Here's why some Covid numbers keep improving. Health experts say your efforts are paying off. Researchers reported Sunday that they identified seven troubling new coronavirus variants circulating in the US, according to Dr. The US shattered its records for daily new infections, hospitalizations and deaths in early January after widespread holiday gatherings and travel. Since then, Covid cases and hospitalizations have plummeted. Doctors say there are several reasons click here "One, we came off of really high numbers from the holidays," said Dr. Not herd immunitybut enough population immunity that it is causing the virus to slow down. About 14 million Americans have been fully vaccinated with both doses of their Covid vaccines.

And it takes weeks for vaccines to fully kick in. And that might contribute slightly to the decreasing Covid hospitalizations, said Dr. Jonathan Reiner, professor of medicine and surgery at George Washington University.

But Covid deaths are still painfully high. More than 42, Americans have died from Covid in just the past two weeks. The CDC has indicated that vaccine equity is an important goal, with equity defined as preferential access and administration to those who have been most affected by COVID As of November 1,47 states and Washington D. North Dakota and New Mexico are excluded from the total due to differences their reporting of data. It also shows the ratio of vaccination rates for White people compared to those of Black, Hispanic, and Asian people, as well as the percentage point difference between vaccination rates for White people and the rates for the other groups.

These data will differ from survey estimates of vaccination rates that are limited to adults.

White people had a vaccination rate that was higher than the rate for Hispanic people in 26 states, while it was similar or lower in 16 states. The size of these differences varied widely across states, and they have been narrowing over time.

Disparities in vaccination rates continued to narrow and have nearly closed for Hispanic people. Green countries are either at that point or very close to it. Yellow countries are those which could reach that point within a reasonable time frame. They still have to get lower to be green.

Red countries are either going the wrong way, staying constant, or going down very slowly. While some yellow curves might look similar to green curves, comparing the total numbers of new cases per day will often explain the differences in classification. Cases per capita is an important metric.

However, when it comes to eliminating the virus, the number of new cases per day must be zero. The fraction of the population is not what matters. If a state has new cases per day, that provides many routes for the virus to spread, regardless if the population is 1, or 10, Why are all of the peaks the same height?

These plots are adjusted for each state in order to better show the data. The vertical axis is plotted in arbitrary units, in order to easily compare the shapes of the curves. As you can see from the states which have been successful in fighting COVID, it only takes about weeks of strong interventions to get rid of the majority of cases. The data show that taking half-measures does not work.
