Incubation period	Typical incubation is 2-14 days, with a median around 4-5 days.	Usually 1-3 days after exposure.
Symptom severity	Can range from mild to severe, and some cases may develop pneumonia or require hospitalization.	Usually mild, self-limiting symptoms; severe illness is uncommon in healthy individuals.
Common symptoms	Fever, persistent cough, fatigue, and sometimes loss of taste or smell.	Nasal congestion or runny nose, sore throat, sneezing, mild cough.
Fever presence	Fever is common in many cases.	Fever is less common with the common cold.
Loss of taste or smell	Often reported as altered taste or smell.	Uncommon; not typical for the common cold.
GI symptoms	Nausea or diarrhea can occur in some cases.	GI symptoms are uncommon.
Testing necessity	PCR/antigen testing is used to confirm infection.	Testing is not routinely required for diagnosing a cold; diagnosis is clinical.
Vaccination status	COVID vaccines exist and can influence risk and severity.	No vaccine exists for the common cold; prevention focuses on hygiene.
Treatment approach	Management may include monitoring and medical care if symptoms worsen; seek a clinician's advice.	Self-care at home with rest and fluids; medical care as needed and guided by a clinician.
Potential complications	Pneumonia, ARDS, and long-term symptoms (long COVID) are possible in some cases.	Complications are rare; secondary infections are possible but uncommon.
Contagious period	May be contagious before and after symptoms; contagious period varies.	Most contagious early on; contagious period is generally shorter.
Seasonality	Occurs year-round with waves of infection possible.	More common in colder months but not exclusive.
Impact on vulnerable groups	Older adults and those with comorbidities face higher risk of severe disease.	Children and healthy adults usually experience milder illness.
Mask guidance	Masking reduces spread, especially in high-risk or enclosed settings.	Mask use is common during cold season but not always required.
Vaccination relevance	Vaccination reduces risk of severe disease and hospitalization.	No vaccine for the common cold; prevention emphasizes hygiene and avoidance.
Return-to-work guidance	Isolation guidelines may apply; return depends on symptoms and policy.	Return when well enough; formal isolation not typically mandated for common cold.
Public health measures	Testing and contact tracing play a major role in outbreak control.	Public health focus is on general hygiene and surveillance during cold seasons.
Virus family	Caused by SARS-CoV-2.	Caused by rhinoviruses and other viruses.
Reinfection potential	Reinfection is possible with new variants.	Reinfections are common due to multiple cold viruses.
Test turnaround	COVID test results can take hours to days and guide actions.	Testing is not routine for cold; if performed, turnaround varies.
Long-term effects	Long COVID describes persistent symptoms after infection.	Long-term effects are uncommon after a cold.
Return-to-society impact	Outbreaks can disrupt schools, workplaces and travel.	Colds cause minor disruption; usually short-lived.
Secondary infections	Secondary bacterial infections can occur in some cases.	Secondary infections are uncommon.
Diagnostic challenges	Symptoms can overlap with other respiratory illnesses, including colds.	Overlap with other viruses means clinical assessment is common.
Public concern level	COVID often triggers higher public concern and policy actions.	Cold symptoms are usually considered routine seasonal illnesses.
Travel considerations	Travel restrictions may apply during outbreaks.	Travel may be resumed with standard precautions.
Environmental factors	Ventilation and crowding influence spread.	Ventilation and crowding also affect spread of colds.
Role of vaccination status	Vaccination status influences risk of severe disease.	Vaccination does not apply to the common cold.
Medical history relevance	Certain histories raise concern for severe outcomes.	Medical history mainly influences susceptibility to other illnesses.

What is COVID?

COVID-19 is caused by the SARS-CoV-2 virus and can vary from asymptomatic to severe illness. It spreads primarily through respiratory droplets and aerosols, and its course may be influenced by age, pre-existing conditions, and vaccination status.
