There are two kinds of diseases:
The process by which a pathogen spreads from one host to another is known as transmission. Infections and diseases may be spread in a variety of forms.

There are two methods for preventing a disease:
To remain well, a balanced diet includes a variety of foods in appropriate quantities. It is important for a balanced body and mind. A single meal does not have any of the necessary nutrients. According to nutritionists, a healthy, well-balanced diet is important for promoting optimal health and healthy body weight. A poor diet causes malnourishment in the body, whereas an excessive diet causes weight gain, diabetes, obesity, and other diet-related diseases.
Personal hygiene includes keeping one’s body clean, consuming clean water, washing fruits and vegetables before dining, and washing one’s hands, among other things. Public sanitation applies to the correct disposal of waste and excreta, which includes waste separation and recycling, routine disinfection, and the upkeep of the city’s water reservoir. In order to avoid infections, kitchen hygiene is highly necessary.
Chemical pollutants, such as particulates, are not necessarily the source of pollution (like smoke and dust). Sound, fire, and light are all forms of energy that may pollute the environment. Pollutants are compounds that pollute the environment.
Pollution has an effect on the ecological balance, also in minute numbers. Pollutants may work their way up the food chain and through the human body.
High levels of air contamination may raise the likelihood of heart failure, wheezing, coughing, and respiratory problems, as well as inflammation of the eyes, nose, and throat. Heart attacks, asthma, and other respiratory disorders may also be aggravated by air emissions.
In this chapter, we learned about the importance of health and hygiene. We learned about the types of diseases, Bacterial And Viral Disease & Community Health and their prevention methods.
