As was noted, RFK Jr. commented that a "measles outbreak is not unusual," citing past year's cases. The measles "season" is still ongoing as is the current Texas outbreak so hard to say if the case counts will exceed earlier years:
2024: 285 cases of which 89% were unvaccinated or unknown
2023: 59 cases
2022: 121 cases
2021: 49 cases
2020: 13 cases
2019: 1,274 cases
Obviously Covid may have changed people's habits with respect to congregating and exposure and 2019 was the year that NYC and the Pacific Northwest had two very large outbreaks among vaccine opposed groups. So, RFK is downplaying the spread of disease at a very critical time with this specific outbreak. While many residents that are, say, 13 years and older are inoculated, and I will certainly hope that herd immunity will prevail, we have the very real, very opportunistic chance for the virus to have a lot of fun because Spring Break approaches. Yee Haw! Florida and Texas and all the ski resorts are going to be lit.
