Recently, the Ministry of Health has confirmed the presence of the Omicron variant of Covid-19 in Guatemala, increasing the number of infections during the first weeks of January 2022. However, hospitals have not reported an increase in the number of patients in intensive or moderate care. Guatemala has accumulated the highest number of Covid-19 deaths in Central America, with at least 16,263, and 669,012 confirmed cases of the disease.
Some of the factors that differentiate the Omicron variant from Covid-19 are the transmissibility and severity of the disease. A recent study published in the prestigious Journal of the American Medical Association highlights:
- Only 17.6% of patients required oxygen therapy in the 4th wave (Omicron) compared to 74% in the 3rd wave.
- Only 1.6% in the 4th wave vs. the 3rd wave. 12.4% received mechanical ventilation.
- Intensive care admission was 18.5% in wave 4 vs. 29.9% in wave 3.
These research indications are consistent with expert opinion. Although Omicron spreads more rapidly, the disease tends to be less severe than Covid-19. This is because the Omicron variant does not usually reproduce in the lungs. However, there is a possibility that this variant can develop into severe disease and even cause death, especially in unvaccinated patients.
Some differences between the symptoms of Covid-19 and the Omicron variant are:
