Households are a significant source of SARS-CoV-2 transmission, even during periods of low community-level spread. Comparing household transmission rates by SARS-CoV-2 variant may provide relevant information about current risks and prevention strategies. This investigation aimed to estimate differences in household transmission risk comparing the SARS-CoV-2 Delta and Omicron variants using data from contact tracing and interviews conducted from November 2021 through February 2022 in five U.

The Connecticut Department of Public Health investigated characteristics associated with infection and phylogenetic relationships among cases.
Methods: A case was a SARS-CoV-2 infection diagnosed by a viral test during August 2021-September 2021 in a student.
In fall 2020, a coronavirus disease cluster comprising 16 cases occurred in Connecticut, USA. Epidemiologic and genomic evidence supported transmission among persons at a school and fitness center but not a workplace. The multiple transmission chains identified within this cluster highlight the necessity of a combined investigatory approach.

Clinical characteristics and follow-up data of MIS-C in infants have not been well described. We sought to describe the clinical course, laboratory findings, therapeutics and outcomes among infants diagnosed with MIS-C.

Our purpose was to measure trends in cervical lesions during 2008-2015 and to consider possible explanations including vaccination coverage, changes in screening for cervical cancer, and risk behaviors for acquiring HPV.
Methods: Connecticut (CT) implemented mandatory reporting of cervical intraepithelial neoplasia grades 2/3 and adenocarcinoma in situ (cervical intraepithelial neoplasia grade 2 or higher [CIN2+]) in 2008.
Foreign-born persons in the United States seeking to adjust their status to permanent resident must undergo screening for tuberculosis (TB) disease. Screening is performed by civil surgeons (CS) following technical instructions by the Centers for Disease Control and Prevention. From 2011 to 2012, 1,369 practicing CS in California, Texas, and New England were surveyed to investigate adherence to the instructions.

Vaccines that prevent infection with human papillomavirus (HPV) types 16 and 18 that are known to cause cervical cancer have been available in the United States since 2006. High-grade cervical lesions are important for monitoring early vaccine impact because they are strong surrogates for cancer yet can develop within years after infection as opposed to decades. Trends in high-grade cervical lesions including cervical intraepithelial neoplasia grades 2, 2/3, and 3 and adenocarcinoma in situ among women ages 21 to 39 years old were examined using a statewide surveillance registry in Connecticut from 2008 to 2011.

HPV type distribution was examined among women with high-grade lesions by individual and area-based measures of race, ethnicity, and poverty.
Methods: This analysis included 832 women aged 18 to 39 years reported to a surveillance registry in Connecticut during 2008 to 2010.

Knowing the human immunodeficiency virus (HIV) status of persons infected with Mycobacterium tuberculosis is important for individual treatment and preventing transmission. This evaluation analyzed surveillance data and surveyed health care providers who care for patients with HIV and tuberculosis (TB) to understand the factors contributing to suboptimal levels of Connecticut patients with TB having a known HIV status. During 2008 to 2010, 208 (76.
View Article and Find Full Text PDFBackground: Prevention of tuberculosis (TB) in the United States usually involves testing for latent tuberculosis infection (LTBI) with a tuberculin skin test (TST), followed by offering therapy to those who have a positive test result. QuantiFERON-TB Gold assay (QFT-G) is more specific for infection with Mycobacterium tuberculosis than the TST, especially among persons vaccinated with bacillus Calmette-Guérin, thereby reducing the number of false positive tests.
Methods: Adults referred to a pulmonary clinic for a positive TST result were tested with QFT-G.
Objective: To estimate racial, ethnic, and socioeconomic differences in human papillomavirus (HPV) vaccination history among women aged 18-27 years with precancerous cervical lesions diagnosed, barriers to vaccination, and timing of vaccination in relation to the abnormal cytology result that preceded the diagnosis of the cervical lesion.
Methods: High-grade cervical lesions are reportable conditions in Connecticut for public health surveillance. Telephone interviews and medical record reviews were conducted during 2008-2010 for women (n=269) identified through the surveillance registry.
In 2006, the Advisory Committee on Immunization Practices recommended that children routinely receive 2 varicella vaccine doses in place of the 1 dose previously recommended. This recommendation's initial impact on varicella epidemiology in Connecticut was assessed. Reported incidence and case-specific data were compared for 2005 and 2008.

In 1996, the source patient had pulmonary TB but completed only two weeks of treatment. From February 2005 to May 2006, the source patient lived in four different locations while contagious.

The authors also provide a review of LCMV infection, epidemiology, and public health implications. Providers should be aware of LCMV as a cause of meningitis in college students, especially those with a history of rodent exposure.

Overall, the incidence of varicella did not change during the surveillance period. Vaccination rates among reported case patients increased, and the severity of infection decreased.
