For some states, including Florida, there is a discrepancy between unexpected deaths (number of deaths more than the norm) and reported COVID deaths. The actual COVID death rate in every state is probably more than reported, but it's probably higher in Florida than some other states that tried to report accurate numbers.
I looked at the official reported deaths here
Per capita covid-19 cases and deaths
The only states with worse death tolls per capita than Florida are states that were lax in their masking and distancing mandates or were hit hard very early in the pandemic before health care figured out how to treat cases.
Among those worse than Florida:
New Mexico - had a bad outbreak early on Indian reservations combined with poor health care available on the reservations it became a catastrophe
New Jersey, New York, Pennsylvania. Massachusetts, and Rhode Island - All hit hard in April 2020 with the first big wave.
The per capita deaths in California are almost 100 / 100K better than Florida. Most of the states with low death tolls are ones that did lock down pretty thoroughly and had a chance to prepare for the storm.
If it's true Florida cooked the books and actually has more deaths per 100K than reported (which statistically is probable), then it's probably further down the list than the official numbers.
COVID appears to follow the indoor season in each part of the country. It's hitting northern states right now because this is indoor season there now because it's cold. The cold is extending further south than normal right now, but generally this is the pleasant season in the southern most states. As soon as it starts getting hot in the south and people move back indoors with the AC on, COVID will follow them.
