In an era of unprecedented global connectivity, air transport serves as a vital engine for economic growth while simultaneously posing potential risks for the spread of infectious diseases. Airlines face the critical challenge of safeguarding passenger and crew health while maintaining operational continuity. This comprehensive guide outlines current disease threats, preventive measures, and emergency protocols to enhance the aviation industry's preparedness for public health emergencies.
Mpox Outbreak: Current Status and Management Strategies
On August 14, 2023, the World Health Organization (WHO) declared the mpox outbreak in the Democratic Republic of Congo (DRC) and other African nations a Public Health Emergency of International Concern (PHEIC). This marks the second such designation for mpox, following the initial PHEIC declaration in July 2022 when the disease spread rapidly to countries with no prior reported cases.
Despite this classification, WHO explicitly advises against implementing international travel or trade restrictions. Key facts about mpox include:
Disease Characteristics
- Not a new disease: Mpox remains endemic in Central Africa, particularly near tropical rainforests. While smallpox was eradicated in 1980, mpox persists in Central and West African nations. Since May 2022, countries outside Africa with no prior transmission history have reported cases.
Transmission Pathways
- Direct contact with infected animals (primates, squirrels, rodents)
- Close physical contact with infected individuals, particularly through characteristic skin lesions
- Contact with contaminated materials
The virus primarily enters through broken skin, mucous membranes (oral, ocular, genital, anal-rectal), or respiratory routes.
Symptom Identification
Many patients initially develop distinctive fluid-filled vesicles that progress to scabs. Infectiousness persists until complete skin healing occurs. Preceding or accompanying symptoms may include fever, malaise, and pain. The incubation period ranges from 5-21 days post-exposure.
Preventive Measures
- Avoid contact with animals in endemic regions
- Limit close contact with symptomatic individuals, particularly those displaying rashes
- Maintain rigorous hand hygiene using soap/water or alcohol-based solutions
- Follow local vaccination guidelines for at-risk populations
Travel Recommendations
WHO maintains its position against travel restrictions, advising symptomatic individuals (particularly those with fever and rash) to postpone travel. Standard infectious disease protocols apply for in-flight management, with ongoing global surveillance.
Additional Disease Threats for Aviation
COVID-19
In May 2023, WHO transitioned COVID-19 from PHEIC status to long-term management, reflecting the pandemic's evolution into an ongoing health challenge.
Viral Hemorrhagic Fevers
Recent outbreaks include Uganda's 2022 Ebola epidemic and concurrent Marburg virus outbreaks in Equatorial Guinea and Tanzania in early 2023. Nigeria continues to battle Lassa fever since 2024. While transmission risk during air travel remains low (requiring close contact), these diseases warrant monitoring.
Airline Emergency Preparedness Protocols
Drawing from past outbreak experiences, airlines should implement comprehensive response plans including:
- Emergency response checklists for public health crises
-
Staff-specific guidelines covering:
- Universal precaution kits
- Crew health measures during pandemics
- Maintenance personnel protocols
- Baggage handler safety procedures
- Passenger agent interactions
-
Operational documents including:
- Passenger locator forms
- Respiratory infection prevention measures
- Standardized cabin announcements
- Cabin air quality briefings
- Cleaning staff protocols
