There are a number of factors associated with transmission and can be different for various pathogens but the main method of transmission for Covid-19 is AIRBORNE:

• DIRECT CONTACT: Direct contact transmission occurs through direct body contact with the tissues or fluids of an infected individual. Individuals can also be infected from touching surfaces contaminated with the virus and touching their face (e.g., eyes, nose, mouth).
• FOMITE: Fomite transmission involves inanimate objects contaminated by an infected individual that then come in contact with a susceptible animal or human.
• AIRBORNE: Aerosol transmission encompasses the transfer of pathogens via very small particles or droplet nuclei. Aerosol particles may be inhaled by a susceptible host or deposited onto mucous membranes or environmental surfaces. This can occur from breathing, coughing, sneezing, or vocalization of an infected individual, but also during certain medical procedures (e.g., suctioning, bronchoscopy, dentistry, inhalation anesthesia). Very small particles may remain suspended in the air for extended periods and be disseminated by air currents in a room or through a facility.
• ORAL: The ingestion of pathogenic organisms can occur from contaminated food or water as well as by licking or chewing on contaminated objects or surfaces. Environmental contamination is most commonly due to exudates, feces, urine, or saliva.
• VECTOR-BORNE: Vectors are living organisms that can transfer pathogenic microorganisms to other humans or animals or locations and include arthropod vectors (e.g., mosquitoes, fleas, ticks) and rodents or other vermin. Vector-borne transmission can be an important route of transmission in climates where these pests exist year-round.

Ultraviolet A (UVA) has a longer wavelength, and is associated with skin aging. Ultraviolet B (UVB) has a shorter wavelength and is associated with skin burning. UV-B causes the body to produce vitamin D, which is essential for life. Humans need some UV radiation to maintain adequate vitamin D levels. Overexposure to UV-B radiation not only can cause sunburn but also some forms of skin cancer. UV-C is the highest-energy and the most dangerous type of ultraviolet radiation, and causes effects that can variously be mutagenic or carcinogenic. As such, great care must be taken in the use of UV-C for disinfection and close human exposure is considered harmful.

UVB rays are responsible for producing sunburn. The UVB rays also play the greatest role in causing skin cancers, including the deadly black mole form of skin cancer (malignant melanoma). There are approximately 500 times more UVA rays in sunlight than UVB rays yet UVA rays have the least energy among UV rays. These rays can cause skin cells to age and can cause some indirect damage to cells' DNA. UVA rays are mainly linked to long-term skin damage such as wrinkles, but they are also thought to play a role in some skin cancers.

UVD Robots have become the gold standard for effectiveness, versatility, ease of use, and unsurpassed support worldwide. The European Commission did an extensive study on the deployment of UV-C type robots and determined that the UVD Robots stood out well above other units in all categories as evidenced by their first order of 200 units. The EU chose the UVD robot over all other forms of disinfection as, in their opinion, it provided the best certainty in disinfection because of its autonomous operations.
