Key points:

  • Can I still get infected even if I’m fully vaccinated?
  • Do symptoms differ from one variant to another?
  • What factors could make the illness more severe?

Given the recent global concern over the new Omicron variant of COVID-19, it’s important to get an initial overview of what this viral mutation could mean for humanity.

While we know from early published medical data that this new variant has a high transmission rate, it’s worth noting the importance of completing the full vaccination schedule, which has proven highly effective in reducing illness severity in the population.

Various factors increase the severity of illness and even the mortality rate across any variant, such as chronic conditions, untreated health issues, or patients with comorbidities.

As for the specific symptoms seen in patients infected with Omicron, they may experience a runny nose, cough, sore throat, headache, and body aches. It’s worth noting that people who have already had COVID-19 may still be susceptible to this new variant, as are those who haven’t received any vaccine doses.

For this reason, the medical community has pointed out that a third dose, as a preventive booster, is key to protecting ourselves, given the uncertainty surrounding this mutation, while also emphasizing the importance of maintaining safety protocols:

  • Wearing a mask that covers the mouth and nose.
  • Practicing hand hygiene and avoiding touching the eyes, nose, and mouth.
  • Practicing social distancing and avoiding crowded places.
  • Keeping spaces well-ventilated and maintaining safe distances.
