If you receive a COVID-19 diagnosis before returning home, prioritize seeking necessary medical care first. Inform your insurer immediately if you fall ill, and they will guide you on available options. Your travel insurance should cover eligible medical expenses, barring any disregard for government travel advisories. Additionally, you might be able to claim for extra costs resulting from an extended stay, such as accommodations for other members of your group. If placed under quarantine abroad, you may be eligible to claim out-of-pocket expenses. Many insurers are honoring claims for emergency medical treatment and repatriation associated with COVID-19, but it's always wise to confirm with your insurer.
