Common carp are among the world's most widely farmed freshwater fish, providing food and livelihoods for millions of people. But across fish farms and freshwater ecosystems, they face a formidable threat: a highly contagious virus capable of causing devastating outbreaks and wipi

Com casos em alta em São Paulo e surtos nas Américas, especialistas explicam quem deve se vacinar, por que o vírus voltou a circular e o que muda para quem não sabe se está protegido

Infection rates are high, adding to concern that authorities are struggling to get to grips with the disease. O recorte ajuda a contextualizar a pauta dentro de Viagem.

Fever is one of the best-known mechanisms by which animals combat infectious diseases. Sick animals can increase their body temperature in two ways: through physiological regulation, by altering internal metabolic processes, or through behavioral changes, such as seeking warmer e

The Ervebo vaccine has proved safe and effective against the more common Zaire strain of the Ebola virus, and World Health Organization experts say early data, notably from animal trials, suggest it may also offer some protection against the rarer Bundibugyo strain, which is spre

In a world first, scientists led by a team from Stanford University have created 16 viable viruses that do not exist in nature and were designed by AI. Their experiment, which is published in Science, could help in the fight against superbugs by allowing researchers to design cus

A Sociedade Brasileira de Imunizações (SBIm) lançou a campanha Todos contra o VSR – Proteção desde o Início. O objetivo é ampliar o conhecimento de gestantes e da população sobre a importância da imunização contra o vírus sincicial respiratório (VSR), bem como fortalecer o conhec
