Operations resumed on Monday to rescue nine boys and the coach who remain stranded in the cave.
Four more boys and their coach remain trapped inside the Tham Luang Nang Non cave complex.
"Hooyah", the Thai Navy SEALs, who have played a crucial role in the against-the-odds operation, said in a Facebook post as they announced that a total of eight members of the "Wild Boars" football team had been rescued on Sunday and Monday.
The rescued boys are being kept in sterilized isolation units at a nearby hospital, which prohibits physical contact, and their parents have not been told they're safe.
The mission to save all the trapped is a race against the clock with heavy rain expected this week which would again flood the tunnels with fast-flowing, rising water.
The four rescued boys have been transported to a Chiang Rai hospital for treatment and medical evaluations, reported CBS.
'The doctors are evaluating when the parents and other relatives can visit the boys in hospital.
But the chances of monsoon rains sending torrents of water into the cave and making the rescue effort too risky is never far from the minds of everyone involved in the operation.
Hundreds of spectators and journalists have gathered in the area around the cave, hoping for news that the boys and their coach would emerge safely.
A diving crew is now making the treacherous journey to save the group of 13 boys aged 11-16 and their football coach who are trapped by flooded tunnels.
"You start to hallucinate, you see things, you hear things", said Dr. Robert Glatter, emergency physician at Lenox Hill Hospital.

Phuwadech Kamnguen, a 14-year-old best friend of one of the trapped boys, said he's looking forward to eating KFC with the team again.
Officials lavished praise on the Thai and worldwide divers who executed the unsafe rescue mission, guiding boys who can barely swim and have no diving experience through a treacherous 4-kilometer-long (2 1/2-mile) escape route that twisted and turned and rose and fell inside the mountain cave complex.
Each boy is being accompanied by two divers through the dark and complex cave system.
The source said the boys arrived at the chamber at 4pm after being rescued by foreign and Navy Seal divers from the ledge where they had sheltered from floodwaters for more than a week.
Thai officials had said Sunday that they were temporarily suspending the rescue effort so they could replenish oxygen supplies and other gear.
The operation on Monday went more smoothly than on Sunday and took two hours less as the practice became more refined, he said.
"The four children are well at Chiang Rai Prachanukroh hospital".
"I'm hoping for good news today", he said.
The divers also brought out touching notes for the families written by some of the trapped boys.
All ten of the boys trapped in a flooded Thai cave have been rescued.
One boy asked for a fried chicken dinner. On top of all the concerns inside the cave, Thailand's rainy season is looming.
