Abstract
Worldwide, to reduce the impact of any infectious disease, it is necessary to understand the transmission dynamics of infectious diseases, to ensure timely implementation of cost-effective and evidence-based public health measures. The secondary attack rate (SAR), estimates the probability of disease transmission to an individual who has been exposed to an infectious case. In conclusion, the epidemiological indicator - secondary attack rate – is a sensitive tool for the policy makers to reduce the incidence of new cases of an infectious disease, especially in household settings.
