Can I get travel insurance for 5 months?

Long-term travel insurance is insurance for long trips that last three months or more, while annual travel insurance covers multiple shorter trips that happen within one year. With annual travel insurance, trips are restricted to 30-90 days, so it’s not a useful option if your trip will last any longer than that.
