Yes, 37.8 degrees Celsius is considered a high temperature that could be indicative of a Covid-19 infection. According to the Centers for Disease Control and Prevention (CDC), it is important to take your temperature if you have any symptoms of Covid-19, such as a fever, cough, or shortness of breath. A temperature of 37.8 degrees Celsius or higher is considered a fever and should be reported to your healthcare provider.
In addition to taking your temperature, it is also important to look for other potential symptoms of Covid-19, such as a sore throat, loss of taste or smell, nausea, vomiting, diarrhea, muscle or body aches, fatigue, or a new headache. If you experience any of these symptoms along with a fever of 37.8 degrees Celsius or higher, you should contact your healthcare provider for further evaluation and guidance.
It is also important to remember that some people with Covid-19 may not have a fever at all. That is why it is important to stay vigilant for any other symptoms of Covid-19. If you experience any of the above symptoms, or if you have been in contact with someone who has tested positive for Covid-19, it is important to seek medical attention and get tested.
