In my personal view, it would depend on the situation. As mentioned in the discussion, if it is a crisis period like COVID-19, that is a definite share with anonymizing the data. Sharing data has many benefits since it helps with analysis and research which could contribute to new ideas and solutions for public health problems. Such collaboration enhances solving challenges and improves the decision-making process faster.
But it is also crucial to follow the regulations for data protection as we have many experiences of cyber security threats faced by developed countries. We must respect everyone’s privacy and their data should be protected by laws and regulations.
