Report of Notifiable Disease or Related Death form

Reporting form for notifiable diseases as per the South Australian Public Health Act 2011
Poliomyelitis or polio is an infection caused by the polio virus. It is a serious disease affecting the central nervous system. Infection with the poliovirus can lead to a life-threatening muscular paralysis of the body.
In the last 20 years the number of polio cases around the world has reduced. This is largely due to global vaccination programs that aim to immunise people against the poliovirus.
Countries such as North and South America, the western Pacific region (including Australia) and Europe are now all polio-free; however cases are still being reported in some parts of Asia and Africa, including cases of vaccine derived polio in Papua New Guinea in 2018.

Poliovirus infection is a notifiable condition1
People can become infected with polio primarily via faecal – oral transmission. Ingestion can occur in the following ways:
Polio can be easily transmitted when someone infected with the poliovirus has close contact with many other people, such as in day care centres and family homes.
Most people infected with the poliovirus will have no symptoms. Ten per cent of infected people may experience flu-like symptoms such as:
Less than 1% of people infected with poliovirus develop severe muscle weakness (acute flaccid paralysis) affecting the limbs, diaphragm muscle (essential for breathing), and the head and neck muscles.
The risk of permanent limb paralysis is less than 1%. Death occurs in 2 to 5% of children and 15 to 30% of adults with paralytic polio.
Cases are diagnosed on signs and symptoms; and also by a laboratory test for the poliovirus on a person’s throat secretions, faeces or CSF.
Typically 7 to 14 days with a range of 3 to 35 days.
Transmission is possible as long as the poliovirus is shed.
The poliovirus can stay in the throat for about 7 days and in the faeces for 3 to 6 weeks.
There is no cure for poliovirus infection.
Treatment focuses on managing the consequences of severe muscle weakness. This may include admission to intensive care for mechanical ventilation, and physiotherapy or antispasmodic medications to reduce muscle spasm.
The Communicable Disease Control Branch, South Australia, should be notified on suspicion or confirmed cases on 1300 232 272 (24 hours, 7 days).
Poliovirus (You’ve Got What?) is a fact sheet for patients about the causes, signs, symptoms, treatment and prevention of poliovirus.
1 – In South Australia the law requires doctors and laboratories to report some infections or diseases to SA Health. These infections or diseases are commonly referred to as 'notifiable conditions'.
