With Covid-19 cases on the rise again in Brazil, and having spread many different variants related to the original virus, many are wondering: what are the symptoms of the disease today? Did they change or stay the same?
For some experts, the increase may be considered a new wave of disease. Even with vaccination, it is still possible to catch some variants, especially those that are more transmissible, such as microns.
Generally, these variants don’t change how the disease itself manifests — even so, with the advent of omicron, sore throats are more reported as a symptom. As winter approaches, it can be difficult to distinguish some flu or allergy symptoms from those of covid-19, but some are still typical of the disease, such as loss of smell or taste and shortness of breath.
Not everyone infected with covid-19 has the same symptoms, and some may even have no symptoms, but the most common are the following:
- fever or chills
- dry cough
- Difficulty breathing/shortness of breath
- Muscle pain
- Loss of smell and/or taste
- sore throat
- stuffy or runny nose
- nausea and vomiting
Studies have shown that two doses of the vaccine can shorten the duration of symptoms, which is also different in the case of other diseases with similar symptoms. Another observation from the study was that patients using omicron recovered within a week on average. Symptoms tend to be slightly milder because of the immune agents.
One study showed that loss of smell was less common in people infected with the omicron variant than those infected with delta, and sore throats were more common in omicron patients than in other variants. More severe cases requiring hospitalization also occurred less frequently in omicron-infected patients.
According to the World Health Organization (WHO), symptoms of severe illness include shortness of breath, loss of appetite, confusion, persistent pain or pressure in the chest and a temperature above 38°C. Other serious but less common signs are irritability, decreased consciousness, anxiety, depression, sleep disturbances, and neurological complications such as stroke.
According to the CDC (Center for Disease Control), symptoms of covid-19 can appear 2 to 14 days after infection. In patients with the omicron variant, symptoms may appear within three days of infection.
Fever, tiredness, and a dry cough are the most common symptoms and are often associated with loss of taste or smell, nasal congestion, conjunctivitis, sore throat, headache, muscle aches, rash, nausea, vomiting, diarrhea, chills, or dizziness.
People of all ages with symptoms of fever and cough associated with shortness of breath or difficulty breathing and chest pain should seek medical attention.
At least two omicron sub-variants were observed: BA.1 and BA.2. The main difference between them is that BA.2 spreads more easily than BA.1 and can affect young people.
However, the symptoms of both strains seen so far are the same.
How to relieve symptoms?
Fernando Belissimo-Rodriguez, an infectious disease expert and professor at the USP Ribeirao Preto School of Medicine, said that if mild symptoms such as a runny nose or sore throat are present, medical attention is necessary. unnecessary.
To relieve the discomfort of these manifestations, you can use over-the-counter medicines such as diphenhydramine or paracetamol, decongestants (as long as there are no specific contraindications to this medicine), cough syrups or even allergy medicines, especially for people with rhinitis , can be decompensated due to new coronavirus infection.
