Information about the novel coronavirus (the virus that causes COVID-19) is constantly evolving. We will refresh our novel coronavirus content weekly based on newly published peer-reviewed findings to which we have access. For the most reliable and up-to-date information, please visit the CDC website or the WHO’s advice for the public.
- Viruses are tiny infectious agents that can cause disease. Not all viruses cause disease in humans, and not all diseases are caused by viruses. The virus at the center of the current pandemic is called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
- SARS-CoV-2 is from the same family of viruses that causes the common cold, severe acute respiratory syndrome (SARS), and Middle East respiratory syndrome (MERS). SARS-CoV-2, specifically, causes coronavirus disease 2019 (COVID-19). Read more about the novel coronavirus here.
- COVID-19 is a respiratory illness with symptoms such as fever, cough, and shortness of breath. Symptoms can range from mild to severe, and the majority of patients have mild or no symptoms. Read more about coronavirus signs and symptoms here.
- COVID-19 can progress to pneumonia. In severe cases, it can lead to respiratory failure and death. Older people and people with preexisting conditions are most likely to experience the most severe symptoms. Read more about at-risk groups, here.
- Many viruses, including SARS-CoV-2, can cause symptoms of the flu, including fever and cough. While there are treatments and vaccines for the flu, we do not yet have a specific treatment or vaccine for SARS-CoV-2. Read more about the flu shot and coronavirus here.
- Symptoms of COVID-19 may not appear for days or even weeks after exposure. You can spread the virus even if you’re asymptomatic.
To ease the strain on the healthcare system and to save lives, we need to slow the spread of COVID-19 as much as we can. Here are the main ways you can do that.
- Stay home if you’re sick. To help prevent the spread of the disease, practice social distancing, which involves staying at least six feet away from everybody.
- Wear a cloth face covering in public when social distancing is difficult (such as in crowded areas). Facemasks and respirators may be in short supply and should be reserved for healthcare providers and first responders.
- Avoid large crowds of people.
- Wash your hands frequently and thoroughly.
- Have sanitizer available to wipe down surfaces and wash hands when soap and water aren’t available.
- Cough and sneeze into your elbow.
- Throw used tissues in the trash.
