COVID-19 Symptoms

What Are Some of the First Symptoms of COVID-19?

Researchers continue to study COVID-19, the brand-new coronavirus that began to strike in earnest after it first appeared in late 2019. It is particularly important for scientists to nail down the symptoms and make that information widely available to the general public. Why? If more people are able to spot the early signs of COVID-19, they can begin self-isolating sooner, when they are most contagious. Experts agree that is one of the most effective ways to minimize the spread of COVID-19, a highly infectious and dangerous virus, the long-term effects of which are still largely unknown.

Signs to Watch For

Based on what researchers have learned about COVID-19 thus far, the first symptoms—which generally occur within seven days after infection—can include the following, which are listed in order of their usual appearance:

  • Fever or chills
  • A persistent cough
  • Muscle pain
  • Nausea or vomiting
  • Diarrhea

Usually, COVID-19 symptoms are initially mild, then become more intense over the course of about seven days. With that said, it is important to understand that COVID-19 often does not produce noticeable symptoms. When it does, however, those are classic signs that should not be ignored. Additionally, some people experience:

  • Fatigue
  • Shortness of breath
  • Headache
  • A new loss of taste or smell
  • Sore throat
  • Nasal congestion or a runny nose

What to Do

If you think you might have COVID-19 and your symptoms are relatively mild, your best course of action is to stay home and separate yourself as much as possible from others in your household, including pets. Be sure to inform anyone you recently had close contact with that they may have been exposed to COVID-19 and should quarantine for 14 days. The virus can spread up to 48 hours before symptoms first appear, and after exposure, symptoms can take up to 14 days to develop.

As you recover from your illness, try to get plenty of rest and stay well hydrated. If you would like further advice, contact a healthcare provider. Consider booking a Virtual Visit so you can receive professional medical advice from the safety and comfort of your home. You may also want to inquire about COVID-19 testing. If you experience life-threatening symptoms, such as chest pain or difficulty breathing, call 911 or go directly to the nearest hospital ER.

In general, you can expect to feel better in about a week. At that time, it may be safe for you to be around others if it has been at least 10 days since your COVID-19 symptoms first appeared, you have been fever-free for at least 24 hours (without the use of fever-reducing medication), and your other symptoms are improving.

"The overall care I received was excellent! I also appreciate your affiliation with Yale New Haven Hospital."

Derby, CT

"Throughout the visit I felt like the staff really cared. The Doctor took his time talking with me about my symptoms, and I felt like he listened to all my concerns and took that into consideration when recommending the right treatment. Thank you!"

Hamden, CT

"I had to take my son in for an ear infection following a sudden change in temperament at daycare. He was inconsolable the entire car ride but when we got there and by the time we left this care facility he was back to his normal happy go lucky little two year old boy. I highly recommend PhysicianOne Urgent Care."

Westwood, MA

"I wanted to take a moment to thank you for the attention you gave me last week. My son was started on antibiotics and ear drops. Within 24 hours he began to feel better. The poor kid had been going to school in tears because he was afraid of missing any more days, but feeling (and looking) just awful! He's not been able to even think about lacrosse practice, but thanks to starting him on antibiotics, he was thrilled to return to practice today."
