El estudio está explicado y enlazado en este artículo:
The investigators of the study
examined the 7 coronaviruses known to infect humans, focusing on the 4 that cause severe respiratory infections.
All 4 of those were found to be highly seasonal. For the past decade, the study has tracked between 890 and 1441 individuals annually, checking in with them weekly to inquire about acute respiratory infections.
“Combined over the 8 years, the number of identifications for each virus increased in December, peaked in January or February, and began to decrease in March,” Monto and colleagues wrote.
“The seasonal similarity between the 4 types is striking, with only the peak aggregate month differing between January and February.”
Sobre si habrá segunda ola, es complicado de saber. Si sigue el mismo patrón que los otros hasta diciembre no empieza a aumentar. Va a depender de cómo se transmita en el invierno del hemisferio sur. Además, deberíamos estar mucho mejor preparados esta segunda vez. Y con un porcentaje ya inmunizado.
