This county visualization is unique to USAFacts and will be updated with the most recent data as frequently as possible. The county-level tracker makes it easy to follow COVID-19 cases on a granular level, as does the ability to break down infections per 100,000 people. States that appear in shades of green have seen declines in cases over the same period of time. Follow new cases found each day and the number of cases and deaths in Virginia. All lineages currently circulating are classified as part of the Omicron variant. In this visualization, states that appear in shades of orange have experienced a growth in new cases over the past two weeks. SARS-CoV-2 lineages with similar characteristics may affect how fast the virus spreads, the severity of illness it causes, or the effectiveness of treatments against it some of these may be classified by the World Health Organization (WHO) or the U.S. All lineages have names to help scientists talk about them. The SARS-CoV-2 virus can be mapped out similar to a family tree. As genetic changes happen over time, the virus that causes COVID-19 begins to form genetic lineages. California has over 12 million cases, followed by Texas with over 8 million, and Florida with over 7 million. What You Need to Know About Variants | View Transcript Īs a virus spreads, it has a chance to change. As of April 30, 2023, the Centers for Disease Control and Prevention (CDC) reports there have been 104,618,931 cases of COVID-19 in the United States. Those variants must be monitored more carefully. Use these charts to track how the nation is doing administering vaccinations overall or see how your state is fairing specifically.
Some variations allow the virus to spread more easily or make it resistant to treatments or vaccines. The number of Americans getting their first and second doses of the COVID-19 vaccine is growing daily. These small differences, or variants, have been studied and identified since the beginning of the pandemic. Figure 1 below shows the number and rate of COVID-19 adverse event reports by reporting period, as well as the cumulative number of reports. By comparing the branches, scientists can label them according to the differences. If you think about a virus like a tree growing and branching out, each branch on the tree is slightly different than the others. Daily new cases (7-day moving average) As states throughout the U.S.
