Zac Efron is seen for the first time since he almost died of an infection in Papua New Guinea

Zac Efron has been seen for the first time since it emerged on Saturday that he was rushed to hospital with a deadly infection just days before Christmas.

The actor, 32, made a low-key appearance at a Vejo shop opening in Los Angeles on Saturday, hours after it emerged that he fell ill while filming a new documentary series in Papua New Guinea.

According to The Daily Telegraph, Zac was flown to hospital in Brisbane, Australia for urgent medical treatment and was finally given the all clear to fly home to the US on Christmas Eve.

Following his recent health scare, Zac cut a casual figure as he arrived at the shop opening to support his pal, and featured in some snaps posted to Instagram.

The Greatest Showman star was joined by his longtime pal Olympic swimmer Chris Dwyer for the launch of the brand which makes specialist blenders.

Zac continued to sport a thick beard, hat and sunglasses at the event which came less than a week after he flew back to LA.

The star’s health scare only came to light on Saturday when it was reported he contracted the infection while filming the documentary series Killing Zac Efron in Papua New Guinea.

Zac was thought to have come down with a ”form of ­typhoid or similar bacterial ­infection’ just before Christmas, and was flown to Brisbane on a ‘life-or-death flight’ with the assistance of medical professionals.

What is Typhoid?

This bacterial disease (Salmonella Typhi) can be spread through contaminated food, water or close contact.

Travelers can contract Typhoid through contaminated food or water in Papua New Guinea, where Zac Efron was filming his TV series.

While Typhoid is partly preventable by vaccine, it may require emergency medical care to treat if critical. 

Once treated, via antibiotics and fluid, it can resolve within days to weeks.

Symptoms include high fever, headache, stomach pain and either constipation or diarrhoea. 

After arriving in Brisbane, he was admitted to the private St Andrews War Memorial Hospital in Spring Hill ‘in a stable condition’. 

There, he received treatment for several days, before being ‘given the all clear’ by doctors to fly home to the U.S. on Christmas Eve.   

Dr Glenn McKay, Director of Medical Rescue, the organisation that oversaw Efron’s flight, told the newspaper he could not discuss patient information, but confirmed they ‘retrieved a US citizen in his 30s from PNG to Brisbane for medical attention in Australia.’  

It is believed the Hollywood actor flew to Papua New Guinea at the start of December to film Killing Zac Efron. 

The series will follow Zac as he goes ‘deep into the jungle of a remote, dangerous island, falling off the grid for 21 days’, according to The Hollywood Reporter.

After landing in Papua New Guinea, Wewak tour guide Cyril Tara shared several pictures exploring the island with Efron. 

‘I am very happy to be is guide,’ said Mr Tara on December 7 while posing with Zac. 

During his time filming, Efron was welcomed into the Kamanibit Village after arriving by canoe, before then travelling to the Pagwi Village.

‘I tend to thrive under extreme circumstances and seek out opportunities that challenge me on every level,’ Efron said in a statement in November.   

‘I am excited to explore any uncharted territory and discover what unexpected adventure awaits.’

Killing Zac Efron will stream on Quibi, a short-form mobile video platform.
