Communicable diseases in humanitarian operations and disasters

Military organisations have battled communicable disease for millennia. They have pioneered disease prevention from the Crusades to the World Wars and continue to do so today. Predeployment vaccinations and chemoprophylaxis are effective in preventing communicable disease, as is reliable vector destruction and bite prevention, especially in the era of multidrug resistant organisms. These measures are unlikely to be fully possible in disasters, but reactive vaccination and efforts to reduce exposure to communicable disease should be a priority. Communicable diseases can be challenging to diagnose-the UK Defence Medical Services have become familiar with tools such as multiplex PCR and mass spectrometry. These have the potential to accurately identify organisms and sensitivity patterns in austere environments. Management of communicable diseases depends on accurate diagnosis and has a largely well-established evidence base but can be limited by a lack of resources and skills in an austere setting, therefore telemedicine can assist diagnosis and treatment of infections by projecting specialist skill. Systems such as EpiNATO2 are useful in monitoring diseases and identifying trends in order to establish control measures. Many of these tools and techniques are effective in austere environments and offer learning opportunities for those providing care in similar settings. Further research is ongoing into diagnostic tools as well as remote management.
