picornaviruses

Picornaviruses are a family of small viruses known for causing various illnesses in humans and animals. They are non-enveloped and contain RNA as their genetic material. Common diseases caused by picornaviruses include the common cold, hand, foot, and mouth disease, and viral meningitis. These viruses are typically transmitted through direct contact, respiratory droplets, or contaminated food and water. Due to their stability in the environment and ability to spread quickly, picornaviruses are significant public health concerns, especially in crowded or unsanitary conditions.
