Evolution and Antigenic Differentiation of Avian Influenza A(H7N9) Virus, China
Emerg Infect Dis. 2024 Apr 19;30(6). doi: 10.3201/eid3006.230530. Online ahead of print.ABSTRACTWe characterized the evolution and molecular characteristics of avian influenza A(H7N9) viruses isolated in China during 2021-2023. We systematically analyzed the 10-year evolution of the hemagglutinin gene to determine the evolutionary branch. Our results showed recent antigenic drift, providing crucial clues for updating the H7N9 vaccine and disease prevention and control.PMID:38640498 | DOI:10.3201/eid3006.230530 (Source: Emerging Infectious Diseases)

Analysis of Suspected Measles Cases with Discrepant Measles-Specific IgM and rRT-PCR Test Results, Japan
Emerg Infect Dis. 2024 Apr 5;30(5). doi: 10.3201/eid3005.231757. Online ahead of print.ABSTRACTWe investigated clinically suspected measles cases that had discrepant real-time reverse transcription PCR (rRT-PCR) and measles-specific IgM test results to determine diagnoses. We performed rRT-PCR and measles-specific IgM testing on samples from 541 suspected measles cases. Of the 24 IgM-positive and rRT-PCR--negative cases, 20 were among children who received a measles-containing vaccine within the previous 6 months; most had low IgG relative avidity indexes (RAIs). The other 4 cases were among adults who had an unknown previ...

Mpox Diagnosis, Behavioral Risk Modification, and Vaccination Uptake among Gay, Bisexual, and Other Men Who Have Sex with Men, United Kingdom, 2022
Emerg Infect Dis. 2024 Apr 4;30(5). doi: 10.3201/eid3005.230676. Online ahead of print.ABSTRACTDuring the 2022 multicountry mpox outbreak, the United Kingdom identified cases beginning in May. UK cases increased in June, peaked in July, then rapidly declined after September 2022. Public health responses included community-supported messaging and targeted mpox vaccination among eligible gay, bisexual, and other men who have sex with men (GBMSM). Using data from an online survey of GBMSM during November-December 2022, we examined self-reported mpox diagnoses, behavioral risk modification, and mpox vaccination offer and uptak...

Novel Variant and Known Mutation in 23S rRNA Gene of Mycoplasma pneumoniae, Northern Vietnam, 2023
Emerg Infect Dis. 2024 Apr 4;30(5). doi: 10.3201/eid3005.231632. Online ahead of print.ABSTRACTDuring a 2023 outbreak of Mycoplasma pneumoniae-associated community-acquired pneumonia among children in northern Vietnam, we analyzed M. pneumoniae isolated from nasopharyngeal samples. In almost half (6 of 13) of samples tested, we found known A2063G mutations (macrolide resistance) and a novel C2353T variant on the 23S rRNA gene.PMID:38573165 | DOI:10.3201/eid3005.231632 (Source: Emerging Infectious Diseases)
