COVID-19 Symptoms Without Fever: Prevalence and Types
Fever is often highlighted as a key symptom of COVID-19, but many individuals experience the disease without developing a fever. Studies show that a significant portion of COVID-19 patients either never develop a fever or present with other symptoms first or exclusively 1467+1 MORE.
Prevalence of Non-Fever COVID-19 Cases
Research indicates that fever is present in only about 58% to 80% of COVID-19 cases, meaning a substantial number of patients do not have a fever at all 4678. In some studies focusing on mild cases, fever was observed in as few as 11.6% of patients . Additionally, a notable percentage of patients remain completely asymptomatic throughout their infection 147.
Common COVID-19 Symptoms Without Fever
Respiratory Symptoms
Cough is one of the most common symptoms in COVID-19 patients, even in the absence of fever. Studies report cough in 40% to 63% of cases, making it a frequent presenting symptom 1246+2 MORE. Other respiratory symptoms include sore throat, nasal congestion, rhinorrhea (runny nose), and shortness of breath, though these are less common 2467+1 MORE.
Loss of Smell and Taste
Loss of smell (hyposmia or anosmia) and taste (hypogeusia) are prominent symptoms that can occur without fever. In some studies, up to 39.5% of mild COVID-19 cases reported loss of smell, often accompanied by other mild symptoms like nasal congestion or runny nose 19.
Digestive Symptoms
Digestive symptoms such as diarrhea, nausea, and vomiting can be the first or only symptoms in some COVID-19 patients. Diarrhea, for example, was reported as the initial symptom in a subset of patients, and digestive symptoms are more common in those with mild disease 3567+1 MORE. These patients may not have fever at all or may develop it later.
Other Mild or Atypical Symptoms
Other symptoms that can occur without fever include fatigue, muscle aches (myalgia), headache, chest tightness, and anorexia (loss of appetite) 4678. Neurological symptoms and dermatological manifestations have also been reported, though less frequently .
COVID-19 in Children and Adolescents
In children and adolescents, fever and cough are still the most common symptoms, but a significant proportion (14.6% to 42%) are asymptomatic. Other symptoms like sore throat, headache, fatigue, and gastrointestinal issues are less common and usually occur in less than 20% of cases .
Conclusion
COVID-19 can present with a wide range of symptoms, and many patients do not experience fever. Cough, loss of smell or taste, digestive symptoms, and other mild or atypical symptoms are common, especially in mild cases or among children. Recognizing these non-fever symptoms is important for early detection and preventing the spread of the virus, as individuals without fever may still be contagious 1234+5 MORE.
