Infectious Disease Resources
Last Updated January 27, 2024
The Center for Outbreak Response Innovation is monitoring key disease for the United States. The morbidity for each disease, along with key resources for the public, state and local health departments, and governors are available below. The dates for the most recent resources are shown in the brackets for the disease column.
Weekly Morbidity Table - Week 3 2025
Disease (Click for resources) | Current Week
| Cum YTD 2025 | Cum YTD 2024 |
| Avian Influenza A(H5) [1.24.25] | 0 | 67 | 0 |
| Dengue [1.9.25] | 1 | 30 | 170 |
| Eastern Equine Encephalitis (EEE) [9.10.24] | - | - | - |
| Rubella | - | - | 1 |
| Measles*[12.6.24] | 1 | 1 | 7 |
| Mumps | 1 | 7 | 25 |
| Mpox [1.8.25] | - | 20 | 152 |
| Oropouche**[11.19.254] | - | - | 0 |
| Pertussis [9.10.24] | 235 | 953 | 587 |
*Measles data is published by CDC on the NNDSS Wonder Tables and the Measles Cases and Outbreak page weekly. Due to reporting schedules these two sources may have somewhat different reports for 2025 cases. CORI will rely on the most recent data when differences are observed.
** Oropouche is not currently a nationally notifiable disease. As a result, CORI will rely on other CDC surveillance updates as part of ArboNET.
- Data is not available
Special publication note: Current data is provided by the Centers for Disease Control and Prevention (CDC). In the event CDC data is delayed, CORI will be relying on state and local data for the interim.
Vector-Borne Disease Resources
Vector-Borne diseases encompass a wide range of illnesses transmitted by arthropods, including mosquitoes, ticks, and midges, many with potential for severe disease.
*The CORI research team is actively updating this page to include diseases transmitted by a variety of vectors, including mosquitoes, ticks, and midges. Please check back regularly as these updates are posted.

Mpox
The mpox virus is classified into 2 main clades, clade I and clade II, with each further subdivided into clade Ia, the newly identified clade Ib, clade IIa, and clade IIb, the clade which was responsible for the 2022 global outbreak. Since the 2022 clade IIb mpox outbreak began, there have more than 106,310 cases and more than 234 deaths reported in 123 countries, though world-wide reported data likely do not include the most recent outbreaks of clade I in the Africa region. According to the US Centers for Disease Control and Prevention (US CDC) and the World Health Organization (WHO), the US has reported 33,812 mpox cases as of August, 2024. The US outbreak has continued to grow at a low but steady pace in 2024, with 2,179 cases recorded year to date as of October 4, 2024. With the continued transmission of clade IIb in the US and globally and the increased transmission of clade I and II in the Africa region, experts are concerned that changes in the national and global landscape have the potential to increase health risks for specific US populations.
Avian influenza A(H5)
The CORI research team is monitoring and evaluating the human health risks associated with H5 in the United States
Measles
CORI is actively engaged with state and local health departments responding to and preparing for measles outbreaks. We develop tailored tools aimed at optimizing every stage of the outbreak response process.
The following resources are intended for health departments, clinicians, and the general public.
Pertussis (Whooping Cough)
Pertussis, also known as whooping cough, remains a significant public health concern in the United States despite widespread vaccination. The cyclical nature of pertussis outbreaks, waning immunity in adolescents and adults, and vaccine hesitancy contribute to periodic resurgences of the disease. Continued efforts in maintaining high vaccination rates, especially among pregnant women and infants, along with improved diagnostic methods and public awareness campaigns, are crucial for controlling pertussis and protecting vulnerable populations.
Disease Outbreak Reporting Project
Disease Reporting and Forecasts
CORI is driving public health advancements by collaborating with key partners to improve the way infectious disease reports are communicated. Through strategic partnerships with TV meteorologists and a large healthcare organization, CORI ensures that critical health information reaches both local communities and large workforce populations, empowering timely decision-making and proactive responses to public health threats. These efforts are led by Dr. Eric Toner, Senior Scholar at the Johns Hopkins Center for Health Security.
These initiatives aim to enhance public awareness and preparedness by delivering tailored health insights directly to communities through trusted channels, such as local news and large employers.
Infectious Disease Modeling & and Public Health Analytics Trainings
CORI has curated a collection of training resources that may be of interest to public health practitioners, epidemiologists, data analysts, informatics professionals, and decision-makers involved in disease surveillance, outbreak management, and public health analytics.
