Answer:
Explanation:
The virus that causes COVID-19 is not the most deadly. Ebola kills upwards of 50% of people it infects. The coronaviruses that cause Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS) result in death in about 10% of infections and between 30% to 40% of cases, respectively.
But it is a virus that has never been seen in humans, so absolutely no one is immune to it. That added to the fact that it spreads as easily from person to person as influenza, and infects the upper respiratory system, is what makes it so dangerous. Plus there is no vaccine.
Because the COVID-19 virus is found in the upper airway — including the mouth and nose — the infection can be spread through coughs, sneezes, huffing and puffing, and likely even loud talking.
Moreover, we are learning that infected people are unknowingly spreading the virus days before they begin to experience symptoms. Some may not experience symptoms at all.
Neither SARS nor MERS spread as easily or widely.
It is regarded dangerous for there is no vaccination yet for covid-19.
This disease affects homosapiens (basically humans!). Older people, and those with pre- existing medical conditions (such as high blood pressure, heart problems or diabetes) appear to be more vulnerable....
