Medical experts say while coughs and high temperatures are the major symptoms to look out for, they're by no means to only ones. Others include digestive problems, such as diarrhea, as well as headaches. There are also reports of victims suffering from vision problems, similar to pink eye. For now, the disease is mainly spread through the respiratory tract. Experts believe the incubation period to be between one and 14 days, meaning you could have it without knowing, and you could also be passing it on.
