写一篇英文文章，要求包括对新冠病毒的描述，传播途径，预防措施等。
The novel coronavirus, also known as COVID-19, is a highly contagious respiratory disease caused by the SARS-CoV-2 virus. COVID-19 was first identified in Wuhan, China in December 2019 and has since spread rapidly globally.

The virus spreads primarily through respiratory droplets when an infected person talks, coughs, or sneezes. Close contact with an infected person or touching a surface contaminated with the virus and then touching one's face can also lead to transmission. The incubation period for COVID-19 ranges from 2-14 days, during which an infected person can be asymptomatic or experience mild to severe symptoms such as fever, cough, and difficulty breathing.

To prevent the spread of COVID-19, individuals should practice good respiratory hygiene such as covering their mouth and nose when coughing or sneezing, washing their hands frequently with soap and water for at least 20 seconds, and avoiding close contact with individuals who are sick or displaying symptoms. Wearing masks or face coverings in public can also help reduce transmission.

In addition, social distancing measures such as staying at least 6 feet apart from others and avoiding large gatherings can also help slow the spread of the virus. Governments and health organizations have implemented measures such as travel restrictions, lockdowns, and testing and tracing programs to reduce the spread of COVID-19.

As researchers and healthcare professionals continue to study the virus and develop treatments and vaccines, it is essential for the public to remain vigilant and take necessary precautions to protect themselves and others from COVID-19.
