Picornavirus

Picornavirus is a group of small, RNA-based viruses that can cause various illnesses in humans, such as the common cold, hepatitis A, and hand-foot-mouth disease. They are characterized by their tiny size and simple structure, which makes them highly adaptable and capable of infecting respiratory and gastrointestinal tissues. These viruses spread mainly through contact with contaminated hands, surfaces, or bodily fluids. While some infections are mild and resolve on their own, others can lead to more serious health issues. Vaccines and good hygiene practices are important for prevention against certain picornavirus-related diseases.
