The physiotherapy clinic inside ClubVentos Jericoacoara, has teamed up with one of the largest labs in Fortaleza to provide PCR tests for departing guests without requiring them to go to Fortaleza.
Exam material will be collected in her clinic 2 days before departure, and sent to the lab for processing. Exam result will be made available by the lab via internet before departure, in Portuguese (useful for Lisbon entry) and English. Guests interested in this service should request it upon arrival. This service is not available in Icaraizinho.
Most European countries are imposing a self-quarantine (of 10-14 days at home) for residents returning from certain countries (Brazil included at the moment), except if they present a recent Covid-19 PCR type exam done less than 72h before boarding the return flight.

Instead it requires a (painless) collection of material from the nose with a special swab, which must be sent to a lab for processing.
Some countries also offer the option to make the PCR exam after arrival in your home country to interrupt the self-quarantine. You should check the rules of your country at https://reopen.europa.eu at the time of travel, because the rules are changing all the time. It is possible that by the time you finish your vacation, Brazil may have already been removed for the list of countries requiring PCR exams on return, as the Covid-19 situation improves in the country.
