Are you or a loved one not feeling well? Feverish? Starting to cough?
It's hard to know what it is. Is it COVID-19? The seasonal flu? Or is it respiratory syncytial virus, also known as RSV?
All three have similar symptoms, with fever being the most common. If you want to know for sure, you can check with your health care provider. These viruses could become severe in a short span of time, so starting on the right treatment can be important.
Below is a rundown of virus symptoms and potential risks.
COVID-19 Symptoms
The good news about COVID-19 vaccines is they are effective in reducing the chances of severe disease, hospitalization, and death.
The Centers for Disease Control and Prevention, or CDC, advises that getting a COVID-19 vaccine and a booster shot when eligible are the best tools to protect you and your family against COVID-19.
People with COVID-19 report a wide range of symptoms that may appear two to 14 days after exposure to the virus. Symptoms are likely to include fever, cough, fatigue, muscle aches, headache, sore throat, and possibly a temporary loss of smell and taste. The CDC published a full list of potential COVID-19 symptoms.
"COVID-19 infection usually starts in our head. It later affects our lungs and the rest of our body," said Dr. David Hrncir, medical director, Central Vaccine Safety Hub, Defense Health Agency-Immunization Healthcare Division.
Preliminary research has shown that the Omicron variant does not spread into the lungs as aggressively as the Delta variant, which was dominant in the United States until Omicron emerged.
People who have received COVID-19 vaccines can still experience COVID-19 infections that may have symptoms similar to the common cold or flu. Patients might need testing to help confirm a diagnosis.
To help you evaluate your symptoms, the CDC has a self-tracker tool that asks demographic questions and whether you have "life-threatening symptoms that may require urgent care."
Influenza Symptoms
Influenza - better known as the flu - is also circulating. The CDC warns that the flu usually comes on suddenly, and can be more dangerous than a common cold.
