This animation shows the infection and fatality counts for all 48 contiguous states in the U.S. and the District of Columbia, starting from January 21, 2020. It reveals the dynamic spread of COVID-19 in the U.S.
As of April 17, all states are still facing increasing infection and death at a considerable rate.
As of March 15, most states exhibited similar growth patterns in infection and death as before.
From of February 8 to February 12, most states still had similar growth patterns in infection and death as before.
From of January 8 to Feb 8, most of the states showed similar growth rate in infection and death as before.
As of January 1, 2021, most of the states still had a rapid growth rate in infection and death as before. New York, Texas, California, and Florida kept the first tier, while Illinois, New Jersey, and Pennsylvania were increasing fast in the second tier.
As of December 17, most of the states still had a fast growth rate in infection and death as before. Texas, California, and Florida are approching New York and forming the new first tier in cumulated deaths and infection counts, followed by New Jersey, and Illinois. Wyoming, Maine and Vermont have the loweest death and infection counts while Wyoming is faced with the fastest spread among them.
As of December 4, most of the states continued to grow fast in infection and death.
Throughout November, most states kept a fast growth rate in infection and death.
As of October 29, most states continued to grow fast in infection and death.
As of October 22, most states grew in the infection counts while no states exhibited abnormal changes of growth rate during last week.
As of October 15, the leading cluster of five states still kept a slow growing rate. No states experienced abnormal changes during last week.
As of October 8, there was no sudden growth for any states during last week, so most states have similar growing pattern as before.
As of October 1, most states have similar growing pattern as before. The cluster of states leading by Illinois had a slighly slower growth rate last week, so its difference from the top five states remained approximately unchanged.
As of September 24, states with high cumulative infected and fatal reports, like New York, California, Texas, Florida, Illinois, are moving with a low growth rate. States with intermediate cumulative reports, like Arizona, Louisiana, Ohio, are increasing with a relatively high rate.
As of September 17, states with high cumulative infected and fatal reports, like New York, California, Texas, Florida, Illinois, are moving with a low growth rate. New Jersey, after a very stable period, experienced a slight growth in both infected and fatal reports last week.
As of September 10, states like New York, New Jersey, Connecticut and New Hampshire are relatively stable as of the cumulative number of infected and fatal reports. Also, the cluster of states leading by Illinois is gradually moving towards the top five states. Meanwhile, California, Texas and Florida are catching up with New Jersey in the cumulative number of fatal reports.
As of August 27, New York and New Jersey are still the top 2 states of the cumulative number of infected and fatal reports, but their increasing rates are relatively small compared to other states. The cumulative numbers of infections in Texas and Florida have passed 600 thousands, approaching California.
As of August 21, we can observe the states located at the lower diagonal, with relatively higher infection, moved faster to the right upper corner. One explanation is that states that did not reach certain fatality rates have a higher potential to overgrow in both death and infection.
As of August 15, California, Texas and Florida became very similar in terms of cumulative deaths and infections. While New York has the highest deaths and infections, it is important to note that the above animation displays the cumulative counts, which in New York's cases mostly occurred at the beginning of the pandemic. It is alarming, instead, for the states which move pretty fast in the plot.
By August 5, New York still has the highest cumulative number of infected and fatal reports, followed by New Jersey. Wyoming has the least cumulative number of reported infections and deaths. The cumulative number of deaths in Montana has exceeded the cumulative number in Vermont. Vermont becomes the state with the second least cumulative number of reported infections and deaths.
During the second half of July, we can see that the infected and fatal reports in California, Texas, and Florida increase fast.
As of July 6, we can see that there are roughly five clusters of states in the above animation. New York has both the highest cumulative number of infected and fatal reports, followed by New Jersey. The third group consists of 39 states. The fourth group consists of Maine, West Virginia, North Dakota, South Dakota, and Idaho. Montana, Wyoming, and Vermont make up the last group with the least reported infections and fatalities.
By June 29, we can see that there are roughly four clusters of states in the above animation. New York has both the highest cumulative number of infected and fatal reports, followed by New Jersey. The third group consists of 44 states. Montana, Wyoming, and Vermont make up the last group with the least reported infection and fatality.
In the last week of March, New Jersey, California, and Michigan caught up with Washington. Meanwhile, all other states had a rapidly increasing number of infected and fatal cases.
Till mid-March, Washington led in both infected and fatal cases. Later, New York gained a big lead.
At the beginning of March, with the increasing reported fatality in Washington, and more and more states started gaining cases, COVID-19 caught the public eye.
Till mid-February, based on the reported infections, the disease was still endemic, while the spread was underneath.
The first infection was reported in Washington state on January 21, followed by the second in Illinois on Jan 24, third, and fourth in California on January 26. Until the end of January, the reported cases of COVID-19 in the U.S. are sporadic.
