Infectious Disease Surveillance

Disease surveillance is fundamental to the prevention and control of communicable diseases. Surveillance is the process of gathering disease information in a systematic way to observe clues, trends, or patterns that will help with early detection of disease and control of disease outbreaks. It is the basis for planning public health action. 

Prevention

Washing your hands regularly with soap and water continues to be a key strategy for preventing the spread of germs and communicable diseases – Hand washing can reduce the potential of acquiring respiratory diseases, diarrheal infections, and skin infections.
