It is a question that does not cross most travellers’ minds when planning a trip, yet respiratory infections including pneumonia are among the more common health issues people encounter abroad. Changes in climate, long-haul flights, crowded environments and exposure to unfamiliar pathogens can all increase your vulnerability. At Akasi Pharmacy, our travel clinic team helps you identify the risks that matter for your specific trip and make sure you are protected before you leave. Get in touch with us today to arrange your consultation.
What Is Pneumonia and How Do You Catch It
Pneumonia is an infection that causes inflammation in one or both lungs. It can be caused by bacteria, viruses or, less commonly, fungi. The most frequent bacterial cause is Streptococcus pneumoniae, often referred to as pneumococcal disease. Common viral causes include influenza and, more recently, COVID-19.
It spreads primarily through respiratory droplets when an infected person coughs, sneezes or talks nearby. This makes crowded spaces such as airports, aircraft cabins, cruise ships, hostels and busy tourist attractions environments where transmission risk is naturally higher.
Why Travel Increases Your Risk
Several factors that are common during travel can lower your body’s defences or increase your exposure to respiratory infections.
⇾ Aircraft cabins recirculate air for long periods, bringing passengers into close contact with others who may be unwell
⇾ Disrupted sleep, dehydration and the physical demands of long journeys can suppress immune function temporarily
⇾ Exposure to different strains of bacteria and viruses that your immune system has not previously encountered
⇾ Travelling during winter seasons in different hemispheres, where respiratory illness is more prevalent
⇾ Staying in shared accommodation or attending large gatherings and events
⇾ Extremes of temperature, particularly moving between hot outdoor environments and heavily air-conditioned spaces
None of these factors make pneumonia inevitable, but they do mean that travel is not a risk-free environment for respiratory health, particularly for older travellers, young children or those with underlying health conditions.

Destinations and Settings That Carry Higher Risk
Pneumonia risk during travel is not confined to any one region. However, certain types of travel and certain environments are associated with greater exposure:
| Travel Setting | Why Risk May Be Elevated |
|---|---|
| Long-haul flights | Enclosed space, low humidity, proximity to other passengers |
| Cruise ships | Large numbers of people in shared spaces, documented history of respiratory outbreaks |
| Pilgrimages and mass gatherings | Extremely high density of people from varied backgrounds |
| High altitude destinations | Reduced oxygen levels can strain the respiratory system |
| Areas with high air pollution | Irritated airways are more susceptible to infection |
| Healthcare settings abroad | Exposure to antibiotic-resistant strains in some regions |
Pneumococcal and Flu Vaccination Before Travel
Vaccination is the most effective tool for reducing your risk of pneumonia and related complications. Two vaccines are particularly relevant for travellers:
Pneumococcal vaccine protects against Streptococcus pneumoniae, the leading bacterial cause of pneumonia. It is routinely offered to adults aged 65 and over and those with certain underlying health conditions on the NHS, but younger adults who are travelling frequently or to higher risk settings may also benefit.
Influenza vaccine is important for travellers because flu is a common trigger for secondary bacterial pneumonia. Flu circulates year-round in tropical regions and during different seasons in the southern hemisphere, meaning your travel timing may expose you to strains not covered by the current UK seasonal vaccine.
Vaccination against pneumococcal disease and flu are among the key preventive steps recommended, alongside good hygiene and avoiding smoking.
Who Should Pay Particular Attention
While anyone can develop pneumonia, some groups face a greater risk of serious illness:
⇾ Adults aged 65 and over
⇾ Those with chronic lung conditions such as asthma or COPD
⇾ People with heart disease, diabetes or a weakened immune system
⇾ Smokers, whose airways are more vulnerable to infection
⇾ Very young children, particularly in settings with poor air quality
If you fall into any of these groups, a pre-travel health review is especially worthwhile.

Practical Steps to Reduce Your Risk While Travelling
Alongside vaccination, a few straightforward habits can meaningfully reduce your exposure:
⇾ Wash your hands regularly, particularly before eating and after using public transport
⇾ Stay well hydrated throughout long flights and journeys
⇾ Avoid close contact with people who are visibly unwell where possible
⇾ Get adequate rest before and during travel to support your immune system
⇾ Avoid smoking and limit alcohol consumption, both of which can reduce your body’s ability to fight infection
⇾ Consider a face covering in extremely crowded or enclosed spaces, particularly if you are in a higher risk group
FAQs
Is pneumonia common in travellers?
Pneumonia itself is not the most commonly reported travel illness, but respiratory infections broadly are among the more frequent health complaints during and after travel. Pneumonia represents the more serious end of that spectrum and is worth taking preventive steps against, particularly for those in higher risk groups.
Can I get vaccinated against pneumonia at a private travel clinic?
Yes. If you do not qualify for NHS pneumococcal vaccination or would like to review your vaccination status ahead of travel, our team can assess your needs and administer the vaccine privately as part of a broader travel health consultation.
How is pneumonia treated if I become unwell abroad?
Bacterial pneumonia is typically treated with antibiotics, and most cases respond well when treatment begins promptly. If you develop symptoms such as a persistent high fever, chest pain, difficulty breathing or a worsening cough while abroad, seek local medical attention without delay rather than waiting until you return home.
Does the flu vaccine protect against pneumonia?
The flu vaccine does not directly prevent pneumonia, but it reduces the risk of influenza, which is one of the most common triggers for secondary bacterial pneumonia. Combined with the pneumococcal vaccine, it provides meaningful protection against two of the most significant risk factors.
Should I carry any medication for respiratory illness when travelling?
This depends on your individual health history and destination. Some travellers with pre-existing respiratory conditions are advised to carry a course of standby antibiotics or an action plan from their GP. This is something to discuss during your pre-travel consultation rather than something to self-prescribe.
Does air conditioning on planes or in hotels cause pneumonia?
Air conditioning itself does not cause pneumonia, but heavily air-conditioned environments can dry out the mucous membranes in your nose and throat, slightly reducing their ability to trap pathogens. Staying hydrated helps counteract this. Legionnaire’s disease, a serious form of pneumonia, can be associated with poorly maintained water systems including certain air conditioning units, though this is uncommon in well-regulated hotels.
Protecting Your Health Before You Travel
Pneumonia may not be the first risk that comes to mind when planning a trip, but for many travellers it represents a genuinely avoidable health threat. A short pre-travel consultation gives you the opportunity to review your vaccination status, understand the specific risks of your destination and travel in a way that protects your respiratory health.
