On the Moon they would weigh only 200 N. The astronaut's mass is 120kg wherever they are. The weight of an object changes if the strength of gravity changes. Remember: a mass of 1 kg has a weight of about 10 N on Earth.
The droplets in the air may be breathed in by those nearby. Spread can also occur by touching the nose or mouth with droplet contaminated hands. Examples of droplet spread diseases: 1  common cold. 2  flu. 3  meningococcal disease. 4  rubella.
How Bloodborne Pathogens are Spread Training Summary. Bloodborne Pathogens are microorganisms (such as viruses) that are present in human blood and can cause disease in humans. These pathogens include, but are not limited to, hepatitis B virus (HBV), hepatitis C (HCV) and human immunodeficiency virus (HIV). The primary source of potential bloodborne pathogens is blood and specific bodily fluids. The goal is to prevent the spread of bloodborne pathogens by interrupting the way they are spread using infection control strategies.
