The COVID-19 pandemic has brought about a multitude of questions and concerns regarding the symptoms and diagnosis of the virus. One of the most common queries is whether a body temperature of 37.2°C (98.9°F) is considered a fever in the context of COVID-19. In this article, we will delve into the relationship between body temperature and coronavirus, exploring what constitutes a fever, how COVID-19 affects body temperature, and what a temperature of 37.2°C might indicate.
What is a Fever?
A fever, also known as pyrexia, is a temporary increase in body temperature, usually above 37.2°C (98.9°F). The normal body temperature range is between 36.5°C (97.7°F) and 37.2°C (98.9°F), with an average temperature of around 36.8°C (98.2°F). When the body temperature rises above this range, it can be a sign of an underlying infection or illness.
How is Body Temperature Regulated?
The body’s temperature is regulated by the hypothalamus, a small region in the brain that acts as the body’s thermostat. The hypothalamus receives signals from temperature sensors in the skin and other parts of the body, and it responds by adjusting the body’s temperature through various mechanisms, such as sweating, shivering, and altering blood flow.
How Does COVID-19 Affect Body Temperature?
COVID-19, caused by the SARS-CoV-2 virus, can affect the body’s temperature regulation in several ways. When the virus enters the body, it triggers an immune response, which can lead to the production of pro-inflammatory cytokines. These cytokines can cause the hypothalamus to raise the body’s temperature, resulting in a fever.
What is the Typical Temperature Range for COVID-19?
Studies have shown that the typical temperature range for COVID-19 patients is between 37.3°C (99.1°F) and 39.0°C (102.2°F). However, it’s essential to note that not all COVID-19 patients develop a fever, and some may experience a low-grade fever or a temperature that is only slightly elevated.
Is 37.2 a Fever in COVID-19?
A body temperature of 37.2°C (98.9°F) is generally considered within the normal range. However, in the context of COVID-19, a temperature of 37.2°C might be considered a low-grade fever or a slightly elevated temperature.
Why Might 37.2 be Considered a Fever in COVID-19?
There are several reasons why a temperature of 37.2°C might be considered a fever in COVID-19:
- Individual variation: People’s normal body temperatures can vary, and some individuals may have a naturally higher or lower temperature than others.
- Early stages of infection: In the early stages of COVID-19, the body temperature may not be significantly elevated, and a temperature of 37.2°C might be an indication of the onset of infection.
- Mild cases: Some people with mild cases of COVID-19 may not develop a high fever, and a temperature of 37.2°C might be the highest temperature they experience.
What Does a Temperature of 37.2 Indicate in COVID-19?
A temperature of 37.2°C in COVID-19 might indicate:
- Early stages of infection: As mentioned earlier, a temperature of 37.2°C might be an indication of the onset of infection.
- Mild cases: A temperature of 37.2°C might be an indication of a mild case of COVID-19.
- Recovery: In some cases, a temperature of 37.2°C might be an indication that the body is recovering from the infection.
Conclusion
In conclusion, a body temperature of 37.2°C (98.9°F) is generally considered within the normal range. However, in the context of COVID-19, a temperature of 37.2°C might be considered a low-grade fever or a slightly elevated temperature. It’s essential to note that a temperature of 37.2°C does not necessarily indicate COVID-19, and other symptoms, such as cough, fatigue, and shortness of breath, should also be considered when diagnosing the virus.
If you’re experiencing symptoms of COVID-19, it’s crucial to consult with a healthcare professional for proper diagnosis and treatment. They will be able to assess your symptoms, perform diagnostic tests, and provide guidance on the best course of action.

Is 37.2 a Fever in Covid?
A body temperature of 37.2°C (98.9°F) is generally considered a normal temperature. However, in the context of COVID-19, a temperature of 37.2°C may be slightly elevated for some individuals, especially if they normally have a lower body temperature. The World Health Organization (WHO) defines a fever as a body temperature of 38°C (100.4°F) or higher. Therefore, 37.2°C would not be considered a fever according to this definition.
That being said, some people may experience a low-grade fever or a mild increase in body temperature during the early stages of COVID-19. If you are experiencing symptoms such as cough, fatigue, or shortness of breath, and your body temperature is 37.2°C, it is essential to monitor your temperature and seek medical attention if it rises or if your symptoms worsen.
What is the Normal Body Temperature Range?
The normal body temperature range varies from person to person, but it is generally considered to be between 36.5°C (97.7°F) and 37.5°C (99.5°F). Body temperature can fluctuate throughout the day, and it can be influenced by various factors such as age, sex, and physical activity. Some people may have a naturally higher or lower body temperature than others, and that is still considered normal.
It is essential to note that body temperature can be affected by the time of day, with temperatures tend to be higher in the late afternoon and lower in the early morning. Additionally, body temperature can be influenced by environmental factors such as ambient temperature and humidity. If you are concerned about your body temperature, it is best to consult with a healthcare professional.
How Does COVID-19 Affect Body Temperature?
COVID-19 can cause a range of symptoms, including fever, cough, and shortness of breath. A fever is a common symptom of COVID-19, and it can range from mild to severe. Some people may experience a high fever, while others may have a low-grade fever or no fever at all. The severity of the fever can vary depending on the individual and the severity of the infection.
Research has shown that people with COVID-19 tend to have a higher body temperature than those without the infection. A study published in the New England Journal of Medicine found that the average body temperature of patients with COVID-19 was 38.1°C (100.6°F), which is higher than the average body temperature of healthy individuals. However, it is essential to note that not everyone with COVID-19 will develop a fever, and the absence of a fever does not rule out the infection.
Can You Have COVID-19 Without a Fever?
Yes, it is possible to have COVID-19 without a fever. While a fever is a common symptom of COVID-19, not everyone who is infected will develop a fever. Some people may experience mild symptoms or no symptoms at all, while others may have a range of symptoms without a fever. According to the Centers for Disease Control and Prevention (CDC), some people may not develop a fever until later in the course of the illness.
It is essential to note that the absence of a fever does not rule out COVID-19. If you are experiencing symptoms such as cough, fatigue, or shortness of breath, and you have been exposed to someone with COVID-19 or have recently traveled to an area with high transmission rates, you should seek medical attention and get tested for COVID-19, even if you do not have a fever.
How Accurate Are Temperature Checks for COVID-19?
Temperature checks can be a useful tool for identifying people who may have COVID-19, but they are not foolproof. Some people may not develop a fever until later in the course of the illness, while others may have a low-grade fever that is not detectable by a temperature check. Additionally, temperature checks may not detect people who are infected with COVID-19 but are not yet showing symptoms.
According to the CDC, temperature checks should be used in conjunction with other screening measures, such as symptom checks and exposure history, to identify people who may have COVID-19. Temperature checks can be useful for identifying people who may need further evaluation or testing, but they should not be relied upon as the sole means of detecting COVID-19.
What is the Best Way to Take Your Temperature?
The best way to take your temperature is to use a digital thermometer, which can provide an accurate reading in just a few seconds. There are several types of digital thermometers available, including oral, rectal, and temporal artery thermometers. Oral thermometers are the most common type and are suitable for most adults and children.
When taking your temperature, it is essential to follow proper technique to ensure an accurate reading. This includes avoiding eating or drinking hot or cold substances for at least 30 minutes before taking your temperature, and avoiding strenuous exercise or activity. You should also make sure the thermometer is clean and calibrated correctly before use.
When Should You Seek Medical Attention for a Fever?
If you are experiencing a fever and are concerned about COVID-19, you should seek medical attention if your temperature is 38°C (100.4°F) or higher, or if you are experiencing severe symptoms such as difficulty breathing, chest pain, or severe headache. You should also seek medical attention if you have a weakened immune system or are at high risk for complications from COVID-19.
Additionally, if you are experiencing a fever and have recently traveled to an area with high transmission rates or have been exposed to someone with COVID-19, you should seek medical attention and get tested for COVID-19. It is always better to err on the side of caution and seek medical attention if you are unsure about your symptoms or risk of infection.
