The Delta variant of the coronavirus has a transmission rate of 97%.

A joint research team from the World Health Organization (WHO), the London School of Hygiene and Tropical Medicine, and Imperial College London has shown that the Delta (B.1.617.2) variant of the Covid-19 coronavirus has a 97% higher transmission rate than the original variant. This transmission rate is also the highest among other new coronavirus variants.

The Kappa (B.1.617.1) variant has a 48% higher transmission rate than the original coronavirus variant. The Gamma (P.1) variant has a recorded 38% higher transmission rate.

The Alpha (B.1.1.7) and Eta (B.1.525) variants both have a 29% transmission level. The Beta (B.1.351) variant has a known 25% higher transmission rate.

The Delta, Beta, Alpha, and Gamma variants are currently categorized as variants of concern (VoC). The others are categorized as variants of interest (VoI).

The Alpha, Beta, and Delta variants have contributed to the current surge in Covid-19 cases in Indonesia. The Ministry of Health identified their presence in early May 2021. Of the three, the Delta variant is the most prevalent in the country.

To prevent the transmission of these three coronavirus variants, the public is urged to diligently implement the 3M health protocols: wearing a mask, maintaining distance, and washing hands with soap.
