Ongoing Projects
FoodNet
The FoodNet project consists of active surveillance for foodborne diseases and related epidemiologic studies designed to help public health officials better understand the epidemiology of foodborne diseases in the United States.  

New Haven County Liver Study
NHCLS conducts population-based, prospective surveillance for newly diagnosed and existing cases of chronic liver disease among residents of New Haven County. Epidemiological and clinical data are used to better characterize CLD of all causes, with emphasis on infectious causes.

Lyme Disease Intervention Case-Control Study
The purpose of this case-control study is to better understand the impact of certain behaviors on Lyme disease risk in order to design more effective interventions.


Respiratory Disease Activity (RDA)
The EIP RDA is currently conducting active and passive surveillance for influenza-related hospitalizations and severe pneumonia. A vaccine efficacy case-control study evaluates the effectiveness of the influenza vaccine to prevent hospitalizations due to community-acquired influenza virus infection.
The Surveillance for Adult and Pediatric Influenza-Related Hospitalizations aims to describe clinical and epidemiologic characteristics of hospitalized patients with laboratory-confirmed influenza.
The Pediatric Influenza Vaccine Effectiveness Study aims to evaluate the overall effectiveness of the trivalent inactivated influenza vaccine in preventing hospitalization with a laboratory-confirmed, community-acquired influenza virus infection and to evaluate the possible barriers to implementation of the Advisory Committee on Immunization Practices (ACIP) recommendation for annual influenza vaccination.

 

Human Papillomavirus Vaccine Impact Monitoring Project
This project aims to monitor the impact of human papillomavirus (HPV) vaccine on cervical cancer precursors and HPV types associated with those precursors.

Completed Projects
Community Acquired Pneumonia Surveillance (CAP)
CAP was a population-based surveillance project in the greater New Haven area for community-acquired pneumonia due to emerging or reemerging infectious agents.

Ehrlichiosis Surveillance
The state-wide surveillance program for human ehrlichia infections was conducted between 1995 and 2000 in order to characterize the prevalence and annual incidence of ehrlichiosis and its spectrum of disease symptoms.  

Active Surveillance for Ehrlichiosis and Tickborne Disease
Active surveillance for human ehrlichia and babesia infections was conducted in primary care physician offices in a 12-town area around Lyme, CT. This surveillance helped document the emergence and burden of illness associated with these two emerging tickborne pathogens.  

Perinatal Group B Streptococcal Disease Prevention Demonstration Project
The objective of this project was the evaluation of current group B Streptococcal disease prevention activities in Connecticut as part of an integrated approach to perinatal infectious disease prevention.

Sentinel Surveillance for Unexplained Diarrhea Study (SSUDS)
The objectives of this multisite (CT & MD) project were to define the spectrum of agents that cause diarrheal illness in the community and to better understand modes of transmission of diarrheal illness. Learn More

Candidemia Surveillance
The objectives of this population-based, prospective surveillance project included (1) the determination of the incidence of Candida blood stream infection in the state of Connecticut and (2) definition of the risk factors for development of antifungal resistance in patients with candidemia to assess clinical outcome as a function of antifungal resistance and other factors.

Neonatal Sepsis Surveillance
The objective of this statewide surveillance program was to determine whether adoption of the perinatal antibiotic prophylaxis program to reduce the incidence of early-onset group B streptococcal disease would affect the incidence and antibiotic susceptibilities of other organisms causing sepsis and meningitis in Connecticut.

Unexplained Illness and Death Surveillance (UIDP)
UIDP is a population-based, prospective surveillance program for unexplained severe illness and death of possible infectious etiology in previously healthy residents of New Haven County.   Learn More

Unexplained Deaths Possibly Related to Bioterrorism
The Unexplained Deaths Possibly Related to Bioterrorism project was undertaken to identify patients who died in the hospital of unknown causes and to assess the degree to which diagnostic testing was performed to rule in or out the possibility of exposure to bioterrorism agents.   Learn More

Medical Examiner/ Coroner Based Surveillance for Fatal Infectious Diseases and Bioterrorism
The Medical Examiner/Coroner Based Surveillance for Fatal Infectious Diseases and Bioterrorism (Med-X) is a pathology-based syndromic surveillance system designed to recognize bioterrorism mortality and fatal infections of public health importance. 

Unexplained Pneumonia Project (UPP)

UPP aims to further characterize and understand the etiologies of severe pneumonia by collecting epidemiological and clinical data on participants as well as performing a large panel of research and diagnostic assays.
Enhanced Pneumonia Surveillance Project

EPS is a population-based surveillance study that aims to describe the demographic and epidemiological characteristics of patients admitted to New Haven City hospitals with severe pneumonia.
