Answer :
1. Genetic factors are those where the genetic condition of an individual is capable of increasing the probability of developing certain diseases.
Environmental factors include the diversity of environmental stresses such as population density, temperature, food and pollutants that impact human health.
Social factors are related to the interaction of groups through culture, social class and family structure, which also have an effect on population health.
Pathogenic factors, on the other hand, are those transmitted by agents such as viruses, fungi, bacteria and protozoa, which colonize a host by adhering to cells and evading immunity, generating diseases.
2. The transmission of pathogens can occur in several ways, such as contact with bodily fluids from infected people, cross-transmission or through being spread through particles in the air.
3. We can prevent the transmission of pathogens through proper hygiene habits, healthy eating, vaccination against infectious diseases and avoid contact with other people if you have a communicable disease.
4. The environment can affect personal health through climate change, pollution and lack of infrastructure that lead to less access to quality food and basic health conditions.
