Which of the following is required to ensure the availability of supplementary travel insurance?

The requirement that the condition must be resolved for a certain period before application is critical to ensuring the availability of supplementary travel insurance. This stipulation is in place to protect both the insurer and the insured. When an applicant submits a claim for supplementary travel insurance, the insurer must ascertain that there are no outstanding or ongoing health issues that may result in a claim related to pre-existing conditions. If an applicant has a resolved condition, it demonstrates that the risk associated with that condition has decreased, therefore making them a more insurable risk.

This requirement serves to maintain the integrity of the insurance system by minimizing the likelihood of adverse selection, where individuals with higher risks seek insurance coverage. By enforcing a waiting period after condition resolution, insurers can better evaluate the applicant's health status and provide coverage based on current and stable medical conditions, rather than potential complications or recurrences of previously resolved issues.

Understanding this helps applicants recognize the importance of their medical history in relation to travel insurance and encourages them to maintain or seek resolution of any medical conditions prior to applying for insurance coverage.
