Monkeypox is a viral illness that is usually spread from animals to humans. Human-to-human transmission can occur through direct contact with monkeypox sores, bodily fluids, or respiratory droplets, or through contact with contaminated clothing, bedding, or common items. 


Symptoms of Monkeypox typically include a fever, headache, swollen lymph nodes and exhaustion, followed by the development of a rash over a person's body.
