Urbanization has increased the risk of disease epidemics in the modern era due to factors such as densely populated cities facilitating the spread of infectious diseases, inadequate sanitation in urban areas leading to contamination of water sources, and increased global travel allowing for faster transmission of diseases between urban centers. Additionally, urbanization can lead to overcrowded living conditions and poor access to healthcare services, further exacerbating the risk of epidemics.
There are several roles:provision of clean water and sanitation,health education,running vaccination/inoculation programs,monitoring public health,coordinating national response to epidemics.
Leaf wheat rust, caused by Puccinia triticina, is the most common rust disease of wheat. Wind rust spore are blown in the wind and can infect host plants hundreds of kilometers from their source plant, which can result in wheat leaf rust epidemics on a continental scale. It is sometimes called cereal rust because it affects cereal crops.
The spread of infectious diseases across continents is called "pandemic." This term is used when a disease affects a large geographical area and impacts a significant proportion of the population. Pandemics can have widespread effects on health, economies, and societies.
when you get a disease you are said to be INFECTED by it .
this is when certain specialists pinpiont/locates disease epidemics in different areas :))

disease epidemics
Albin Holmgren has written: 'Handbook of disease outbreaks' -- subject(s): Epidemics, Communicable Disease Control, Disease Outbreaks
epidemic - a widespread outbreak of an infectious disease; many people are infected at the same time
Early in the twentieth century, severe scarlatina epidemics were common. Today, the disease is rare
Protecting the health of all citizens; tracking infectious disease and epidemics
the spread of diseases has often followed trade, migration, and pilgrimage routes.
Civilization leads to epidemics in a number of ways. Infection can be spread more rapidly because of population density, trade over larger geographic regions, and domestication of animals that could be carrying disease.

The Epidemics was created in 1986.
Viral diseases are most likely to cause epidemics. The recent H1N1 flu virus is one example of this. One other major epidemic, which is not of infectious disease origin, is the obesity epidemic in the U.S.
