Coronavirus Disease COVID 19
Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus. COVID-19 is caused by one virus, called severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2.
How (easily) does the novel coronavirus spread?
Viruses are tiny bundles of DNA or RNA which have the ability to infect host cells, hijack the machinery of the host cell and then replicate. Once the host cell’s resources are exhausted, the viral particles are released to infect other cells. In this way, the viruses ensure their survival, often at the expense of the host.
