Abstract

Due to the current outbreak of COVID-19, use of disinfectants and face masks had increased steeply around the globe in order to prevent the transmission of it. The objectives of this thesis include mode of action for disinfectants which have virucidal effect on COVID-19, effectiveness of negative ions disinfectant, design and effectiveness of fabric masking and nutraceutical supplementation for the treatment of COVID-19 were reviewed and discussed. All the information in this study was obtained from various electronic databases such as ProQuest, Pubmed, and SciELO by searching of the keywords ‘negative ions, disinfectants, COVID-19, copper-coated masks, Vitamin C and Vitamin D’. Based on the experiment done on efficacy test of negative ion disinfectant by exposing it to different contact times, it was shown that the longer the contact time, the greater the antibacterial activity. Besides using disinfectants to prevent the transmission of COVID-19, face masks were also crucial in controlling the pandemic. Most of the face masks available in the market were inefficient in preventing the transmission of airborne viral particles. The design and coating of copper ions onto face masks were discussed. According to papers mentioned in this thesis, copper ions can capture negatively charged infectious particles such as bacteria and viruses, halting the replication of these infectious particles and thereby preventing them from infecting us. Real-time polymerase chain reaction was carried out and the threshold cycle values (Ct values) of RdRp and E genes were not detected for copper coated mask, indicating inactivation of SARS-CoV-2 by copper ions. To decrease the rate of mortality due to COVID-19, the administration nutraceutical supplementation such as Vitamin C and Vitamin D was proven to reduce the side effect of COVID-19 infection.
