COVID-19 symptoms

Also called: coronavirus, SARS-CoV-2

Overview

COVID-19 symptoms in current variants often resemble a bad cold or flu: sore throat, congestion, cough, fatigue, and low-grade fever. Loss of taste and smell — once nearly universal — is now less common. Most adults recover in 5–10 days.

Symptoms to watch for

  • Sore throat, congestion, runny nose
  • Cough, sometimes with chest tightness
  • Fatigue and body aches
  • Fever or chills
  • Headache
  • Loss of taste or smell (less common in newer variants)

What else could this be?

  • Flu — more abrupt fever and body aches
  • RSV — more wheezing
  • Common cold — no fever, milder
  • Strep — sore throat dominant, no cough

How it's diagnosed

Home rapid antigen tests are widely available and accurate when symptoms are present. PCR is more sensitive if you need a definitive result (e.g., for Paxlovid eligibility close to the 5-day window).

Treatment

Paxlovid (nirmatrelvir/ritonavir) reduces hospitalization risk in high-risk patients when started within 5 days of symptom onset. Otherwise: rest, fluids, acetaminophen or ibuprofen. Isolate at least 5 days and until fever-free 24 hours.

When to book a visit

Book same-day if you're over 50, immunocompromised, pregnant, or have diabetes/heart/lung disease — Paxlovid is time-sensitive.

Frequently asked

How long is COVID contagious?

Most people are contagious 1–2 days before symptoms through about 5 days after. Isolate 5 days minimum and until fever-free 24 hours without medication.

Can Clindle prescribe Paxlovid?

Yes — a licensed clinician can assess eligibility and prescribe Paxlovid during a same-day video visit when you're within the 5-day window.

Do I still need to test?

Yes if you want antivirals, to protect high-risk contacts, or to confirm return-to-work. Home antigen tests are sufficient for most decisions.
