CDC map shows COVID-19 cases rising in 47 U.S. states during summer surge

COVID-19 infections are increasing across most of the United States, according to the Centers for Disease Control and Prevention (CDC). The agency's latest weekly data classify transmission as "growing" or "likely growing" in 47 states, while two states are listed as "not changing" and none are reported as declining. The CDC’s tracking system does not provide exact case numbers but serves as an early indicator of trend direction.

The map shows sustained growth in several Southern states, including Texas and South Carolina, as well as Florida, North Carolina, Arkansas, Oklahoma, Alaska and Hawaii. Tennessee, Alabama and Georgia are marked as likely growing, and Louisiana and Mississippi are listed as not changing. Large metropolitan areas in California, New York, Pennsylvania and Illinois also report notable upticks.

Health officials note that severe outcomes are less common than earlier in the pandemic. > "Today it is uncommon for infection to progress to the severe stages," said Jonathan Pinsky, medical director of infection control and prevention at Endeavor Health. He added that COVID-19 still poses higher risks for older adults, the immunocompromised and people with chronic conditions.

Infectious disease physician Tyler Evans warned that a sore throat, often mistaken for allergies or a summer cold, should prompt testing, as early treatment is most effective. > "People who assume allergies do not test, and people who do not test do not get treated in the window when treatment works," he said.

Experts attribute the summer rise to waning immunity, increased indoor gatherings due to heat, travel and the return to school. > "We typically see increases in cases during the summer, when you have summer travel and then back-to-school season, and again in the winter," said Suraj Saggar, chief of infectious disease at Holy Name Medical Center in New Jersey. He cautioned that the current surge starts from a low baseline, making the absolute numbers lower than previous summer peaks.

School closures have been limited. San Perlita Independent School District in Texas and Park Ridge Achievement Academy in Louisiana each temporarily shut down campuses after COVID-19 outbreaks, citing precautionary measures.

The CDC is expected to update its epidemic trend estimates weekly as the country moves into the fall virus season. Health officials continue to advise the public to stay current with COVID-19 vaccinations and boosters, especially those at higher risk of severe disease.
