A recent study showed that 1 in 5 people who tested positive for COVID-19 had at least one gastrointestinal symptom, such as diarrhea, vomiting, or belly pain. Of those hospitalized, 25.9% had gastrointestinal issues.
Many people with COVID-19 experience gastrointestinal symptoms such as nausea, vomiting or diarrhea, sometimes prior to having fever and lower respiratory tract signs and symptoms.
In some instances, digestive symptoms are reported as the initial presentation of COVID-19 (15). These findings suggest that the virus can impair the digestive system and may explain the range of digestive symptoms seen in COVID-19, including diarrhea, nausea, vomiting, and diminished appetite (16).
Some uncommon symptoms found in COVID-19, but reported during acute illness include congestion or runny nose, skin rashes and eye issues (including conjunctivitis, eye pain and light sensitivity).
Many people with COVID-19 experience gastrointestinal symptoms such as nausea, vomiting or diarrhea, sometimes prior to developing fever and lower respiratory tract signs and symptoms.
If you have diarrhea, nausea, or vomiting, it doesn't mean that you have COVID-19. But it's wise to pay extra attention to your symptoms during this pandemic, especially if you have a health condition that raises your chances for an infection or if you live in an area where the new coronavirus is widespread.
People with COVID-19 have had a wide range of symptoms reported – ranging from mild symptoms to severe illness. Symptoms may appear 2-14 days after exposure to the virus.
Mild Illness: Individuals who have any of the various signs and symptoms of COVID-19 (e.g., fever, cough, sore throat, malaise, headache, muscle pain, nausea, vomiting, diarrhea, loss of taste and smell) but who do not have shortness of breath, dyspnea, or abnormal chest imaging.
If you have a fever, cough or other symptoms, you might have COVID-19.
The possibility of long COVID. While omicron may cause less severe symptoms, this may not mean a decreased risk of long-term sickness.
COVID-19 is a disease caused by SARS-CoV-2 that can trigger what doctors call a respiratory tract infection. It can affect your upper respiratory tract (sinuses, nose, and throat) or lower respiratory tract (windpipe and lungs).
If your stomach troubles are due to a GI bug or food poisoning, you usually should feel better within 48 hours. If you don't, call your doctor. It could be a more serious bacterial infection or an early sign of COVID-19.
Drink lots of fluids. If you have diarrhea or are vomiting, it's important to replace the lost fluids. An oral rehydration solution from the drugstore is best because it has salt and sugar that your body loses in diarrhea.
Initial presentation — Among patients with symptomatic COVID-19, cough, myalgias, and headache are the most commonly reported symptoms. Other features, including diarrhea, sore throat, and smell or taste abnormalities, are also well described (table 3).
While potential side effects of the COVID-19 vaccines include nausea and diarrhea, the likelihood of experiencing these are much lower than others.
The COVID-19 pandemic is related to self-reported increases in psychological distress and gastrointestinal symptoms among individuals with IBS and comorbid anxiety and/or depression.
CDC considers a person to have a fever when he or she has a measured temperature of 100.4° F (38° C) or greater, or feels warm to the touch, or gives a history of feeling feverish.
A high-grade fever in adults is 103 degrees F or higher.
Yes, you can have Covid (coronavirus) without a fever or with a very low-grade fever that is hardly noticeable, particularly with the Omicron variant. It is also possible to have Covid-19 with no symptoms at all and the only way you would know this is if you took a Covid-19 test.
Treatment for COVID-19 depends on the severity of the infection. For milder illness, resting at home and taking medicine to reduce fever is often sufficient. Antiviral pills such as Paxlovid or molnupiravir may be prescribed by a doctor if a patient is eligible.
Most people have mild illness and are able to recover at home.
More than 8 in 10 cases are mild. But for some, the infection gets more severe.
- The incubation period for COVID-19. Given that the incubation period can be up to 14 days, CDC recommends conducting screening testing at least weekly.
Omicron is now the most dominant strain of coronavirus in the U.S., and its incubation period may be shorter than those of previous variants. Research is just beginning. But some scientists who've studied Omicron and doctors who've treated patients with it suggest the right number might be around 3 days.
Most people with COVID-19 are no longer contagious 5 days after they first have symptoms and have been fever-free for at least three days.
