If you think you have been exposed to COVID-19 and develop a fever and symptoms, such as cough or difficulty breathing, call your healthcare provider for medical advice.
To prevent the coronavirus from spreading, the Centers for Disease Control and Prevention recommends washing hands with soap and water for at least 20 seconds or using a hand sanitizer if a sink isn’t available. The World Health Organization says people should wear face masks only if they’re sick or caring for someone who is.
“For most people, COVID-19 infection will cause mild illness; however, it can make some people very ill and, in some people, it can be fatal,” the WHO says. “Older people, and those with pre-existing medical conditions (such as cardiovascular disease, chronic respiratory disease or diabetes) are at risk for severe disease.”
The most common symptoms of COVID-19, according to the WHO: fever (in 88% of cases), dry cough (68%), fatigue (38%) and sputum/phlegm production (33%). Shortness of breath occurred in nearly 20% of cases, and about 13% had a sore throat or headache, the WHO said in a report drawing on more than 70,000 cases in China.
