 Epidemiology skills help us to understand '''causes of disease''' and think about '''control strategies''' to prevent further cases. HPAI is important as it can cause disease and death in humans. A number of control strategies need to be used together to best prevent spread of the disease.

 == What is field epidemiology == <!--T:5-->
 {{hlbox|'''''Epidemiology '''is the study of the patterns and causes of disease in groups of animals or populations.''
 '''''Field epidemiology''' refers to applying epidemiology skills in the field - on farms and in day-to-day work to address real problems for livestock owners.''}}

 {{example|On Budi's farm, a single calf develops an abscess at the navel (where the umbilical cord attached to the calf during pregnancy). The calf gets sick and stops drinking. Pak Paimin, the para-veterinarian examines the calf, finds the abscess at the navel, cuts it open to drain the pus and treats the calf with antibiotics. The calf then makes a complete recovery.}}
 Epidemiology applies a structured approach to investigate disease and causes of disease in groups of animals (populations). The most common approach is to collect information on animals affected with a disease and similar animals that are not affected (sick animals and healthy animals). Information on these two groups is then compared looking for differences that explain why some animals are getting sick and others are not.

 {{example|Pak Paimin treats the two cows with broad spectrum antibiotic and using field epidemiology skills, advises Budi about possible reasons for how the disease occurred and about future control. Pak Paimin knows the disease can be zoonotic and advises Budi to pay attention to general hygiene (hand washing) after handling cows. Often cows can develop this disease following some stressful event such as calving or following feeding of feed that has been contaminated with faeces from other animals. Pak Paimin advises Budi to check that the animals have clean feed and water and that any animals he buys in future should be from someone who he trusts to supply him with healthy animals. All of these strategies involve a broader understanding of how salmonellosis behaves in a cattle population and will help Budi reduce his risk of salmonellosis occurring again in the future.
 The 2 sick cows should be separated from other healthy animals on the farm. All healthy cows are to be kept higher up steam along the drain line than the 2 sick cows and the calf.}}
