Needle and needle-containing devices should be appropriately sterilized or disposed to prevent risk of contamination or infection of individuals as a result of contact.
<h3>What is Pathogen?</h3>
This is referred to as the disease causing micro organisms and examples include bacteria, virus etc. They are present in the bodily fluids of those who are affected which is why contact with needle or other forms of sharp objects could lead to its contamination.
When sharp objects are exposed to these infectious agents, it is best to sterilize to get rid of the microbes or disposed appropriately so as to prevent the pathogens from entering into the bloodstream of another individual thereby curbing its spread.
This is therefore the reason why appropriate disposal is responsible to prevent risk of infection.

Air pollution refers to the release of pollutants into the air that are detrimental to human health and the planet as a whole.
The Clean Air Act authorizes the U.S. Environmental Protection Agency (EPA) to protect public health by regulating the emissions of these harmful air pollutants. The NRDC has been a leading authority on this law since it was established in 1970.
What Causes Air Pollution?
“Most air pollution comes from energy use and production,” says John Walke, director of the Clean Air Project, part of the Climate and Clean Air program at NRDC. “Burning fossil fuels releases gases and chemicals into the air.” And in an especially destructive feedback loop, air pollution not only contributes to climate change but is also exacerbated by it. “Air pollution in the form of carbon dioxide and methane raises the earth’s temperature,” Walke says. “Another type of air pollution is then worsened by that increased heat: Smog forms when the weather is warmer and there’s more ultraviolet radiation.” Climate change also increases the production of allergenic air pollutants including mold (thanks to damp conditions caused by extreme weather and increased flooding) and pollen (due to a longer pollen season and more pollen production).
Answer:
Since the beginning of the epidemic, 79.3 million [55.9–110 million] people have been infected with the HIV virus and 36.3 million [27.2–47.8 million] people have died of HIV. Globally, 37.7 million [30.2–45.1 million] people were living with HIV at the end of 2020.
