On the Ministry of Health website - in the "GUIDELINES ON DISORDERS"  section - it is possible to consult relevant information about vaccines required for entry into countries, as well as identify what are the official guidelines to prepare for your trip in a safe manner and in compliance with the public health protocols.

The International Certificate of Vaccination or Prophylaxis (CIVP) is the official document that proves immunization and can be issued online through the service available on the gov.br website - in the Health and Health Surveillance section. By accessing the website you can start issuing your CIVP and also consult the list of countries that require this certification.

Always be aware about the safety and quality of what you eat or offer to children to avoid health problems associated with contaminated food or water. 
Some bird and mammal species can also transmit infectious diseases, even in urban areas. Therefore, avoid close contact with live or dead birds. 

If you are attacked by domestic or wild mammals, immediately wash the affected area with soap and water and seek medical attention.

New influenza viruses circulate every year. That's why vaccination is annual. Eating well, adopting healthy and hygienic habits, and avoiding stress are the most effective forms of prevention.

After returning from your trip, if you experience fever or other symptoms such as diarrhea, skin problems, or respiratory issues, seek immediate medical attention and inform the healthcare provider about the regions you visited.

It is important to be aware of the health precautions that need to be taken in advance. Consult your doctor for an evaluation, especially if you have any pre-existing medical conditions. 

Avoid traveling while you have any acute infectious illness. If you need to take medication during the trip, obtain a prescription from your doctor and carry it with you. Remember to have an adequate supply of medication for the entire trip.
