Research from Monash University on the early stages of the COVID-19 pandemic in China gives important clues into predicting the size and potential causes of second, and subsequent waves and also when restrictions can be lifted once infection rates start to decline.
The data reveal that the first 30 cases may mark a critical threshold for the transition from a slow to a fast-growing phase of the COVID-19 epidemic. Importantly, after a strict city-wide quarantine measure is applied, maintaining a high uptake of mask-wearing and reduced social contacts are essential to enable the epidemic to follow a smooth decline to elimination. However, if mask usage is 50% or less, there are likely to be more outbreaks.
