Omikron is driving the COVID-19 pandemic today. Most of the cases are caused by the sub-variant BA.5 – the most easily spreading “version” of the coronavirus to date. How much this sub-variant changed the symptoms of COVID-19 is one of the most frequently asked questions. Scientists point out three common early symptoms today. There is also an important warning.

  1. Scientists from the University of Southern California believe that the first symptom of Omicron infection is likely to be fever, as well as cough and muscle pain
  2. Subsequently, individuals are likely to experience nausea, vomiting, followed by diarrhea
  3. In some cases, gastrointestinal symptoms may be the first symptom of COVID-19 infection
  4. Experts warn patients that the severity and even the type of initial symptoms can vary greatly from person to person

Early symptoms of COVID-19 – the three most common

The COVID-19 pandemic continues to unfold. According to the World Health Organization (WHO), in the last few weeks the number of new infections has increased by 15% and the number of deaths – by 35%. The driving force of the pandemic is still the Omikron mutation (over 90% of cases – as of the end of July), of which the BA.5 sub-variant has a large share. Scientists are sure that this is not the last “version” of the coronavirus, WHO warns that more, even more infectious, may appear in the near future. As a result of all this, more and more questions are being asked about how COVID-19 symptoms have changed and how quickly they can appear.

Overall, the BA.5 sub-variant produces similar symptoms to other coronavirus mutations. Early symptoms of COVID-19 typically include fatigue, headache, sore throat, or fever, according to Johns Hopkins Medicine. Some patients also experience loss of taste or smell as an early or first symptom. However, it turns out that with BA.5 infection, the frequency of individual symptoms changes.

A study by scientists at the University of Southern California found that the first sign of infection could be fever, as well as two other symptoms: cough and muscle pain. Thereafter, sufferers are likely to experience nausea, vomiting, followed by diarrhea.

In some cases of COVID-19, digestive symptoms may be the first symptom of SARS-CoV-2 infection. Respiratory symptoms may appear one day later.

COVID-19 caused by Omikron. «There are more symptoms»

One change that researchers are paying attention to is the lower incidence of dyspnea. “In the case of Omikron, we know that the most common symptom is not shortness of breath but fever, cough and sore throat,” notes infectious disease specialist Dr. Sharon Welbel. The doctor also points out that “the symptoms people experience are very heterogeneous”.

Dr. Allison Arwady, a leading Chicago physician (commissioner of the city’s Public Health Department) also points out that the virus tends to linger in the upper respiratory tract, so symptoms may “concentrate” in this area.

Another point to which Dr. Arwady points out is the tendency to observe long-term and more widespread symptoms due to the virulence of the BA.5 sub-option. «I would say nothing significant has emerged, but there are more symptoms. It’s a more virulent infection, »she said recently.

What are the symptoms of COVID-19 today? Scientists warn

Doctors warn patients that The severity and even type of initial COVID-19 symptoms can vary greatly from person to person. “It depends on age, comorbidity, vaccination status … I think there is no way to predict this,” admits Dr. Sharon Welbel.

The Centers for Disease Control and Prevention (CDC, an agency of the US federal government, a leading global anti-epidemic organization, believe that for Omicron sub-variants, the average time to onset of symptoms can be as little as three days (typically two to 14 days after exposure to the virus). ).

How long symptoms may persist is an individual matter, depending, among others, on on the severity of the infection and possible long covid. “Some say they feel better within a day, others say their symptoms last up to three weeks,” notes Dr. Welbel.
