FAQ
Frequently Asked Questions
No, it is largely historical. Modern medicine uses more specific terms like 'Plasmodium malariae malaria' to describe the same fever pattern.
It stems from Roman inclusive counting. The cycle is: Day 1 (fever), Day 2 (interval), Day 3 (interval), Day 4 (fever). The fever recurs on the *fourth* day, counting the first fever day as 'one'.
A tertian fever recurs every other day (48-hour cycle), while a quartan fever recurs every third day (72-hour cycle), based on the ancient classification of febrile periods in malaria.
