Myth 1: In 2003, SARS went away on its own as the weather got warmer.
SARS did not die of natural causes.
It was killed by extremely intense public health interventions in mainland Chinese cities, Hong Kong, Vietnam, Thailand, Canada and elsewhere. These involved isolating cases, quarantining their contacts, a measure of “social distancing,” and other intensive efforts. These worked well for SARS because those who were most infectious were also quite ill in a distinctive way — the sick cases were the transmitters, so isolating the sick curbed transmission. In Toronto, SARS resurged after the initial wave was controlled and precautions were discontinued. This resurgence was eventually linked to a case from the first wave. The resurgence confirms that it was control measures that stopped transmission the first time.
Myth 2: The “common cold” coronaviruses are seasonal, with little transmission in the summer, so SARS-CoV-2 will be too.
Predicting how a novel virus will behave based on how others behave is always speculative, but sometimes we have to do so when we have little else to go on. So the first problem with this myth is that we don’t know whether those coronaviruses, which go by the evocative names like OC43, HKU1, 229E, and NL63, are good analogies for this virus. Still, it is worth considering the analogy especially to OC43 and HKU1, which are SARS-CoV2’s closest relatives among the seasonal coronaviruses. The other reason this is a myth is that seasonal viruses that have been in the population for a long time (like OC43 and HKU1) behave differently from viruses that are newly introduced into the population.
To understand why, it helps to understand what we know about why many respiratory viruses are winter-seasonal in temperate regions like most of the USA. Scientists have identified four factors that contribute to this phenomenon. For some viruses, we have evidence for which factors are most important, for others, we have to extrapolate.
