The main factors that contribute to the spread of diseases include crowding, poor hygiene, lack of access to healthcare services and sanitation facilities, overuse of antibiotics, animal-to-human disease transmission, and environmental degradation. In addition to these physical environmental conditions that contribute to the spread of disease, other factors such as poverty and war contribute to an environment where diseases have increased opportunity for spread.

The main factors that contribute to the spread of diseases are inadequate sanitation, overcrowding, poor nutrition, physical weakness, lack of access to health care services and lack of hygiene education. Governance issues such as poverty and corruption also create conditions where diseases can thrive. Inadequate medical resources cause delays in treatments or missed diagnosis completely undermining public health systems. Environmental disasters brought on by climate change have a major impact on disease transmission rates as well. Warfare creates large migrations of people who are generally more susceptible to infectious diseases due to their reduced physical conditioning and disrupted access to medical care. Finally, transportation networks provide efficient ways for different strains of pathogens from all over the world to come into contact with each other and facilitate their rapid global spreads; this is especially applicable for new pathogen strains emerging from wildlife such as viruses like Ebola or West Nile.[17]
