When they arrived at the hospital, a crowd of well-wishers gathered outside, cheering and applauding them just as they had done earlier when the last rescued boys and their coach were driven into the hospital emergency bay. The hospital has sent test samples from the boys to a lab in Bangkok.
On Tuesday, the final members of the team were brought out to complete the rescue, and the news has been welcomed across soccer.
Musk, the billionaire CEO of SpaceX and Tesla, Inc., vowed to help rescue efforts by designing a mini-submarine that could navigate through the cave's tight canals.
People who endure such an intense and unsafe event can go on to suffer lasting anxiety, depression and other symptoms of post-traumatic stress disorder. "We can see that everything is ok as they're eating well", he said. The boys and their coach have to spend time in isolation to protect against the spread of any possible infections they may have contracted while in the cave.

The Thai Navy SEALs have expressed their jubilation at the successful rescue of the 12 boys and their soccer coach who were trapped inside a flooded cave.
Narongsak said that rescuers were resting and replenishing oxygen tanks to store along the treacherous route the remaining boys will take out of the cave. They can spread viruses ranging from rabies to Nipah, which can cause pneumonia, seizures and death.
Officials revealed on Tuesday that the first eight boys rescued from the cavern were in good health overall and some requested bread slathered with chocolate for breakfast.
One Navy SEAL did, however, die trying to save the team which became trapped on June 23.
