August 29, 2017 |Vaccination Myths and Facts

According to the Centers for Disease Control and Prevention (CDC), vaccinations that help protect children from infectious diseases have saved hundreds of thousands of lives in the U.S. and prevented millions of hospitalizations over the years. But there is so much confusing information online about vaccines for children that it can be tough to know what's true and what's not, reports Consumer Reports. The CDC recommends a vaccination schedule for children. Addressing the myth that it’s safer to space out kids' vaccines, Wilbert van Panhuis, MD, PhD, an assistant professor of epidemiology at the University of Pittsburgh, responds, "The CDC bases the schedule on disease risks and vaccine effectiveness at specific ages, and the way vaccines may interact with each other. To start mixing this up is really complicated and actually can be dangerous" possibly leaving kids vulnerable to infectious diseases. Read more.

February 15, 2017 |Project Tycho Introduced to Indian Health Researchers

In December 2016, the Public Health Dynamics Laboratory (PHDL) at the University of Pittsburgh Graduate School of Public Health hosted a one-week workshop titled "Empowering Indian Health Researchers with Computational Modeling Tools". Six researchers from India participated in the workshop, a collaboration between SHARE INDIA/MediCiti Institute of Medical Sciences, the Indian Institute of Public Health, Hyderabad, and the Graduate School of Public Health, University of Pittsburgh.

The workshop was designed to train Indian researchers in simulation and modeling and other tools developed by the PHDL. In addition to the hands-on-training in the use and application of FRED (Framework for Reconstructing Epidemiological Dynamics), an open source modeling system developed by the PHDL, Dr. Wilbert van Panhuis provided an introduction to Project Tycho.

February 15, 2017 |Project Tycho Featured at Infectious Diseases & Microbiology Seminar Series

Dr. Wilbert van Panhuis, lead investigator for Project Tycho and Assistant Professor of Epidemiology, University of Pittsburgh Graduate School of Public Health, was the guest speaker at the January 30th Infectious Diseases and Microbiology (IDM) Seminar Series at Pitt Public Health. Dr. Van Panhuis spoke on "Data integration to counter epidemic threats: Computational models of vector-born diseases".

The talk focused on how many valuable datasets are not being used to counter epidemic threats due to challenges in accessing and standardizing datasets, and in integrating data into novel analyses such as epidemic simulation. The Project Tycho team aim to improve the acquisition, standardization, and integration of information about epidemic threats. Dr. Van Panhuis discussed the following examples: 1) Data on dengue fever from eight countries in Southeast Asia found that synchronous dengue transmission in this region coincided with elevated temperatures caused by El Niño; 2) data integrated for an agent-based simulation model of Chikungunya in Colombia, representing 45 million people in over 10 million households, schools, and workplaces, found that information about previous dengue outbreaks can help target mosquito control against Chikungunya. The current aim is to make data and epidemic simulation models easier to use and re-use by researchers and policy makers.

March 9, 2016 |Project Tycho® Data Used to Study US and UK Measles Epidemics

periodicityMeasles epidemics continue to pose a significant public health risk wherever vaccination coverage is low. In a paper published in the PLoS Computational Biology, February 2016, researchers used Project Tycho® data to compare 20-year measles incidence time series in 80 major cities during the prevaccination era. Forty of these cities were located in the US and 40 in the UK. Results showed that slight changes in the seasonal pattern of measles transmission caused by differences in the length of school holidays can lead to chaotic patterns, reducing the capacity to forecast epidemics and to determine the efficacy of control strategies.


February 10, 2016 |Published Findings Presented at Pitt Seminar

Sourya ShresthaOn January 11, 2016, Dr. Sourya Shrestha from Johns Hopkins University was the guest speaker at the 2015-2016 Public Health Dynamics Laboratory (PHDL) Seminar Series at the University of Pittsburgh. Dr. Shrestha spoke on the findings published in Nature Scientific Reports, October 21, 2015, on the role of influenza in the epidemiology of pneumonia. He employs modeling techniques rooted in applied mathematics and infectious disease ecology, along with epidemiological data to understand transmission dynamics of infectious diseases such as pneumonia, tuberculosis and dengue. He uses multiple sources of epidemiological data, including Project Tycho® data, which vary in the time periods they cover and the scales at which they are collected, and a mechanistic transmission model, both within a likelihood-based inference framework to characterize the nature, timing, and magnitude of this interaction. In this paper, they concluded that influenza infection substantially enhances the risk of pneumonia, though only for a short period.

February 4, 2016 |Report from the Regional SE Asia Meeting on Dengue Forecasting

On January 26, over 30 representatives from ten Southeast Asian countries convened in Kuala Lumpur, Malaysia, to review the status of disease forecasting based on climate and epidemiological data, in particular dengue, given the current strong El Niño season. During discussions, some countries reported high dengue transmission at the close of 2015 with the potential of a large 2016 outbreak while interventions will be implemented country-by-country. Every country is already doing some type of epidemic risk forecasting, ranging from qualitative to highly quantitative models. Regional initiatives are ongoing to improve the political and technical framework for data sharing and the University of Pittsburgh is planning to play a significant catalytic role in this process.

January 7, 2016 |Project Tycho® Study Leads to Regional Southeast Asia Meeting on Dengue Forecasting

In collaboration with the University of Malaya, the University of Pittsburgh will organize a Southeast Asia regional meeting in Kuala Lumpur, Malaysia on January 26, 2016. During this meeting, country partners and international experts will review the status of disease forecasting based on climate and epidemiological data, in particular for dengue fever, given the current strong El Niño season. This convening of partner institutions from Cambodia, Laos, Thailand, Vietnam, Singapore, Malaysia, Myanmar, Philippines, Taiwan, India and Indonesia, resulted in part from the study entitled “Region-wide synchrony and traveling waves of dengue across eight countries in Southeast Asia” published in the October 15, 2015 issue of the Proceedings of the National Academy of Sciences. All data for this study are publicly available from Project Tycho®.

In 2014, TLM launched the first computer coding curriculum in a United States prison (Code.7370). The students learn HTML, JavaScript, CSS, and Python. In addition to these front end skills, the curriculum has expanded to include web and logo design, data visualization and UX/UI.

October 30, 2015 |Pneumonia and the Role of Influenza

The influenza virus has long been commonly associated with pneumonia. Using data from Project Tycho®, the US Census Bureau and annual reports of the US Army Surgeon General, researchers have quantified the interaction, at a population scale, between pneumonia and influenza. They concluded that influenza infection substantially enhances the risk of pneumonia, though only for a short period. These findings were published in Nature Scientific Reports, October 21, 2015.




October 8, 2015 |Dengue Epidemics Linked to El Niño Season

Epidemics of dengue across Southeast Asia are linked to high temperatures brought by the El Niño weather phenomenon are the findings of an international research team led by the University of Pittsburgh Graduate School of Public Health. The findings, published in the Proceedings of the National Academy of Sciences (PNAS), are timely as the most intense El Niño in nearly two decades is emerging in the Pacific, raising the concern that a major increase in cases of dengue will occur throughout Southeast Asian countries early next year.

Dengue surveillance data are routinely collected by public health agencies around the world, but due to a variety of barriers, these data cannot always be used for scientific analysis. The University of Pittsburgh collaborated with colleagues at over 18 institutions across 8 countries in Southeast Asia to integrate dengue surveillance data into the Project Tycho® database and to detect patterns of disease transmission at a regional level.

"Large dengue epidemics occur unexpectedly, which can overburden the health care systems," said lead author William G. van Panhuis, MD, PhD, assistant professor of epidemiology at Pitt Public Health. "Our analysis shows that elevated temperatures can create the ideal circumstance for large-scale dengue epidemics to spread across a wide region. The ability to predict and prepare for these epidemics should lead to more effective disease surveillance and control efforts."

"This study will contribute toward a better understanding of the cyclical nature of dengue," said co-author Lam Sai Kit, PhD, professor at the University of Malaysia. These findings will help them to prepare for a worst-case scenario and immediate measures can be taken to counter its effect in the next few months.

February 12, 2015 |Project Tycho® Data Featured by The Wall Street Journal

Wall Street Journal

In an effort to bring more scientific evidence into the dialogue on vaccines, the Wall Street Journal used Project Tycho data to visualize the dramatic effect of vaccination programs in recent articles on measles in California and the impact of vaccination programs in the 20th century. These visualizations show the same dramatic pattern illustrated by the Project Tycho team in a 2013 NEJM publication that demonstrated that 100 million cases of childhood diseases have been prevented by vaccination programs in the US during the 20th century.

February 6, 2015 |Project Tycho® Provides Evidence for Measles Vaccination


As the measles outbreak is spreading in the US, currently affecting over 100 people in 14 states, the dialogue on vaccination has intensified. Health officials testified in a Congressional hearing on vaccine effectiveness and safety and the debate has spread widely among the public. The Project Tycho database provides scientific evidence on measles and 57 other infectious diseases across the U.S. since the late 1800s.

Project Tycho data has been used extensively for better insight in infectious disease patterns in the US and provides support to media and scientists to advance the use of public health data for decisions. The project has been featured recently in a variety of media including Bloomberg Business, the Pittsburgh Post-Gazette, the Pittsburgh Tribune Review, and KDKA and WPTS Pittsburgh Radio. Project Tycho previously demonstrated that 36 million cases of measles have been prevented since the vaccine was licensed in 1963 and over 100 million cases of 7 childhood diseases have been prevented in the US since 1924 (NEJM 2013). The Project Tycho team continues to investigate the resurgence of childhood diseases in the US and the role of vaccination.

April 23, 2014 |Project Tycho® Turns Big Data from Lazy to Active

The Department of Health and Human Services (HHS) has been collecting data for decades on the nation's health, demographics, social services, and scientific research. But what is the value of all this data if it isn't used?

As part of the President's government-wide Open Data Initiative to promote efficiency, effectiveness, and transparency, the HHS Health Data Initiative was launched three years ago. They have gathered vast troves of data which have been published at, and they recently reached a milestone of cataloging the one-thousandth data set. These data sets include data from the CDC, Centers for Medicare & Medicaid Services, the NIH, the Administration for Children and Families, and other agencies.

Project Tycho® is one example of how innovators have put accessible government data to use in their efforts to improve health care quality, guide individuals to available health care and social services, and inform health policy.

Earlier this year, Kathleen Sebelius, then HHS Secretary, made this statement in her remarks to the Aspen Institute's Care Innovation Summit on the topic of 'Reimagining health care delivery'. "We're seeing innovation in the academic and nonprofit sectors. A University of Pittsburgh initiative called Project Tycho, for example, unlocks CDC data on contagious diseases which goes back all the way to 1888. Among other things, they've identified more than 100 million cases of contagious illness that were prevented by immunizations."

March 6, 2014 |Project Tycho® Data Published in Nature

Project Tycho® data have been featured in a supplement on vaccination in the 6 March 2014 issue of the journal Nature. In a compelling infographic named “The Age of Vaccines”, the data show the dramatic decline of childhood diseases after licensure of vaccines. The infographic also highlights the importance of continued vaccination as for some diseases such as whooping cough, incidence rates are increasing and for other diseases such as measles, resurgences have been reported in previously protected populations. Project Tycho® data are freely available for anybody to use in innovative visualizations and data analyses.

January 20, 2014 |Project Tycho® Enhances Availability of US Disease Data

The U.S. Centers for Disease Control announced the enhanced availability of data for nationally notifiable diseases in the January 17 issue of the Morbidity and Mortality Weekly Report (MMWR). Provisional weekly data reported by U.S. states and territories and published weekly in the MMWR will become available and downloadable in machine-readable format starting in on January 10, 2014, through Currently, these data are available in downloadable text files from 1996 onwards from the CDC's WONDER system. Data from before 1996 are available in PDF format for MMWR volumes 1-30 (1952-1981) through CDC Stacks. The Project Tycho® database greatly advanced the availability of these historical data by providing open access to newly digitized weekly data from 1888 to the present. Project Tycho® enables the online exploration, visualization, and downloading of weekly nationally notifiable disease data and will continue to update its database every six months with newly available weekly data.

December 6, 2013 |Project Tycho® Release Featured in the New York Times

The release and publication of Project Tycho® data has been featured in an article of the New York Times online and print version of Thursday November 28th entitled “The Vaccination Effect: 100 Million Cases of Contagious Disease Prevented”. It emphasizes that the large amount of data digitized by the project provides an invaluable resource for science and policy and the importance of vaccination programs in the United States.

December 6, 2013 |Project Tycho® Data Available on

Through a collaboration with the Open Government Initiative, Project Tycho® data have been listed on as new open access resource for governmental data. In addition on the listing, has agreed to host Project Tycho® level 1 and level 2 data that can each be downloaded from this site as a one CSV file with a single click. Comments on this release have been made in the blog.

November 28, 2013 |Project Tycho® Data Version 1.0.0 Released for Public Access

After four years of data digitization and processing, the Project Tycho® Web site provites open access to newly digitized and integrated data from the entire 125 years history of United States weekly nationally notifiable disease surveillance data since 1888. These data can now be used by scientists, decision makers, investors, and the general public for any purpose. The Project Tycho® aim is to advance the availability and use of public health data for science and decision making in public health, leading to better programs and more efficient control of diseases. Read full press release.

Three levels of data have been made available: Level 1 data include data that have been standardized for specific analyses, Level 2 data include standardized data that can be used immediately for analysis, and Level 3 data are raw data that cannot be used for analysis without extensive data management.

November 28, 2013 |A Project Tycho® Study Estimates that 100 Million Cases of Contagious Diseases Have Been Prevented by Vaccination Programs in the United States Since 1924

In a paper published in the New England Journal of Medicine entitled “Contagious diseases in the United States from 1888 to the present,” a Project Tycho® study estimates that over 100 million cases have been prevented in the U.S. since 1924 by vaccination programs against polio, measles, mumps, rubella, hepatitis A, diphtheria, and pertussis (whooping cough). Vaccination programs against these diseases have been in place for decades but epidemics continue to occur. Despite the availability of a pertussis vaccine since the 1920s, the largest pertussis epidemic in the U.S. since 1959 occurred last year. This study was funded by the Bill & Melinda Gates Foundation and the National Institutes of Health and all data used for this study have been released through the online Project Tycho® data system as level 1 data.

“Historical records are a precious yet undervalued resource. As Danish philosopher Soren Kierkegaard said, we live forward but understand backward,” explained Dr. Burke, senior author on the paper. “By ‘rescuing’ these historical disease data and combining them into a single, open-access, computable system, we can now better understand the devastating impact of epidemic diseases, and the remarkable value of vaccines in preventing illness and death.” See an interview with the authors and an animation on the analysis.

November 28, 2013 |Project Tycho® Data Have Been Used by Undergraduate Students During the Undergraduate Data Palooza! 2013

The University of Pittsburgh MIDAS Center of Excellence funded by the National Institutes of Health conducted an international research competition for undergraduate students around the world named the Undergraduate Data Palooza! 2013. Hundreds of students registered as individuals or as teams for this competition which allowed them to use up to 10 Project Tycho® datasets for a creative analysis in one of three categories: 1) The historical context of a disease pattern, 2) a creative visualization, 3) a quantitative analysis of a disease pattern. The datasets included a wide variety of infectious diseases such as AIDS, Rocky Mountain spotted fever, tuberculosis, malaria, and others. Out of many outstanding submissions, one winning submission was selected in each category by an independent panel of reviewers. The winners of the competition were:

Runjing Lu and Lu Zhang, Emory University
Prasad Kanuparthi, University of Pittsburgh and Asish Balu, Pennsylvania State University
Emily Hu, Johns Hopkins University
