The WHO has identified four such variants of concern: Alpha, Beta, Gamma and Delta and four variants of interest: Eta, Iota, Kappa and Lambda.Īmong the four variants of concern, Delta is believed to be the most transmissible variant yet. An increase in cases creates a greater strain on a country’s healthcare resources and may lead to more hospitalisations and deaths.

Other times, variations allow the virus to spread more easily and quickly which may lead to more cases of COVID-19. Sometimes, these new variants emerge and then disappear. Like all viruses, the SARS-CoV-2 coronavirus is evolving. Variants of concern: Alpha, Beta, Gamma and Delta.
