A Maryland resident who traveled to El Salvador has been diagnosed with New World screwworm. It's the first reported U.S. case tied to travel to a country with a current outbreak. The Centers for Disease Control and Prevention confirmed the diagnosis three weeks ago. Federal health officials acknowledged the infection in an emailed statement Monday. Health officials say the parasite does not spread from person to person and that the risk to the public is very low.

COVID-19 activity is rising in much of the country. Data shows overall respiratory virus spread is very low in the U.S. But COVID-19 is rising in most states, with more people of all ages going to emergency rooms because of it. The stratus variant is most common. It can cause a "razor blade" sore throat and is considered a "variant under monitoring" by the World Health Organization, but it is only marginally better at evading people's immune systems. Flu and RSV activity remain very low. Doctors say hot summer weather can drive people indoors where respiratory viruses like to spread.

COVID-19 activity is rising in much of the country. Data released Friday by federal health officials shows overall respiratory virus spread is low. But COVID-19 is rising in many states in the mid-Atlantic, the South, the southeast and on the West Coast. More people of all ages are going to emergency rooms because of COVID-19. Flu and RSV activity remain very low. Doctors say hot summer weather can drive people indoors where respiratory viruses like to spread.

Measles cases in the U.S. are at their highest in more than three decades. The U.S. Centers for Disease Control and Prevention says the U.S. has 1,288 cases since the beginning of the year. That's higher than 2019, when there 1,274 cases driven by 22 outbreaks over 12 months. Eighteen states have seen outbreaks this year. Experts fear the U.S. may lose its status as having eliminated measles. There are also large outbreaks of the vaccine-preventable disease in Mexico and Canada.

U.S. Health Secretary Robert F. Kennedy Jr.'s new vaccine advisory committee endorsed fall flu vaccinations Thursday for just about every American but with a twist: The group says people should only be given shots free of an ingredient antivaccine groups have falsely tied to autism. The seven-member panel, which includes vaccine skeptics, replaced the previous 17-member group earlier this month. Public health officials are worried that ideological decisions could make vaccines less accessible and more expensive for millions of Americans.

U.S. Health Secretary Robert F. Kennedy Jr.'s new vaccine advisory panel plans to revisit long-settled questions about childhood vaccines. On Wednesday, the new committee announced it would be looking into the childhood vaccine schedule and into specific shots like the hepatitis B and MMR-chickenpox combination. Pediatricians and scientists are expressing alarm. The American Academy of Pediatrics criticized the committee, calling its process "no longer credible." The panel also discussed COVID-19 vaccines and shots that protect infants from RSV.

The nation's top public health agency has posted new recommendations that healthy children and pregnant women may — but no longer should — get COVID-19 vaccinations. The change comes days after U.S. Health Secretary Robert F. Kennedy Jr. announced that COVID-19 vaccines will no longer recommended for healthy children and pregnant women. Kennedy announced the coming changes in a 58-second video posted on the social media site X on Tuesday. No one from the CDC was in the video, and CDC officials have referred questions about the announcement to Kennedy and the U.S. Department of Health and Human Services.

A new variant of COVID-19 is circulating in parts of the world and may be driving an increase in cases in the eastern Mediterranean, Southeast Asia and western Pacific regions. The World Health Organization said Wednesday the new variant called NB.1.8.1 is increasing globally and in mid-May had reached nearly 11% of sequenced samples. Current vaccines are expected to remain effective and there's nothing to suggest that the disease associated with the variant is more severe. Airport screening in the United States has detected the new variant in international travelers arriving in California, Washington state, Virginia and New York.

U.S. Health Secretary Robert F. Kennedy Jr. says COVID-19 vaccines are no longer recommended for healthy children and pregnant women. In a 58-second video posted on the social media site X, Kennedy said he removed COVID-19 shots from Centers for Disease Control and Prevention's recommendations for those groups. No one from the CDC was in the video. U.S. health officials, following recommendations by infectious disease experts, have been urging annual COVID-19 boosters for all Americans ages 6 months and older. A CDC scientific advisory panel is set to meets in June and will consider recommending vaccination for high-risk groups but still giving lower-risk people the choice in getting a shot. But Kennedy decided not to wait.
