@BallouxFrancois @ArisKatzourakis I don't know what you're suggesting here, since most of these waves are variant-driven and obviously spread around the world, including in opposite hemispheres.
But in any case, two years is WAY too small a sample size to meaningfully infer seasonality.
@BallouxFrancois@ArisKatzourakis我不知道你在这里建议什么，因为这些波大多数是变异驱动的，显然传播到世界各地，包括在相反的半球。
但无论如何，两年的样本量太小，无法有意义地推断季节性。
