Smallpox spreads primarily through direct human-to-human contact, particularly via respiratory droplets when an infected person coughs or sneezes. Close physical contact with infected individuals or contaminated objects, such as bedding or clothing, can also facilitate transmission. The virus thrives in crowded conditions with inadequate sanitation, making it easier for outbreaks to occur in such environments. Additionally, the absence of vaccination can greatly increase the risk of spread.
