An infection caused by bacteria. The gradient of infection is very wide, ranging from acute, fulminating, life-threatening, to symptomless subclinical, and the epidemiological and public health significance similarly varies. From the public health perspective, the most important infections are mild, subclinical, and symptomless conditions that do not restrict ability to move about and mingle with others yet can be transmitted and cause more serious disease in susceptible contacts. The same applies to infections caused by other varieties of pathogens.
