Trinity to deliver lecturers online for rest of semester
Trinity College Dublin (TCD) is to conduct all lectures online for the rest of the semester in an effort to slow the spread of the Covid-19 virus.
Further measures may be necessary in the future, the university said in a statement.
From tomorrow morning, all lectures will be delivered online instead of in a lecture hall but tutorials, seminars and laboratory practicals will continue to be given in their current format.
"This will allow Trinity to maintain continuity of teaching and learning while minimizing the need to bring together students in large groups," TCD said in a statement.
In addition, access to the Book of Kells exhibition and the Old Library, the Science Gallery and the Douglas Hyde Gallery has been stopped as of this afternoon.
Both of these measures are being taken in the interests of your health and well-being and to decrease any potential impacts on the larger community.
"The decisions are based on the concept of social distancing which has been recommended by many experts. Our goal is to decrease the number of instances that lead to students, staff, and visitors coming together in large groups in close proximity with each other."
