On Tuesday 20 January 2026, an inspiring Viruskenner masterclass took place, bringing together science, real-life practice and personal stories. From emerging infectious diseases to living with HIV, and from wildlife crime to careers in research, participants gained a broad and realistic view of the world of virology and infectious diseases.
The afternoon was opened by Dominique Sickmann and Wilco Zwennis, who welcomed the participants and highlighted the importance of sharing knowledge in this fast-changing field.

Viruses in a world without borders
Prof. Eric van Gorp, internist and virologist, kicked off the masterclass with an introduction to emerging infectious diseases in our “global village”. He guided the audience through the world of viruses: where do they come from, how do they spread, and why do they continue to be a challenge for public health?
To connect the topic to real life, he asked the students for current examples of infectious diseases. One of the students mentioned avian flu (bird flu). This example led to a discussion about how a virus that starts in animals can become a major problem today, and raised questions such as if and how such a virus can spread to humans, including through the air. This interactive approach showed how a virus that first seems far away can quickly become important for people all over the world.

From classroom to science
Next, Claire Fransman, PhD candidate, shared her personal story. She showed that there is not just one fixed path into science. Which study do you choose? What does doing research really mean? And what can you do with it? Her story made it clear that research is very diverse and that curiosity and perseverance are just as important as grades or titles.

Zoonoses and wildlife crime
An impressive lecture was given by Andro Vos, founder of the Wildlife Academy in Cape Town. He spoke about wildlife crime, poaching, and the direct connection to the emergence of zoonotic infections. The impact of human actions on animals and the environment became painfully clear, but Andro also showed that prevention is possible through education, protecting ecosystems, and international cooperation.

The virologist as a researcher
Daniël Aynekulu Mersha, medical doctor and PhD candidate, gave insight into the life of a virology researcher. He talked about his research on COVID-19 in people living with HIV, as well as other infections such as dengue. His story showed how clinical work and science strengthen each other and how research can directly contribute to better patient care.

Living with HIV
Rens Willemsen shared his experiences of living with HIV. The discussion covered medical progress, but also stigma, quality of life, and the importance of knowledge about the topic. His open and personal contribution made a strong impression on the audience.

Ask me anything
The masterclass ended with a lively debate and Q&A session, where speakers, coaches and participants engaged in conversation. No question went unanswered, ranging from career opportunities to social responsibility. By the end of the afternoon, participants went home with new insights, inspiration, and a clear message: viruses affect us all, but knowledge, cooperation and curiosity make the difference.
Thank you to all the students for your curiosity, enthusiasm and great questions, which made this afternoon extra special.
