fewer organs and is much less severe than the original Wuhan COVID-19 virus."} 57:T494,COVID-19 can attack almost every part of the body due to several key factors:

ACE2 receptor binding: The virus has used its key—or spike protein—to bind to the angiotensin-converting enzyme 2 (ACE2) receptor, which is the gatekeeper of our cells, allowing the virus entrance.
Inflammation and cytokine storm: Once inside, the spike protein triggers inflammation, which can cause an extreme immune response (cytokine storm) that can lead to multiple organ failure.
Blood vessel damage: The spike protein can damage blood vessels, causing blood clots in vital organs that can lead to severe complications such as heart attack, stroke, and sudden death.

1. Natural Origin Theory

One of the major proposed causes of COVID-19 is rooted in a natural origin.56:{"type":"p","text":"$57"} 58:{"type":"p","text":"The virus can’t survive outside of a living organism—coronaviruses that cause severe diseases in humans usually have a natural reservoir, which is often bats. These reservoirs allow the virus to persist in nature and occasionally jump to humans or other animals, leading to outbreaks."} 59:{"type":"p","text":"However, before they can cause disease in humans, they also need an intermediate host. For example, the intermediate hosts of SARS and MERS are civets and camels, respectively."} 5a:{"type":"p","text":"
