    Giovanetti, Marta ;
    Vazquez, Cynthia
    9 2023 | Emerg Infect Dis. 2023; 29(9):1859-1863
    The spread of Chikungunya virus is a major public health concern in the Americas. There were >120,000 cases and 51 deaths in 2023, of which 46 occurred in Paraguay. Using a suite of genomic, phylodynamic, and epidemiologic techniques, we characterized the ongoing large chikungunya epidemic in Paraguay.

  • Novel Echarate Virus Variant Isolated from Patient with Febrile Illness Chanchamayo Peru
    Novel Echarate Virus Variant Isolated from Patient with Febrile Illness, Chanchamayo, Peru
    Troncos, Gilda ;
    Popuche, Dina
    9 2023 | Emerg Infect Dis. 2023; 29(9):1908-1912
    A new phlebovirus variant was isolated from an acute febrile patient in Chanchamayo, Peru. Genome characterization and p-distance analyses based on complete open reading frames revealed that the virus is probably a natural reassortant of the Echarate virus (large and small segments) with a yet-unidentified phlebovirus (M segment).

  • Patient Characteristics During Early Transmission of SARSCoV2 Palau January 13February 24 2022
    Patient Characteristics During Early Transmission of SARS-CoV-2, Palau, January 13–February 24, 2022
    Eilers, Braiden ;
    Adelbai-Fraser, Myra D.
    9 2023 | Emerg Infect Dis. 2023; 29(9):1939-1941
    Palau had no reported evidence of COVID-19 community spread until January 2022. We chart reviewed hospitalized patients who had a positive SARS-CoV-2 test result during early community transmission. Booster vaccinations and early outpatient treatment decreased hospitalizations. Inadequate hospital infection control practices contributed to iatrogen ...

  • Interspecies Transmission of Swine Influenza A Viruses and Human Seasonal VaccineMediated Protection Investigated in Ferret Model
    Interspecies Transmission of Swine Influenza A Viruses and Human Seasonal Vaccine-Mediated Protection Investigated in Ferret Model
    van Diemen, Pauline M. ;
    Byrne, Alexander M.P.
    9 2023 | Emerg Infect Dis. 2023; 29(9):1798-1807
    We investigated the infection dynamics of 2 influenza A(H1N1) virus isolates from the swine 1A.3.3.2 (pandemic 2009) and 1C (Eurasian, avian-like) lineages. The 1C-lineage virus, A/Pavia/65/2016, although phylogenetically related to swine-origin viruses, was isolated from a human clinical case. This strain infected ferrets, a human influenza model ...

    Validation of Claims-Based Algorithm for Lyme Disease, Massachusetts, USA
    Cocoros, Noelle M. ;
    Kluberg, Sheryl A.
    9 2023 | Emerg Infect Dis. 2023; 29(9):1772-1779
    Compared with notifiable disease surveillance, claims-based algorithms estimate higher Lyme disease incidence, but their accuracy is unknown. We applied a previously developed Lyme disease algorithm (diagnosis code plus antimicrobial drug prescription dispensing within 30 days) to an administrative claims database in Massachusetts, USA, to identify ...

  • PopulationBased Serologic Survey of Vibrio cholerae Antibody Titers before Cholera Outbreak Haiti 2022
    Population-Based Serologic Survey of Vibrio cholerae Antibody Titers before Cholera Outbreak, Haiti, 2022
    Clutter, Christy H. ;
    Klarman, Molly B.
    9 2023 | Emerg Infect Dis. 2023; 29(9):1864-1867
    A Vibrio cholerae O1 outbreak emerged in Haiti in October 2022 after years of cholera absence. In samples from a 2021 serosurvey, we found lower circulating antibodies against V. cholerae lipopolysaccharide in children <5 years of age and no vibriocidal antibodies, suggesting high susceptibility to cholera, especially among young children.
