Look at the main symptoms of the disease today

Cases of covid-19 are on the rise again in Brazil, and with so many different variants already transmitted in connection with the original virus, many wonder: What are the symptoms of this disease today? Have they changed or remained the same?

For some experts, growth may be considered a new wave of disease. Even with vaccination, it is still possible to catch certain types, especially those that are more contagious, such as microns.

In general, the way the disease manifests does not change its form – however, with the advent of omikron, sore throat has become more commonly reported as a symptom. With the arrival of winter, it may be difficult to distinguish some flu or allergy symptoms from Covid-19, but some of them remain characteristic of the disease, such as loss of smell or taste and shortness of breath.

Not everyone who is infected with Covid-19 has the same symptoms, some people may have no symptoms at all, but the most common are:

  • Fever or chills
  • Dry cough
  • Shortness of breath / shortness of breath
  • Fatigue
  • Muscle pain
  • Headache
  • Loss of smell and / or taste
  • Sore throat
  • Nasal congestion or runny nose
  • Nausea and vomiting
  • Diarrhea

Research has shown that two doses of the vaccine reduce the duration of symptoms, which is different for other diseases with similar symptoms. Another observation of the study was that patients with Omicron recover on average in a week. Also due to vaccinations, the symptoms are a bit mild.

One study found that those with omicron-type infections were more likely to have an onset of odor than those with delta seizures, and had more sore throats in patients with omikron than other types. More severe cases, which required hospitalization, were also less frequent in those who were infected with Omicron.

According to the WHO (World Health Organization), the symptoms of a serious condition include shortness of breath, loss of appetite, confusion, constant pain or chest pressure, and a temperature above 38 degrees Celsius. Other serious but less common signs are neurological complications such as irritability, loss of consciousness, anxiety, depression, sleep disturbances and stroke.

According to the CDC (US Center for Disease Control), symptoms of Covid-19 may appear two to 14 days after infection. In patients with Omicron type, symptoms may appear up to three days after infection.

Fever, fatigue, and dry cough are the most common symptoms and most often include loss of taste or smell, nasal congestion, conjunctivitis, sore throat, headache, muscle aches, acne, nausea, vomiting, diarrhea, chills, or Are associated with dizziness.

People of all ages who have symptoms of fever and cough associated with shortness of breath or difficulty breathing and chest pain should seek medical help.


It turns out that there are at least two subtypes of omicron: BA.1 and BA.2. The main difference between them is that BA.2 is more contagious and can affect younger people than BA.1.

The symptoms of the two strains seen so far are similar.

How to overcome the symptoms?

In the presence of mild symptoms, such as runny nose or sore throat, medical attention is needed, says Fernando Belisimo-Rodriguez, an infectious disease specialist and professor at Ribeirao Preto’s Faculty of Medicine at USP (University of S साo Paulo). Unnecessary.

To reduce the discomfort of these manifestations, you can use over-the-counter medications, such as diapyron or paracetamol, decongestants (unless there is a specific contraindication to this drug), cough syrups and even antiallergic medications, especially for those who have. Rhinitis, which can be decomposed by covid infection.
