Global Outbreak Studies

Understanding, Tracking, and Responding to Infectious Disease Outbreaks Worldwide

Global Outbreak Studies is a dedicated scientific segment of the Universal Conference on Infectious Diseases (UCID) focused on the investigation, surveillance, prevention, control, and management of infectious disease outbreaks across regions and populations.

This segment brings together epidemiologists, infectious disease physicians, microbiologists, virologists, public health professionals, researchers, healthcare leaders, policymakers, laboratory scientists, infection-control specialists, and other experts to examine how infectious diseases emerge, spread, evolve, and impact communities.

The program provides a multidisciplinary platform for presenting outbreak investigations, epidemiological studies, surveillance data, emerging pathogen research, outbreak response strategies, public health interventions, genomic surveillance, diagnostic innovations, vaccination programs, antimicrobial resistance, One Health approaches, and lessons learned from recent epidemics and pandemics.

About Global Outbreak Studies

Infectious disease outbreaks can develop rapidly and cross geographical, demographic, and national boundaries. Effective outbreak management therefore requires timely detection, reliable laboratory confirmation, transparent communication, coordinated surveillance, evidence-based interventions, and international collaboration.

The Global Outbreak Studies segment explores outbreaks from the initial detection of unusual disease activity through investigation, risk assessment, response, containment, recovery, and post-outbreak evaluation.

The segment encourages researchers and public health professionals to move beyond describing case numbers and examine the broader questions surrounding outbreaks:

What triggered or enabled the outbreak?
How was the outbreak detected?
What surveillance systems identified transmission?
Which populations were most affected?
What epidemiological patterns emerged?
How rapidly did transmission occur?
What diagnostic approaches were used?
What interventions reduced transmission?
What barriers affected outbreak control?
How did healthcare systems respond?
What role did vaccination and therapeutics play?
How did misinformation or risk communication affect the response?
What lessons can strengthen future pandemic preparedness?

Key Areas of Focus

1. Emerging and Re-Emerging Infectious Diseases

Research is encouraged on diseases that are newly recognized, expanding geographically, or returning after periods of reduced transmission.

Topics may include:

Emerging viral diseases
Re-emerging bacterial infections
Novel respiratory pathogens
Vector-borne diseases
Zoonotic infections
Food- and waterborne diseases
Hemorrhagic fever outbreaks
Emerging fungal infections
Neglected tropical diseases
Vaccine-preventable disease outbreaks
Antimicrobial-resistant infections

2. Outbreak Epidemiology and Investigation

This area focuses on the scientific investigation of infectious disease outbreaks and the identification of transmission patterns.

Potential topics include:

Outbreak detection and verification
Case definition development
Descriptive epidemiology
Person–place–time analysis
Attack rates and incidence
Case-fatality analysis
Transmission dynamics
Reproductive-number estimation
Exposure investigations
Contact tracing
Cluster investigations
Risk-factor analysis
Epidemic curves
Spatial epidemiology
Mathematical and statistical outbreak modelling
Forecasting and scenario analysis

Researchers should clearly describe the population, geographic setting, study period, data sources, analytical methods, limitations, and uncertainty associated with their findings.

3. Global Disease Surveillance

Effective surveillance is fundamental to early outbreak detection and rapid response.

Presentations may address:

Indicator-based surveillance
Event-based surveillance
Syndromic surveillance
Laboratory-based surveillance
Genomic surveillance
Wastewater surveillance
Digital disease surveillance
Sentinel surveillance
Community-based surveillance
Cross-border surveillance
Real-time outbreak dashboards
Early warning systems
Artificial intelligence for outbreak detection
Data integration and interoperability

The International Health Regulations (IHR) provide an international legal framework for countries to manage public-health risks with potential cross-border implications and establish obligations relating to surveillance, response capacity, and notification of relevant public-health events. The current IHR text incorporates amendments adopted in 2014, 2022, and 2024. (World Health Organization)

Recent Global Outbreak Case Studies

Case Study 1: Bundibugyo Virus Disease – Democratic Republic of the Congo

The 2026 Bundibugyo virus disease outbreak in the Democratic Republic of the Congo illustrates the complexity of responding to a rapidly expanding outbreak in a setting affected by insecurity, population displacement, limited healthcare access, and challenging surveillance conditions.

According to WHO's 21 September 2026 situation information, the Democratic Republic of the Congo had reported 7,773 confirmed cases and 3,759 confirmed deaths, while confirmed and probable cases had also been reported in Uganda and a case had been treated in France. WHO reported a confirmed-case fatality ratio of approximately 48% in the DRC data available at that time. (World Health Organization)

The outbreak expanded across multiple health zones and provinces, creating substantial demands for:

Active case finding
Laboratory testing
Contact monitoring
Infection prevention and control
Clinical management
Community engagement
Cross-border coordination
Healthcare-worker protection
Vaccination research and evaluation

WHO reported that the outbreak occurred in a complex humanitarian environment involving insecurity, displacement, food insecurity, and constrained access to healthcare. (World Health Organization)

Research questions arising from this outbreak

Researchers may examine:

How can outbreak surveillance function effectively in conflict-affected settings?
How does population displacement influence transmission?
What strategies improve healthcare-worker protection?
How can laboratory capacity be expanded during rapidly evolving outbreaks?
How should candidate vaccines be evaluated when evidence for protection against a particular viral species remains limited?
How can cross-border surveillance be strengthened?

This case demonstrates why outbreak preparedness must incorporate not only biomedical interventions but also health-system capacity, logistics, security, community engagement, and regional coordination.

Case Study 2: Global Mpox Outbreak

Mpox provides an important example of how an infectious disease can evolve from localized transmission into a prolonged multinational outbreak involving different viral clades and transmission patterns.

WHO reports that the global mpox outbreak began in 2022 and continues to require coordinated international surveillance and response. Clade Ib has expanded geographically, while Clade IIb continues to circulate across multiple WHO regions. (World Health Organization)

WHO's September 2026 situation reporting notes that, from January 2022 through May 2026, 187,117 confirmed cases and 510 deaths were reported by 144 countries. The data also demonstrate substantial variation in reported transmission across WHO regions and over time. (World Health Organization)

Key research themes

Molecular epidemiology of mpox
Viral clade evolution
Transmission dynamics
Vaccine effectiveness
Diagnostic accessibility
Community-based surveillance
Healthcare-associated transmission
Cross-border disease surveillance
Risk communication
Stigma-sensitive public-health interventions
Equity in access to vaccines and therapeutics

The mpox experience highlights the importance of combining laboratory, genomic, epidemiological, clinical, and community-level evidence.

Case Study 3: Global Cholera and Acute Watery Diarrhoea

Cholera continues to demonstrate how infectious disease outbreaks can be amplified by environmental and social conditions.

WHO reported that during June 2026, 47,758 cholera and acute watery diarrhoea cases were reported from 18 countries across four WHO regions. The increase was particularly associated with transmission in settings affected by conflict, population displacement, inadequate water, sanitation and hygiene services, and rainfall. (World Health Organization)

From 1 January through 28 June 2026, WHO reported 163,031 cholera and acute watery diarrhoea cases and 1,686 deaths from 26 countries across four WHO regions. (World Health Organization)

Research priorities

Water, sanitation and hygiene interventions
Oral cholera vaccination
Climate-sensitive disease surveillance
Flood-associated outbreaks
Outbreak response in humanitarian settings
Rapid diagnostic testing
Community-level prevention
Antimicrobial stewardship
Cross-border outbreak management
Health-system preparedness

Cholera demonstrates that outbreak prevention cannot depend exclusively on clinical treatment. Sustainable control requires investment in safe water, sanitation, hygiene, vaccination, surveillance, community engagement, and resilient health infrastructure.

Case Study 4: Influenza at the Human–Animal Interface

Avian influenza illustrates the importance of the One Health approach because potentially zoonotic influenza viruses circulate in animal populations and can occasionally infect humans.

WHO's September 2026 influenza update reported new human detections involving A(H5N1), A(H9N2), and variant A(H1N2)v viruses during the reporting period. WHO also noted continued circulation of influenza viruses with zoonotic potential among animal populations. At that point, there was no reported sustained human-to-human transmission associated with those newly reported infection events. (World Health Organization)

Research opportunities

Animal-to-human transmission
Wildlife surveillance
Poultry surveillance
Genomic characterization
Molecular evolution
Occupational exposure
Pandemic influenza preparedness
Vaccine development
Antiviral preparedness
One Health surveillance
Human–animal–environment interfaces

The case demonstrates why human health surveillance should be integrated with veterinary, wildlife, environmental, agricultural, and laboratory surveillance systems.

One Health and Global Outbreak Preparedness

Modern infectious disease threats increasingly require collaboration between human health, animal health, and environmental disciplines.

The One Health approach recognizes that human, animal, plant, and environmental health are interconnected.

Global outbreak studies may therefore incorporate:

Human Health → Animal Health → Environmental Health → Genomic Surveillance → Public Health Response

Important research areas include:

Zoonotic spillover
Wildlife disease surveillance
Livestock-associated infections
Vector ecology
Environmental reservoirs
Climate-sensitive infectious diseases
Antimicrobial resistance
Food safety
Ecosystem disruption
Land-use change
Human–animal interactions

Genomic Surveillance and Molecular Epidemiology

Genomic epidemiology has become an increasingly important component of outbreak investigation.

Researchers can use pathogen genomic data to investigate:

Transmission clusters
Viral or bacterial evolution
Introduction events
Geographic spread
Genetic diversity
Antimicrobial-resistance markers
Vaccine-related evolutionary pressures
Emerging variants
Transmission chains

However, genomic findings should be interpreted alongside epidemiological and clinical evidence rather than treated as independent proof of transmission pathways.

Presenters should clearly describe:

Sequencing methodology
Sample selection
Coverage and quality metrics
Reference genomes or databases
Bioinformatic pipelines
Phylogenetic methods
Sampling limitations
Missing data
Uncertainty
Data-sharing practices

Artificial Intelligence and Digital Technologies in Outbreak Response

Artificial intelligence, machine learning, digital epidemiology, geographic information systems, and automated surveillance systems are increasingly being investigated for outbreak preparedness and response.

Potential applications include:

Early outbreak signal detection
Epidemic forecasting
Risk mapping
Image-based diagnosis
Genomic analysis
Contact-tracing support
Resource allocation
Healthcare demand forecasting
Natural-language processing of outbreak reports
Automated literature surveillance
Wastewater surveillance analytics
Decision-support systems

AI-generated or AI-assisted findings should be independently validated before being presented as established scientific evidence.

Researchers should disclose the use of AI tools where relevant, describe their role in the research workflow, and maintain human responsibility for scientific interpretation, data integrity, and conclusions.

Antimicrobial Resistance and Outbreaks

Antimicrobial resistance (AMR) can complicate outbreak detection, treatment, infection prevention, and healthcare-system response.

Global Outbreak Studies therefore welcomes research addressing:

Multidrug-resistant bacterial outbreaks
Hospital-acquired infections
Community transmission of resistant organisms
Antimicrobial stewardship
AMR surveillance
Rapid susceptibility testing
Genomic AMR surveillance
Infection prevention and control
Antibiotic use during outbreaks
One Health AMR
Novel antimicrobial strategies

Presentations should distinguish antimicrobial resistance mechanisms from clinical treatment recommendations and should avoid unsupported claims regarding drug efficacy.

Climate Change, Environment, and Infectious Disease Outbreaks

Environmental change can influence infectious disease transmission through multiple pathways.

Research may examine relationships between infectious diseases and:

Temperature changes
Rainfall
Flooding
Drought
Extreme weather
Vector distribution
Water availability
Food systems
Population displacement
Urbanization
Ecosystem changes

The goal is not simply to associate climate variables with disease occurrence but to investigate the mechanisms, population vulnerabilities, geographical differences, and appropriate adaptation measures.

The conference encourages evidence-based evaluation of outbreak interventions, including:

Detection

Early-warning systems
Case finding
Laboratory confirmation
Surveillance networks

Investigation

Contact tracing
Exposure assessment
Epidemiological analysis
Genomic investigation

Containment

Isolation where appropriate
Infection prevention and control
Vaccination
Treatment
Environmental controls

Communication

Risk communication
Community engagement
Misinformation management
Transparent scientific communication

Recovery

Health-system restoration
Long-term surveillance
Mental and social support
Post-outbreak evaluation
Preparedness improvements

Ethical and Scientific Standards for Outbreak Presentations

All submissions to the Global Outbreak Studies segment should meet applicable scientific, ethical, legal, and institutional requirements.

1. Human Participant Protection

Research involving human participants should receive appropriate review from an independent ethics committee, institutional review board, or other competent review body, as required by applicable national and institutional regulations. WHO emphasizes protection of participants' dignity, rights, and welfare and highlights the principles of autonomy, beneficence, and justice. (World Health Organization)

Authors should provide relevant ethics approval information where applicable.

2. Informed Consent

Where informed consent is required, researchers should obtain consent using procedures appropriate to the study and jurisdiction.

For presentations containing potentially identifiable patient information, authors should take particular care to protect privacy. ICMJE guidance states that identifying information should not be published unless scientifically essential and appropriate written consent for publication has been obtained. (ICMJE)

3. Privacy and Confidentiality

Presenters should:

Remove names and personal identifiers.
Avoid unnecessary demographic details that could enable re-identification.
De-identify clinical images.
Avoid displaying hospital numbers or other unique identifiers.
Obtain appropriate consent for identifiable photographs.
Follow applicable privacy and data-protection laws.

De-identification should not distort scientifically relevant information.

4. Ethical Approval and Outbreak Investigations

Not every public-health activity is automatically classified as research. Authors should determine whether their activity constitutes research, surveillance, program evaluation, or another category under the relevant national and institutional framework.

Where a project is classified as research involving human participants, appropriate ethics review should be documented.

5. Data Integrity and Transparency

Presenters should accurately report:

Data sources
Study population
Inclusion and exclusion criteria
Dates of data collection
Statistical methods
Missing data
Limitations
Uncertainty

Images should respect the dignity of affected individuals and communities. ICMJE guidance specifically emphasizes avoiding images that unnecessarily portray people in distress or vulnerable situations or reinforce stereotypes. (ICMJE)

9. Biosafety and Dual-Use Considerations

Outbreak research involving pathogens, laboratory procedures, genetic information, or experimental interventions should be presented responsibly.

Presentations should prioritize scientific understanding and public-health benefit while avoiding unnecessary operational detail that could create biosafety, biosecurity, or dual-use concerns.

Researchers should comply with applicable:

Institutional biosafety requirements
National regulations
Laboratory containment requirements
Material-transfer requirements
Pathogen and genetic-resource regulations
Data-sharing restrictions
Biosecurity policies

Global Collaboration for Future Outbreaks

Infectious disease outbreaks rarely remain confined to a single discipline. Effective preparedness requires collaboration among researchers, clinicians, laboratories, public-health agencies, governments, communities, animal-health professionals, environmental scientists, technology specialists, and international organizations.

The amended International Health Regulations reinforce the importance of international cooperation in managing public-health risks that can cross national borders. The amendments that entered into force in September 2025 also introduced a new global alert level, the pandemic emergency, and strengthened provisions relating to coordination, equity, and access to health products and financing.

The Global Outbreak Studies segment of UCID aims to provide a scientific forum where evidence from diverse regions can be shared, critically evaluated, and translated into practical approaches for infectious disease preparedness.

Submission Invitation

Researchers, clinicians, epidemiologists, public-health professionals, laboratory scientists, and multidisciplinary experts are invited to present original research, outbreak investigations, surveillance studies, systematic reviews, case studies, field experiences, technological innovations, and evidence-based public-health strategies relevant to global infectious disease outbreaks.
