Why Serotypes Data is missing?

Hello,

I visited the NOAA website dedicated to this challenge (https://dengueforecasting.noaa.gov/) and I noticed their data also included serotypes information (denv1_cases, denv2_cases, denv3_cases, denv4_cases variables).

In my opinion, this information is very important, especially to explain pandemic peaks; so why is it not included in DrivenData data sets?
