预测是一种用于估计将来可能发生情况的方法，它依靠对现行趋势的外推。进行预测的方法有多种，有些是使用相对较简单的方法将历史模式外推或延伸，但是，较正规的外推统计方法通常利用数学预测模型来完成。传染病流行病学的一些既定特征使得有必要利用数学模型进行预测。其中 Prediction is a way of estimating what’s going to happen in the future, relying on extrapolation of current trends. There are several ways to make predictions, some of which extrapolate or extend historical patterns using relatively simple methods. However, more formal extrapolated statistical methods are usually done using mathematical predictive models. Some established epidemiological features of infectious diseases make it necessary to predict using mathematical models. among them
