Travel insurance is a specialized insurance product intended to cover various risks associated with traveling, both domestically and internationally. Key components of travel insurance typically include:

1. Trip Cancellation and Interruption Coverage: Reimburses non-refundable travel expenses if a trip is canceled or interrupted due to covered reasons such as illness, natural disasters, or other emergencies.
2. Medical Coverage: Covers medical expenses incurred due to illness or injury while traveling. This can include hospital stays, doctor visits, and sometimes medical evacuation back to one's home country if necessary.
3. Emergency Evacuation and Repatriation: Covers the cost of emergency medical transportation to the nearest adequate medical facility or the return of remains in the event of death.
4. Lost, Stolen, or Damaged Baggage and Personal Belongings: Reimburses for personal belongings that are lost, stolen, or damaged during the trip.
5. Travel Delay: Provides compensation for additional expenses if a trip is delayed for reasons such as weather, strikes, or other covered events.
6. Accidental Death and Dismemberment: Offers a benefit to the insured's beneficiaries in the event of death or serious injury while traveling.
7. 24/7 Assistance Services: Many policies include access to a 24/7 helpline for emergency assistance, travel advice, and support services.

Travel insurance can be purchased per trip, for multiple trips over a period (multi-trip insurance), or as annual policies for frequent travelers. The cost of travel insurance varies based on factors such as the trip's length, destination, and the traveler's age and health.
