Whooping cough can be fatal to babies, who may just stop breathing. It can also be very serious for older children and adults and may become pneumonia.
Often, people just think their cough is a cold, so they don't take precautions. The first three weeks of infection are the most dangerous for other people as the infected can spread the disease without even realizing they are sick, so they infect those around them. Once it gets into a group, such as a school class or workplace, it can spread rapidly.
The best answer is to be immunized as this reduces the chances of becoming infected, plus it reduces the chances that an infected person will spread it to others. Immunised people can still be infected, but immunisation may also reduce the severity of the infection.
There is currently an outbreak of whooping cough in parts of several states, particularly NSW, and especially Northern NSW, usually linked to areas where a significant number of people have not been immunized. Local councils can usually advise about local immunization programs.
Some people get jumpy about a possible reaction to the vaccine, but the risks are minor compared with the dangers of being infected with the disease, which can kill.
Personally, I tend to look suspiciously at people with a serious cough and stay away from them, just in case.
If you do get sick, go to the doctor, get treated, get a medical certificate and stay at home - don't soldier on bravely, while infecting others at work - you're not doing anyone any favours and you're putting others at risk of serious illness. Any boss who badgers a person sick with a serious illness such as whooping cough to come back to work is a stupid, irresponsible fool, in my opinion.
