided RT-PCR training for recent microbiology graduates, doctors, and others for the whole country, and developed COVID-19 laboratories. The terrible situation still makes me tingle since family members refrained from picking up the deceased from the hospital grounds out of concern for COVID-19. One infectious virus created an unanticipated scenario that motivated me to pursue a research career in the field of infectious disease to prevent and control such types of disease around the world. 

I collaboratively with others detected SARS-Cov-2 genetic material from both clinical and wastewater samples for predicting viral load. I communicated closely with other international researchers and used their great guidelines. We observed similar trends of viral load in wastewater and clinical samples. Further, I also extended viral surveillance project for the whole Bangladesh, and the result helped the government to predict hotspots, identify risky areas, and maintain lockdowns.  

I have supplied gold nanoparticles for the COVID-19 Rapid Kit developed by Gonoshasthaya-RNA Biotech in Bangladesh. I have also validated the RT-PCR protocol and trained RT-PCR lab personnel at Gonoshasthaya Kendra in Dhaka. l synthesized gold nanoparticles from precursor materials and performed detailed quality characterization. These locally produced, low-cost nanoparticles were used in rapid dot-blot tests for COVID-19 detection developed by the Gonoshasthaya-RNA Biotech team, helping Bangladesh respond during a time of severe shortages of test kits. Beyond his laboratory contributions, l also provided hands-on training to the Gonoshasthaya COVID-19 diagnostic team on SARS-CoV-2 detection using RT-PCR. During this period, he demonstrated strong technical skills, clear communication abilities, and effective leadership skills.

During COVID-19 I have also prepared and distributed hand sanitizer t community people. We also distributed mask and concerned people for COVID-19 spreading and maintain social distance.

The goal of this research is to create a low-cost and portable disinfection chamber that can rapidly disinfect personal clinical equipment while producing the necessary levels of ultraviolet-C radiation. Studies were carried out to evaluate its capacity to eliminate a variety of possible infections, such as the pox and severe acute respiratory syndrome associated corona viruses. Research conducted for classifying medical equipment that are at high risk of contamination due to direct contact with patients.
