What are the COVID-19 variations? All viruses transform over time, adjusting to their current circumstance and working on their endurance. These new strains are called variants. In May 2021, the World Health Organization (WHO) introduced a new naming system for COVID-19 Variants using letters of the Greek alphabet.

The system improves on open revealing of the strains and minimizes the discriminatory practice of naming variations after the places where they are detected. The WHO classifies Variants as variants of interest and variants of worry to focus on worldwide observing and research. Variations of interest have shown genetic changes that affec
