Australia has survived an Ebola scare after a man was rushed to hospital with symptoms of the deadly virus.

The man was sent to Monash Medical Centre on Tuesday before he was transported to Royal Melbourne Hospital after he had recently returned from Africa.

He was placed in a negative pressure ventilation room in intensive care and was discharged on Wednesday when tests revealed he did not have the infection. 

'Victoria's health system has clear, well‑established protocols to manage serious infectious diseases including rapid identification, isolation, testing, and specialist care when required,' Victoria's chief health officer Dr Caroline McElnay said.

'While the risk of Ebola disease in Victoria is low, it is a serious illness, and our health system has responded appropriately to a recent low-probability suspected case.'

The man had been travelling near the Democratic Republic of the Congo (DRC) and Uganda, where a major Ebola outbreak is currently being fought.

While the man was considered low risk, Australian authorities weren't taking any chances and followed strict infection prevention and control measures.

Despite the low risk, Dr McElnay told The Age if there were an outbreak, it could cause devastating consequences.

'It is a high-consequence disease, it's got a high mortality rate,' she said.

In previous Ebola outbreaks, the virus killed more than half of those infected - many of whom died due to internal bleeding and organ failure.

This week, the World Health Organisation said 223 people died from the virus during the outbreak in the DRC while there were more than 900 suspected cases.

Experts are warning that there is no vaccine that can protect against the Ebola variant driving the outbreak - which means the virus will almost certainly continue to spread and kill.

A life-saving jab already exists to protect against the most common form of Ebola - the Zaire variant.

However, the current outbreak has been caused by a different strain, called Bundibugyo.

Symptoms of the Ebola virus include fever, muscle and joint pain, headaches, vomiting, diarrhoea and abdominal pain.

Patients will also have reduced kidney and liver functioning. The symptoms can emerge from two to 21 days after exposure.

Ebola is rare and is transmitted through contact with infected bodily fluids.

Ebola isn't the only disease that's worrying Australian health officials.

The country is currently experiencing its largest and worst diphtheria outbreak since national records began in 1991, with more than 260 confirmed cases and one death.

Roughly 94 per cent of infections have occurred among Aboriginal and Torres Strait Islander peoples.

Diphtheria chiefly affects the nose, throat, and tonsils or skin, releasing toxins that can damage organs and block airways.

It is transmitted via respiratory droplets or direct contact with infected skin lesions, sores, or bodily fluids.
