For most people, the new coronavirus causes only mild or moderate symptoms, such as fever and cough. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia.
The vast majority of people recover from the new virus. According to the World Health Organization, people with mild illness recover in about two weeks, while those with more severe illness may take three to six weeks to recover. In mainland China, where the virus first exploded, more than 80,000 people have been diagnosed and more than 58,000 have so far recovered.
But because the virus is new, experts can't say for sure how far it will ultimately spread. That has investors worried about a worst-case scenario for corporate profits and the economy, where factories and supply chains are shut around the world due to quarantines and people stay huddled at home instead of working or spending.
