Computers, Laptops, Keyboards, Mice, Smart-Phones, Telephones etc. when sneezed or coughed over can harbour viruses and germs for 2 to 3 days.

When devices are used by multiple people such as co-workers or family members these germs and viruses can be transmitted to others by them simply touching that device and then touching their eyes, mouth or nose.

It is important to regularly clean hard-surfaces, including computer and electronic devices on a daily basis as the latest research from the LiveScience website states than flu-like viruses survive on hard surfaces for 48 hrs and that the (SARS-CoV-2) can live on surfaces for up to 3 days.
