Communicable diseases are most often spread by microrganisms which are transferred from individual to individual by droplet contact (sneezing, kissing, etc.), sexual (bodily fluid) contact, foodborne contact, and water source contact. Sometimes skin to skin contact is sufficient, as well.
Infectious diseases are spread through various means such as direct contact with an infected person, respiratory droplets when someone coughs or sneezes, ingesting contaminated food or water, or through vectors like mosquitoes or ticks. Some infectious diseases can also be spread through blood or bodily fluids.
Noninfectious diseases are caused by factors such as genetics, lifestyle choices (e.g. diet, exercise, smoking), environmental factors (e.g. pollution, radiation), and aging. These diseases develop over time and are not spread from person to person like infectious diseases. Examples of noninfectious diseases include heart disease, cancer, and diabetes.
The key points of the germ theory of disease are that microorganisms (germs) are responsible for causing infectious diseases, these microorganisms can be spread from person to person, and that proper hygiene and sanitation practices can prevent the spread of these diseases.
Diseases can be spread by various factors including infected individuals, contaminated food or water sources, infected animals, and inadequate sanitation practices. In a broader sense, the responsibility for controlling the spread of diseases lies with healthcare systems, public health agencies, and individuals following prevention guidelines.
Volcanic eruptions can cause health issues such as respiratory problems from exposure to ash and toxic gases like sulfur dioxide. Additionally, volcanic eruptions can lead to contaminated water sources, which can spread diseases like cholera and dysentery. The disruption of communities and healthcare systems post-eruption can also contribute to the spread of various infectious diseases.
