Final answer:
Wearing a face mask would not provide full protection during the trip, but it can offer some level of protection. Using hand sanitizer, getting vaccinated, and booking travel insurance are important steps to consider.
Step-by-step explanation:
Out of the given options, wearing a face mask would not provide protection during the trip. Face masks are primarily used to prevent the spread of respiratory droplets from the wearer to others, so they are more effective in crowded or enclosed spaces. However, masks may still provide some level of protection against certain diseases, so it is not entirely ineffective. On the other hand, using hand sanitizer frequently can help kill germs on hands and surfaces, reducing the risk of infection. Getting vaccinated against common diseases is an important step in preventing the spread of infectious diseases. Vaccines train the immune system to recognize and fight specific pathogens. Booking travel insurance can also provide protection in case of unforeseen circumstances or emergencies during the trip.
