WHO, CDC Recognize Risk of Virus Aerosols
It is now generally accepted that SARS-CoV-2 can be spread by aerosols as well as larger droplets from the upper respiratory tract, although the relative importance of aerosol transmission remains incompletely answered. Despite this, current UK infection control guidance for hospitals is centred on the premise that aerosols are only generated by specific medical interventions designated as aerosol generating procedures (AGPs).This draws from epidemiological observations during the 2003 outbreak of severe acute respiratory syndrome, during which certain procedures appeared to be associated with an increased risk of staff infection (particularly tracheal intubation), and these procedures had a theoretical risk of viral aerosolization.
PROBLEM
Research conducted by various scientific institutions (Among others TOHO University* in Japan and AALTO University* in Finland), show that when people continuously breath, speak, sneeze or cough an aerosol cloud is emitted. Hundreds of thousands of contagious aerosols can be generated within a few minutes. Most of the heavier droplets fall on the ground within one minute, contaminating surfaces. Micro-droplets (1/10 000 of 1 millimeter) can drift in the air for a long time, if no air movement is present. If aerosols contain a high concentration of bacteria or viruses and are inhaled for long enough, the chance of infection will increase.
Air conditioning will worsen the situation, as enforced air flow will spread contaminated aerosols evenly throughout the premises.
Keeping windows or doors open to help circulate clean air, however it's not always possible in African conditions due to extreme heat outside.
SOLUTION
UV-C rays are lethal to viruses and bacteria, as it destroys links in their DNA.
Coronavirus is an air-borne disease and the virus should be intercepted and neutralized while it's in the air. Before it reaches and contaminates surfaces or enters the human organism.
The rate of air circulation & disinfection plays a crucial role in the reduction of possible disease transfer. Despite pandemic, commercial aircrafts flying at full capacity with every seat and row occupied by passengers possess a major risk. How is that authorities world-wide are permitted 100% occupation during flights?
The answer? That the air is being constantly filtered and disinfected during flights, reducing risk the of air-borne particles flying around.
In the same way as GP's prescribe patients multiple drugs to treat illnesses, multiple devices creating multiple lines of defence can stop the virus and prevent it from spreading.
Devices to be placed/installed in “hot spots” areas, e.g. places with high chances for disease transfer.
Every device is designed to be energy efficient and will not have a significant impact on electricity bills.
