What’s causing the increase? According to the CDC, there are multiple factors involved. Since overseas travel and commerce are more common than ever before, germs are increasingly spreading and moving into new regions. 

“A traveler can be infected with a mosquito-borne disease, like Zika, in one country, and then unknowingly transport it home,” the CDC report stated.

In addition to travel, new germs have also been discovered and added to the list of nationally notifiable diseases.
