Survival of airborne virus, phage and other minute microbes. of disease. It can occur in four forms: skin, lungs, intestinal and injection. The pathogens are capable of traveling distances on air currents when they are present on either dust particles or small respiratory droplets. They occur due to the deficiencies of hormones, minerals, nutrients, and vitamins. Airborne diseases are caused by pathogens which can ride on either dust particles or small respiratory droplets that can stay suspended in the air and travel distances on air currents. Diseases can also be transmitted by a mechanical or biological vector, an animal (typically an arthropod) that carries the disease from one host to another.Mechanical transmission is facilitated by a mechanical vector, an animal that carries a pathogen from one host to another without being infected itself.For example, a fly may land on fecal matter and later transmit . Figure 1 Droplet suspension: illustration of the aerobiology of droplets and small airborne particles produced by an . Hantaviruses are transmitted to humans from the dried droppings, urine, or saliva of mice and rats. Many are capable of spreading from person to person (e.g., bloodborne pathogens and influenza viruses), either directly or indirectly; some, including Zika virus, are transmitted by insect vectors. Outdoor workers in areas with active transmission, along with those in laboratories handling samples of Zika virus, remain at the greatest risk of infection. They documented the characteristics of microbial aerosols and designed equipment and procedures to support research on the airborne transmission of respiratory diseases and the prevention of such transmission. OSHA estimates that 5.6 million workers in the health care industry and related occupations are at risk of occupational exposure to bloodborne pathogens, including human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), and others.
