The team of young soccer players rescued from a Thai cave may face greater struggles in overcoming any mental scars from their ordeal compared to their physical ailments, Australian health experts say.
The final four of the 12 boys and their coach were extracted from the flooded Tham Luang cave on Tuesday and taken to hospital to join their teammates for medical tests.
An international rescue team, including Adelaide doctor and underwater cave explorer Richard "Harry" Harris, helped rescue the weak and malnourished boys and their coach who were trapped for more than two weeks.
While Thai medical experts have described the boys as "healthy and smiling", two are suspected of having developed lung infections.
Australian experts say most people are resilient and bounce back from physically and mentally stressful events like the one endured by the Wild Boars soccer team.
However some may endure psychological side-effects that will need to be monitored.
University of Melbourne Associate Professor of child trauma and recovery Eva Alisic says the boys may have short-term issues including sleep and concentration problems.
"Other things that could come up is that they think about it all the time, or lose interest in hobbies and become withdrawn," she told AAP.
"Sometimes people may also avoid things that remind them of what happened and in this case it could be enclosed spaces, but I can't say for these individual children how they will deal with that."
The international rescue team that extracted the boys and their coach from the cave worked under immense pressure to free them.
The Australian anaesthetist Dr Harris, who risked his life to repeatedly journey into the underground cave, also has the added stress of coping with the death of his father who died soon after the last boys and their coach escaped.
Assoc Prof Eva Alisic said the rescuers could also have trouble coming to grips with the death of 38-year-old Saman Gunan, the Thai Navy SEAL who died in the cave last week.
"Usually emergency professionals are usually very resilient and used to working under high pressure but sometimes things pop up that make it harder to work through and of course losing a colleague in the process is a very stressful and sad experience," she said.
Associate Professor Allen Cheng, from Monash University's Department of Epidemiology and Preventive Medicine, says the boys also face health risks from being malnourished and possible infections.
The boys could be at risk of "re-feeding syndrome", a condition that can set in once people start eating again after their body has gone into starvation mode.
"If you feed these kids up again they can get a lot of physiological imbalances including phosphate levels in their blood falling," he said.
The boys are also undergoing tests for specific diseases including histoplasmosis, a fungal infection found mainly in caves where bats live.
