Summary -- What is already known about this topic? - Parvovirus B19 (B19) is a respiratory virus that can cause adverse fetal outcomes in pregnant women and persons who are immunocompromised or have chronic hemolytic blood disorders . After relatively low rates during the COVID-19 pandemic years of 2021–2023, B19 activity in 2024 exceeded that of prepandemic years. -- What is added by this report? - Data from the National Syndromic Surveillance Program indicated that the proportion of sera specimens positive for B19 antibodies during January–May 10, 2025, was higher than during the same period in 2024 , suggesting a sustained increase in B19 transmission. -- What are the implications for public health practice? - Health care providers should have a heightened suspicion of and consider providing testing for B19 infection among groups at high risk for severe outcomes, including pregnant women with compatible symptoms or exposure to B19. Among pregnant women, health care providers should ...

Summary - What is already known about this topic? -- Mycoplasma pneumoniae is a common cause of community-acquired pneumonia (CAP) in school-aged children . In the United States, M. pneumoniae infection prevalence decreased during the COVID-19 pandemic and remained low through 2023. - What is added by this report? -- The number of hospital discharges of children with M. pneumoniae –associated CAP from U.S. pediatric hospitals increased sharply in 2024, accounting for approximately one half of hospitalized children with CAP. This number included children aged <5 years , a group in which M. pneumoniae infections have historically been less commonly reported. Data on length of hospitalization and intensive care unit admissions indicate that M. pneumoniae infections in 2024 were not more severe than 2018–2023 infections. - What are the implications for public health practice? -- Increased awareness among health care providers might improve diagnosis and could guide treatment of M. pneum...

Most reported human cases of MERS have occurred in or near the Arabian Peninsula . Standardized clinical and epidemiologic criteria are used to determine who in the United States should be tested for MERS-CoV. In the United States , the last identified and confirmed MERS cases occurred in 2014 . -- What is added by this report? - Global reported MERS cases have declined substantially since the COVID-19 pandemic. Numbers of travelers entering the United States from in or near the Arabian Peninsula declined during the COVID-19 pandemic, but now have returned to prepandemic levels. U.S. MERS-CoV testing declined during 2017–2023 and remains low relative to prepandemic years. Clinical and epidemiologic criteria to guide U.S. testing were updated in ...
