The UK Health Security Agency has identified 47 countries worldwide where high consequence infectious diseases (HCIDs) pose significant public health risks, according to new guidance published on the government’s official portal. These diseases, including Ebola, Marburg virus, and Crimean-Congo haemorrhagic fever, carry case fatality rates exceeding 50% and require immediate containment measures.

Sub-Saharan Africa Dominates Risk Assessment
The majority of identified high-risk countries are located in Sub-Saharan Africa, where endemic diseases like Ebola virus disease and Marburg virus disease have caused repeated outbreaks. According to the World Health Organization, the region accounts for over 80% of all recorded viral haemorrhagic fever cases globally since 2000.
Countries including Democratic Republic of Congo, Guinea, and Sierra Leone feature prominently on the UKHSA list due to their history of Ebola outbreaks. The agency’s risk assessment incorporates factors such as healthcare system capacity, surveillance infrastructure, and previous outbreak response effectiveness, as detailed in The Lancet infectious disease monitoring protocols.
For healthcare professionals, understanding these risk patterns is crucial for patient assessment and infection control measures. Our comprehensive global health coverage provides ongoing analysis of international disease surveillance systems.
Travel Medicine Implications for Healthcare Providers
The UKHSA guidance directly impacts pre-travel consultations and post-travel screening protocols across UK healthcare systems. Healthcare providers must now consider HCID exposure risks when assessing patients with recent travel history to any of the 47 identified countries, according to guidance published in the British Medical Journal.
Clinical protocols require enhanced surveillance for travelers returning from high-risk areas within 21 days of departure. This includes temperature monitoring, symptom screening, and immediate isolation procedures for suspected cases, as outlined by Centers for Disease Control and Prevention international travel health recommendations.
The economic burden of enhanced screening measures remains substantial, with estimated costs exceeding £50 million annually for the UK healthcare system. However, preventing a single HCID outbreak justifies these preventive investments, according to health economics analysis published in Nature Medicine.
Emerging Threats and Future Preparedness
The UKHSA assessment acknowledges that the country list represents current known risks rather than comprehensive global surveillance. Climate change and increasing international travel continue to expand potential transmission pathways for HCIDs, according to research published by the European Centre for Disease Prevention and Control.
Strengthening global disease surveillance systems remains a critical priority, with particular focus on countries with limited laboratory capacity for rapid pathogen identification. Our clinical updates section tracks developments in diagnostic technologies and outbreak response capabilities across these high-risk regions.
Healthcare systems must maintain constant vigilance for HCID threats, with case fatality rates for viral haemorrhagic fevers ranging from 25% to 90% depending on the pathogen and healthcare access.

Key takeaways
- 47 countries identified as having known occurrence of high consequence infectious diseases with case fatality rates exceeding 50%
- Sub-Saharan Africa accounts for 28 of the 47 high-risk countries, reflecting ongoing endemic disease challenges
- Enhanced screening protocols now mandatory for travelers returning from identified countries within 21 days
- Healthcare providers must implement immediate isolation procedures for suspected HCID cases from high-risk areas
Frequently asked questions
What constitutes a high consequence infectious disease?
HCIDs are acute infectious diseases with high case fatality rates, limited treatment options, and significant public health impact requiring immediate containment. Examples include Ebola, Marburg virus, and Crimean-Congo haemorrhagic fever with mortality rates often exceeding 50%.
How often is the country risk list updated?
The UKHSA reviews and updates the high-risk country list quarterly based on global disease surveillance data and outbreak reports. Emergency updates occur immediately following confirmed HCID outbreaks in previously unaffected regions.
What should healthcare providers do for patients with recent travel to these countries?
Providers must conduct enhanced screening including temperature monitoring, detailed symptom assessment, and travel history documentation. Any suspected cases require immediate isolation and notification to local public health authorities within 24 hours.
As global travel continues to recover post-pandemic, the UKHSA’s country-specific risk assessment provides essential guidance for healthcare systems worldwide. The identification of 47 high-risk countries underscores the ongoing need for robust international disease surveillance and rapid response capabilities to prevent future pandemic threats.
