There are different viruses and viral infections and they can be obtained in different ways. But the majority of viruses are transmitted through the following paths:
– Airborne;
– Fecal-oral, hand to mouth;
– Sexually transmitted;
– Direct eye contact;
– Saliva, blood, sperm, breast milk, and other body fluids;
Worth noting that not all viral infections are airborne. For instance, it’s usual for people to get common cold through droplets of saliva but HIV, hepatitis, herpes, and other viral infections are not transferred that way.
