COVID-19 Airborne Infection UV Quarantine® Method and Devices

While global attentions focus on COVID-19 immunological solutions, we believe a future possible vaccine will unexceptionally compromise to immunosenescence which will leave those older than 55 years of age inactive to any immobilization. We then validate the UV quarantine® system that shielding the UV hurt instead of segregating the contagious agents in an environment validated by 106 cell/ml E.coli DH5α spray viable colony simulation. Various experimental designs reveal that the social distancing rule should be upgraded to the “Airflow Inaccessible Distancing” code due to the undetectable small-sized infectious aerosols, saturation secondary infection from various filtering devices & quarantine spaces, and the mixing efficiency of conventional chemical sanitizers. The new code and its integrated COVID-19 Airborne Infection UV quarantine® Devices are globally the highest-efficiency systems for blocking COVID-19 from spreading under general social conditions. Portable UVC 253.7nm meters can release the safety concerns for public self-made or commercially available devices. Meanwhile, an acrylic system and relevant methods are developed to validate the performance of UV quarantine® devices and conventional masks under real applications. Also, a 33 % placebo infection rate is suggested as the minimum requirement for Phase 3 clinical trials of all medical devices, vaccines, or drugs intended for COVID-19 due to the existence of human respiratory rhyme and the weakness of nasal turbinates in blocking infection transmission via body HuNAb increase. And base on such a placebo infection rate, it is recommended to use intervention with over 99% block efficiency that equivalent to a lockdown to control the pandemic at the population level.
