Background: Rates of gonorrhea are increasing across the United States. Understanding and addressing contributing factors associated with longer time to diagnosis and treatment may shorten the duration of infectiousness, which in turn may limit transmission.

Methods: We used Massachusetts data from the US Centers for Disease Control and Prevention Sexually Transmitted Disease Surveillance Network collected between July 2015 and September 2019, along with routinely reported surveillance data, to assess time from gonorrhea symptom onset to presentation to care, and time from presentation to care to receipt of treatment.

Background: Human immunodeficiency virus (HIV) preexposure prophylaxis (PrEP) reduces HIV acquisition. We used a PrEP continuum of care to measure impact of field epidemiologist-facilitated referrals for PrEP-naive infectious syphilis cases across multiple clinical and pharmacy sites of care.

Methods: Retrospective analysis of 2017 to 2018 primary and secondary syphilis cases, medical charts, and pharmacy data to identify PrEP education, referral offer, referral acceptance, first visit, prescription pickup (PrEP initiation) and 2 to 3 months (PrEP persistence).

Article Synopsis
  • The study used Massachusetts newborn screening specimens to estimate the seroprevalence of SARS-CoV-2 antibodies among mothers, which is important for public health policies.
  • It analyzed over 72,000 specimens from various towns collected between November 2019 and December 2020, correcting for testing inaccuracies through advanced statistical methods.
  • Results showed a significant increase in seroprevalence from 0.03% in November 2019 to 2.15% by December 2020, with variations across communities, highlighting that many individuals remained susceptible to the virus by the end of 2020.

Background: Directly observed therapy (DOT) is recommended for the treatment of chlamydia, however pharmacy prescriptions are frequently used. Adherence to DOT and the association between treatment method and time to treatment is unknown.

Methods: We conducted a retrospective review of a randomized 2% of laboratory-confirmed chlamydia infections reported to the Massachusetts Department of Public Health from January 1, 2019 to May 31, 2019.

Importance: Multisystem inflammatory syndrome in children (MIS-C) is associated with recent or current SARS-CoV-2 infection. Information on MIS-C incidence is limited.

Objective: To estimate population-based MIS-C incidence per 1 000 000 person-months and to estimate MIS-C incidence per 1 000 000 SARS-CoV-2 infections in persons younger than 21 years.
