Modern outbreaks of infectious diseases Many infectious diseases are rare or not around anymore, thanks to vaccination.

New research is happening all the time so we can understand more about the disease, including the long-term effects. Flu , chicken pox , whooping cough , measles — these diseases still have occasional outbreaks in Australia, mainly when introduced from overseas. They could make a strong comeback if people stop vaccinating.

In January , 62, measles cases were notified globally compared to the same period in when only 23, cases were notified. There is ongoing evidence of transmission throughout the Americas, Africa and other regions of the world. As of , a total of 86 countries and territories have reported evidence of mosquito-transmitted Zika infection. Ebola — the latest outbreak of Ebola virus disease started in Democratic Republic of Congo in August , and is ongoing.

British Columbia Specific Information Immunizations, also known as vaccinations, help protect you from getting an infectious disease. Top of the page. Topic Overview An overwhelming majority of health professionals, medical researchers, and professional medical organizations such as the Canadian Paediatric Society and the College of Family Physicians of Canada recommend immunization.

Vaccinations prevent you or your child from getting diseases for which there are often no medical treatments. These illnesses can result in serious complications and even death. A small number of people may be susceptible to diseases, such as those with impaired immune systems. These people may not be able to get vaccinations or may not develop immunity even after having been vaccinated.

Their only protection against certain diseases is for others to get vaccinated so the illnesses are less common. If exposure to a disease occurs in a community, there is little to no risk of an epidemic if people have been immunized. Related Information Immunizations.

Previous Section: Related Information Top of the page. Current as of: August 31, What is immunisation? Immunisation is a simple and effective way of protecting children from serious diseases. It not only helps protect individuals, it also protects the broader community by minimising the spread of disease.

Vaccines work by triggering the immune system to fight against certain diseases. If a vaccinated person comes in contact with these diseases, their immune system is able to respond more effectively, preventing the disease from developing or greatly reducing its severity.

These diseases can cause hospitalisation, serious ongoing health conditions including cancer, brain damage and deafness and are sometimes fatal. High immunisation rates in the community have led to many of these diseases becoming rare. However, they still exist and the risks of side-effects or complications from these diseases are far greater than the very small risks of side effects from vaccination.

The National Immunisation Program Schedule recommends certain vaccinations at certain times. These vaccines are available free of charge for all Australian children. Childhood immunisations are recommended at birth, two months can be given at six weeks , four months, six months, 12 months, 18 months and four years can be given at 3 years 6 months. You can obtain the latest schedule information by talking to your immunisation provider, calling 13 HEALTH 13 43 25 84 or visiting Immunisation.
