You can buy a policy which will provide you with cover 24/7 for the number of weeks purchased, including while at work or at leisure. The insurance cover is restricted to countries within the Zone you selected and lower risk zones. Once you have bought cover in a Zone you are automatically covered in all the other countries in that Zone and lower-risk Zones without additional cost. For example, if you selected the Extreme zone then you will be covered in all the countries in that Zone PLUS in all the lower risk zones — High, Medium and Low.
