On June 30, the Centers for Disease Control and Prevention added three symptoms to its COVID-19 list: Congestion/stuffy nose, nausea and diarrhea. Those three new conditions now join other symptoms identified by the CDC: Fever.
Based on what researchers have learned about COVID-19 thus far, the first symptoms—which generally occur within seven days after infection—can include the following, which are listed in order of their usual appearance: Fever or chills. A persistent cough. Muscle pain.
All of the variants, including omicron BA.5, cause similar COVID-19 symptoms: runny nose. cough. sore throat.
“Fever, cough and headache look to be the most common symptoms from the current data. However, especially if you are vaccinated and boosted, and your immune system has been primed to fight COVID-19, some people may experience minimal to no symptoms when infected with the new Omicron variant,” says Dr.
Omicron's incubation is around 3 days, compared to the 4-5 days for earlier strains. This means that if you get infected with the Delta strain, your symptoms may show up much faster. Your body will also shed the virus earlier.
Many people who are infected have more mild symptoms like a scratchy throat, stuffy or runny nose, occasional mild cough, fatigue, and no fever. Some people have no symptoms at all, but they can still spread the disease.” Fever seems to be one of the more common early markers of COVID-19, Kline noted.

a high temperature or shivering (chills) – a high temperature means you feel hot to touch on your chest or back (you do not need to measure your temperature) a new, continuous cough – this means coughing a lot for more than an hour, or 3 or more coughing episodes in 24 hours.
Like the other Omicron strains that have been dominant in the U.S. since December 2021, experts say BA. 4 and BA. 5 mainly cause cold-like symptoms and respiratory or breathing issues. The CDC reports that people's most common complaints when infected with Omicron include cough, runny nose, congestion, and fatigue.
Symptom onset
COVID-19 symptoms can be more gradual. While COVID-19 symptoms can develop as early as two days after you're infected, the Centers for Disease Control and Prevention (CDC) says five days after infection is typical.
Isolate when you test positive for COVID-19, to protect others. Day 1 is the day after symptoms start (or after the day of your first positive test if you don't have symptoms).
Antibody or serology tests look for antibodies in your blood that fight the virus that causes COVID-19. Antibodies are proteins created by your immune system after you have been infected or have been vaccinated against an infection.
Some people describe COVID sore throat as the most painful sore throat they've ever experienced. Others report a sore throat that isn't too different from one caused by a regular cold. Other COVID sore throat symptoms people notice include: Pain when swallowing or talking.
Researchers have discovered that some of the prominent features of a COVID-19 headache include: Having a pulsing, pressing, or stabbing sensation. Occurring bilaterally (across the whole head) Presenting with severe pressure that won't respond to typical pain relievers, like ibuprofen and acetaminophen.
In some people, COVID-19 causes more severe symptoms like high fever, severe cough, and shortness of breath, which often indicates pneumonia. A person may have mild symptoms for about one week, then worsen rapidly. Let your doctor know if your symptoms quickly worsen over a short period of time.
For most omicron variants in circulation today, this is one to three days, depending on the initial amount of virus you get exposed to.
The time from exposure to symptom onset (known as the incubation period) is thought to be two to 14 days. Symptoms typically appeared within five days for early variants, and within four days for the Delta variant. The incubation period appears to be even shorter – about three days – for the Omicron variant.
You are most infectious (or contagious) in the first 5 days after your symptoms start. You can also spread COVID-19 in the 48 hours before your symptoms start.
A dry cough is one of the most common coronavirus symptoms, but some people may have a cough with phlegm (thick mucus). It can be difficult to control your cough but there are a few ways to help.
Although a fever is a common symptom of this virus, it's still possible to have COVID-19 without a fever, especially within the first few days after being infected. In fact, one study found that just 55.5% of the surveyed COVID-19 patients reported experiencing a fever.
Unfortunately, yes—it is possible.
Gradually build up exercise – seize the time when you are feeling less tired and go for a short walk – but you MUST still avoid any contact with others. However, at this stage lookout for breath related symptoms (see below what to look for).
Side effects generally go away in a few days. Even if you don't experience any side effects, your body is building protection against the virus that causes COVID-19. Adverse events (serious health problems) are rare but can cause long-term health problems. They usually happen within six weeks of getting a vaccine.
