A fever is a common symptom of coronavirus disease 19 (COVID-19). However, some people with the disease do not have a fever. A person may have different symptoms or none at all.
According to an April 2020 study, about
In this article, we look at the symptoms of COVID-19, how common they are, and what to do if the symptoms appear.
According to the
- a fever
- a cough
- difficulty breathing
- muscle aches
- a new loss of taste or smell
- a runny or congested nose
- a sore throat
- nausea or vomiting
Anyone can develop this illness, and its symptoms may be mild, moderate, or severe.
Also, COVID-19 can affect people differently, and some develop other, less common symptoms.
The same study that identified a fever in only
|Smell and taste disturbance||64.4|
|Dry or productive cough||60.4|
|Muscle or joint pain||44.6|
Other studies have found varying results. A July 2020 study, for example, found that
A different study from April found that out of 57,000 confirmed cases of COVID-19, only
These figures suggest that many people have COVID-19 without a fever. Additionally, according to a March 2020 report from the World Health Organization (WHO), around
COVID-19 affects people in different ways, and there can be a variety of early symptoms.
However, in research from August 2020, a team of scientists put forward a hypothesis that people develop COVID-19 symptoms in the following order:
- a fever
- muscle pain and a dry cough
- vomiting, nausea, or both
This suggests that among people who do develop a fever, it may be one of the earliest symptoms. However, proving that this order of symptoms is accurate will require further studies.
COVID-19 is a disease that stems from an infection with the virus SARS-CoV-2 — and according to the WHO, symptoms of the illness can take up to
People with mild symptoms that could indicate COVID-19 should stay at home and isolate themselves from other household members, if possible. The
- using a separate bedroom or bathroom
- avoiding contact with relatives or pets
- not sharing personal items, such as cutlery, glasses, bedding, or towels
- wearing a mask when isolation or physical distancing are not possible
Anyone with symptoms should call a doctor for advice about what to do next. It is important to mention any underlying conditions, as these may increase the likelihood of COVID-19 symptoms becoming severe.
Warning signs include:
- chest pain or pressure
- trouble breathing
- shortness of breath
- bluish lips, fingers or toes, or skin
- trouble waking up or staying awake
- new confusion
Do not visit a medical facility without calling ahead and letting the staff know that COVID-19 is a possibility.
The best way to reduce the chances of contracting SARS-CoV-2 is to prevent transmission. The CDC recommend:
- Hand washing: Wash the hands with soap and running water for at least
20 seconds. Or, when running water is unavailable, use a hand sanitizer that contains at least 60% alcohol. This is especially important:
- before touching the face, eyes, nose, or mouth
- before preparing and eating food
- after touching used tissues, masks, gloves, or other personal protective equipment
- after leaving a public place
- after using the restroom or handling a used diaper
- after blowing the nose, sneezing, or coughing
- after touching animals
- after caring for someone who is ill or may have been exposed to the virus
- Catch coughs and sneezes: Coughing or sneezing into tissues or the inside of the elbow limits how many respiratory droplets enter the air. Dispose of used tissues in designated bins and wash the hands for at least 20 seconds afterward.
- Physical distancing: Avoiding close contact with others reduces the risk of exposure to respiratory droplets that may contain SARS-CoV-2. Stay 6 feet, or 2 meters, away from others, especially in public or around people who may be sick.
- Increase cleaning and disinfecting: Clean frequently used surfaces and objects with soap and water before thoroughly using a household disinfectant. This includes objects such as:
- doorknobs, handles, and locks
- faucets and sinks
- light switches
- drawer handles
- cell phones and tablets
- keyboards and mouses
- tables and desks
- Wear a mask: A person can pass on SARS-CoV-2 even if they do not feel sick. Wearing a mask that covers the mouth and nose while around people from outside the household reduces the chances of this happening.
While a fever is commonly associated with COVID-19, many people may have the illness but no fever.
It is worth noting that when people experience COVID-19 symptoms, they tend to be mild. Anyone with any of these symptoms should take steps to isolate themselves and call a doctor for advice.
