The COVID-19 pandemic has had a significant impact on the aviation industry, with travel bans and border closures disrupting operations worldwide. As some flights and airports remain open, ensuring the health and safety of passengers and staff is crucial. Airports, being large facilities that attract crowds from all over the world, pose unique challenges in preventing the spread of the coronavirus. While screening travellers may not be fully effective, it can help break transmission chains and reduce the probability of superspreading events. Airports can implement measures such as simplifying boarding procedures, non-contact boarding, and setting up special passages to prevent cross-infection. Additionally, clear communication with passengers and staff about the importance of individual behaviours, such as wearing masks and maintaining hygiene, is vital. The effective utilisation of new technologies and tools can also enhance prevention efforts.

What You'll Learn
Screening travellers
However, research has shown that screening travellers may not be very effective in preventing the spread of COVID-19. One study estimated that 46% of infected travellers would not be detected, depending on the incubation period, sensitivity of exit and entry screening, and the proportion of asymptomatic cases. Another study found that screening travellers will miss more than half of people exposed to the virus. This is partly because, during flu season, many people who do not have COVID-19 may be detained as false positives due to the similarity of symptoms.
Despite the limitations of screening travellers, it may still have some indirect benefits in preventing the spread of COVID-19. For example, it can help to break new chains of transmission and reduce the probability of super-spreading events, making it less likely that the number of infected people will multiply.
In addition to traveller screening, other measures can be taken to prevent the spread of COVID-19 at airports. These include clear communication to passengers and staff about the seriousness of the virus and the importance of individual behaviours such as handwashing and social distancing. Airports and airlines may also implement aggressive measures, such as chemical bombing solutions, to kill any germs in the environment before passengers board their flights. Additionally, disinfecting and sanitising surfaces can help to curb the transmission of the virus.

Vaccination and good hygiene
Firstly, it is important to stay up to date with COVID-19 vaccines. While vaccinated people can still get infected, staying current with vaccines significantly lowers the risk of severe illness, hospitalization, or death. Vaccination is a core prevention strategy that protects individuals and communities.
In addition to vaccination, practicing good hygiene is essential. This includes basic preventative measures such as frequent and thorough handwashing, especially after touching surfaces in crowded spaces like airports. Hand sanitiser can be used when handwashing facilities are not available. Additionally, avoid touching your face, especially your eyes, nose, and mouth, as these are entry points for the virus.
Good respiratory hygiene is also crucial. Cover your mouth and nose with a tissue when coughing or sneezing, then dispose of the tissue immediately and wash your hands. If no tissue is available, cough or sneeze into your elbow or sleeve, not your hands. These practices can help prevent the spread of droplets containing the virus.
Furthermore, maintaining a safe distance from others, where possible, is important. Social distancing can reduce the chances of coming into close contact with respiratory droplets from infected individuals. In crowded spaces like airports, try to maintain a buffer zone around yourself, particularly when queuing or in close contact with others.
Finally, wearing a well-fitting mask that covers the nose and mouth can provide additional protection. Masks should be worn in accordance with local guidelines and regulations. It is important to follow good practices when donning and doffing masks, including ensuring the mask fits snugly and handling it only by the ear loops or ties to avoid contamination.

Disinfecting and sanitising surfaces
To effectively disinfect and sanitise surfaces in an airport setting, the following measures can be implemented:
- Identify high-touch surfaces: Focus on frequently touched surfaces such as counters, kiosks, handrails, door handles, elevator buttons, and tray tables. These surfaces are more likely to be contaminated and require regular disinfection.
- Use appropriate disinfectants: Select disinfectants that are effective against the coronavirus. Follow guidelines and recommendations from health authorities, such as using disinfectants with a certain concentration of chlorine or alcohol-based solutions.
- Establish a disinfection schedule: Develop a routine cleaning and disinfection schedule for all areas of the airport, including high-traffic zones and less accessible areas. Increase the frequency of cleaning and disinfection in busier periods or when there are higher numbers of passengers.
- Utilise technology: Implement innovative technologies, such as LED lights embedded with germ-killing properties, to continuously sanitise surfaces and reduce the presence of germs and viruses.
- Communicate with passengers: Educate passengers about the importance of sanitising their personal belongings and devices. Provide accessible sanitation stations or wipes to encourage passengers to disinfect their hands and the surfaces they come into contact with.
- Monitor and supervise: Assign dedicated personnel to monitor the cleanliness of surfaces and ensure that disinfection protocols are being followed correctly and consistently. Regularly inspect high-touch surfaces and conduct quality checks to maintain sanitation standards.
By implementing these measures, airports can effectively disinfect and sanitise surfaces, reducing the risk of coronavirus transmission and creating a safer environment for passengers and staff.

Social distancing and face masks
Social distancing and the use of face masks are two of the most effective ways to prevent the spread of coronavirus. This is especially important in airports, which tend to be large facilities that attract big groups of people from all over the world.
To ensure social distancing, airports can implement measures such as simplifying boarding formalities, setting up special passages, and assigning a designated person to monitor passengers. This helps to prevent cross-infection and allows for the proper handling of incoming passengers. It is also important for passengers to arrive at the airport early to ensure adequate time for security screening and social distancing.
Face masks are another crucial tool in preventing the spread of coronavirus. All passengers should be required to wear masks, especially those who are feverish or displaying other symptoms of COVID-19. Security officers and other airport staff should also wear masks and gloves, changing gloves after each pat-down and check of belongings.
In addition to social distancing and face masks, basic hygiene practices such as handwashing and the regular cleaning and disinfection of public areas are essential. This includes the management of waste sorting and the collection of used masks, as well as the disinfection of trash cans and other waste containers.

Food and drink safety
While it's important to eat healthy foods to maintain a healthy immune system, it's also crucial to be mindful of food and drink safety when travelling through airports to prevent coronavirus and other illnesses. Here are some tips for food and drink safety:
Firstly, it's recommended to bring your own food and drinks to the airport. This gives you more control over your snack options and can help you save money. Sealed snacks with a longer shelf life, such as nuts, granola bars, and dried fruit, are good options. Bottled, sealed drinks are also safer alternatives to fountain drinks, as the dispensers may not be cleaned properly, increasing the risk of bacterial ingestion.
If you do choose to purchase food at the airport, be cautious of perishable items, such as milk, which should not be left out at room temperature for more than two hours, according to the FDA. Pre-cut fruit from grab-and-go counters can be risky if not handled properly, as the exposed fruit can be contaminated by bacteria during handling, processing, and storage. Instead, opt for fresh fruit with the peel still on, such as apples, oranges, or bananas, which are less likely to be contaminated.
When it comes to meals, it's best to avoid raw or undercooked options, especially meat, as they carry a higher risk of food poisoning. Go for hot, cooked foods instead, as higher temperatures help reduce the presence of harmful bacteria. Fully cooked seafood dishes, grilled chicken, or plant-based proteins are safer choices. If you're craving a coffee, opt for decaf, as regular coffee contains caffeine, which can affect your energy levels and impact your sleep.
In addition to these precautions, it's crucial to maintain good hand hygiene when eating or drinking at the airport. Wash your hands frequently, especially before eating, as thousands of people touch the same airport surfaces every day. Handwashing can significantly reduce the chances of ingesting microorganisms that can make you sick.
