The novel coronavirus explained
Since the beginning of 2020, COVID-19 has caught the world’s attention, and here’s something you need to know about it.
What is a coronavirus?
Coronaviruses are a common cause of colds and other upper respiratory (呼吸的) infections in humans and certain other mammals and birds. The microbes, which get their name from the crown-like spikes (尖) on their surface, can easily spread from one animal to another. Every now and again, an animal coronavirus mutates to infect humans, leading to contagious respiratory infections that have never been met before. This makes it harder for physicians to diagnose (诊断) and cure, and results in outbreaks.
What are the symptoms of COVID-19?
The symptoms of COVID-19 are similar to those experienced when people suffer from the flu. They include fever, cough, tiredness, muscle pain and shortness of breath. Some victims have also experienced severe headaches and diarrhea.
What precautions can I take?
Coronaviruses typically pass through droplets. Therefore, scientists recommend taking simple precautions, like wearing masks, washing hands frequently and thoroughly, avoiding touching your eyes, nose, or mouth with your hands, and staying away from people displaying flu-like symptoms. Those experiencing any of the symptoms associated with the virus are advised to cover their coughs and sneezes with their inner elbows (肘). Most importantly, however, they should stay away from school, work, or any public area where they might risk infecting others.
