看看这句话有没有语法错误

the influence of infectious diseases that are extremely dangerous and quick to have an effec。

有，主语是the influence，are extremely dangerous and quick to have an effect是修饰disease的。那谓语和宾语呢？这只是个短语。

有~

the influence...that (is )好一点。单数名词.

这句话读着怪怪的。
我的理解，句子要表达的意思是：（极其危险的）传染病的影响是它能快速传染。

把and去掉，改成is。

The influence of infectious diseases (that are extremely dangerous) is quick to have an effect。
