Beldomenico hypothesised that the variability in the global incidence of Covid-19 may be explained by the presence of superspreaders. Briefly, Covid-19 ‘spreads gradually within a region’ until a superspreader emerges (or is imported). Next, superspreaders not only cause a large number of transmissions; those infected by a superspreader are more likely to be superspreaders. While this hypothesis is interesting, I argue that it is extremely unlikely to be relevant in explaining Covid-19 dynamics.First, the general ‘superspreaders generate new superspreaders’ claim is not supported by the examples/references provided. In fact, it is quite clear that during the SARS outbreak in 2003 that superspreaders did not create more superspreaders, and there is absolutely no evidence for a superspreader that was ‘generated’ by a superspreader.Moreover, it follows from the ‘superspreaders generate new superspreaders’ claim that the percent of superspreaders is expected to increase with each transmission cycle. If X% of infected are superspreaders that cause many transmission events, while the other 100-X% of infected cause very few transmissions events (known as ‘the 20/80 rule’), then clearly the percent of superspreaders in each consecutive generation would increase, since by definition superspreaders cause more cases than ‘regular’ cases. However, such an increase in the proportion of superspreaders has not been reported in previous outbreaks, and is it not apparent in the current pandemic.Finally, considering that the examples of superspreaders (or more accurately superspreading events) in the context of Covid-19 are rare, and account for far less than 1% of all Covid-19 cases, which are now in the millions, such examples are likely the exception rather than the rule when it comes to Covid-19 transmission.It is critical to gain a deeper understanding of the dynamics that govern the Covid-19 pandemic, and develop effective prevention strategies against it. Part of understanding Covid-19 is defining what it is not. Based on the latest data, superspreaders are not a major driving force in the spread of Covid-19.
