Flu has a lower R0 and thus is not spreading this quickly. The Flu is/was suppressed by the measures more because its lower R0 was pushed down closer to 1 which prevented any exponential expansion that is commonly happening when people don't care (i.e. don't wear masks, socialize more and are lax about washing their hands).
