All 12 of the boys and their coach have been rescued following an incredible rescue mission that captured the globe.
The boys became trapped when flash floods engulfed the cave that they were exploring on June 23.
Health experts believe the boys could have been exposed to various diseases in the flood water, caused by excrement animals living in the caves.
The authorities in Thailand have confirmed that two of the rescued soccer players are showing signs of pneumonia and they remain in isolation in hospital.
It is feared that the boys may have Speleonosis, which is known as cave disease, and can cause death in extreme cases.
Cave disease can be contracted by breathing in fungus found in soil with bat or bird droppings.
Urine, blood and lung tests can detect the fungus, which may have been spread when the boys walked through the cave.
Emergency medicine resident physician in Oakland, California, Dr Petrina Craine said: “Anything that disturbs the ground like digging, or even just walking, can spread the fungus and the disease.
“Caves are known to be special breeding grounds for Histoplasmosis, with unique environments that can provide an ideal home for the fungus.
“With more than two million people each year exploring caves, or spelunking, it is becoming an increasingly common cause of infection.”
Experts have also warned that some of the team may never be able to swim, be in the dark or be a room with the doors shut again following their ordeal.
Professor Petter Leggat from James Cook University in Queensland said rat urine is the main culprit in the spread of bacterial disease in Thailand.
The professor said that it was likely that the soccer team had drunk the water in the cave so there was a possibility of leptospirosis.
There is concern that the soccer team could have contracted the tropical disease of melioidosis, which is a tropical disease caused by germs that live in wet soil and can enter the body through cuts and scratches.
Professor Leggat said: “Thailand is one of the hotspots for melioidosis.
“Certainly water would help bring that to the surface so I think it’s justifiable they could be a little bit concerned.”
The rescued boys will suffer from post-traumatic disorders according to Professor Ian Hickie from the University of Sydney’s Brain and Mind Centre.
Professor Hickie said: “The danger here for kids who are individually dragged into the limelight is that their whole life becomes about this one particular misadventure.
“I think the Thai authorities’ emphasis on privacy and trying to deal with the group as a whole is actually a very mature one, assuming the families are intimately involved.”
