Can airborne viruses penetrate the skin

There are many strains of the flu, and they are constantly changing. There are drugs to treat and cure TB, although some strains of TB are drug resistant. Invasions by microorganisms are initially countered, in all vertebrates, by innate defense mechanisms that preexist in all individuals and act within minutes of infection. We will be describing the role of individual cytokines in these induced responses in the last part of this chapter. It is clear, however, that the microorganisms that a normal human being inhales or ingests, or that enter through minor wounds, are mostly held at bay or eliminated, since they seldom cause disease. In the later stages of inflammation, other leukocytes such as eosinophils and lymphocytes also enter the infected site.

Precautions that create a barrier and procedures that decrease or eliminate the microbe in the environment or on personal belongings, form the basis of interrupting transmission of direct contact diseases.

Likewise, as multi-drug-resistant variants of bacteria emerge, their UVC inactivation efficiencies are also unlikely to change greatly. If these results are confirmed in other scenarios, it follows that the use of overhead very low level far-UVC light in public locations may represent a safe and efficient methodology for limiting the transmission and spread of airborne-mediated microbial diseases. Sinus congestion, coughing and sore throats are examples of inflammation of the upper respiratory air way due to these airborne agents.

Haemophilus influenza - Invasive disease caused by Haemophilus influenzae type b can affect many organ systems. Currently, ultraviolet light is used to decontaminate surgical equipment, but the light isn't safe for human exposure.
