Coronaviruses are a large family of viruses, some causing illness in people and others circulating among animals, including camels, cats and bats. 

The 2019 novel coronavirus (COVID-19) is a new virus that causes respiratory illness in people and can spread from person-to-person. This virus was first identified during an investigation into an outbreak in Wuhan, China.

Symptoms of COVID-19 can include: 

• Fever
• Cough
• Shortness of breath 
  

The symptoms may appear in as few as two days or as long as 14 days after exposure. Reported illnesses have ranged from people with little to no symptoms to people being severely ill and dying. 

Human coronaviruses spread just like the flu or a cold:

• Through the air by coughing or sneezing;
• Close personal contact, such as touching or shaking hands;
• Touching an object or surface with the virus on it;
• Occasionally, fecal contamination.
  
  

Prevention

• Cover coughs or sneezes with your elbow. Do not use your hands!
• Wash hands often with soap and water for at least 20 seconds. Use an alcohol-based hand sanitizer if soap and water are not available.
• Clean surfaces frequently, including countertops, light switches, cell phones, remotes, and other frequently touched items.
• Contain: if you are sick, stay home until you are feeling better.
  

In addition, it is recommended that Pennsylvanians take time to prepare now. View the PA Emergency Preparedness Guide.

The CDC does not recommend wearing masks or respirators outside of workplaces settings (in the community). A respirator is a personal protective device that is worn on the face or head and covers at least the nose and mouth. Most often, spread of respiratory viruses from person-to-person happens among close contacts (within 6 feet). It is important that these devices are readily available to health care workers and others who need them.

​The CDC does not have evidence to suggest that animals or animal products imported from China pose a risk for spreading COVID-19 in the United States. This is a rapidly evolving situation and information will be updated as it becomes available.
