Strawbridge is in the intensive care unit at the Tupua Tamasese Meaole II Hospital Motootua in Apia.
A spokesman there today confirmed that Strawbridge was in a stable condition. He was awake but unable to speak because he was on a ventilator.
"His condition has stabilised considerably from where it was," the spokesman said.
Strawbridge, who is also a technical adviser to the Manu Samoa national team, took ill while flying to Apia ahead of Wednesday's historic All Blacks v Samoa test.
He was admitted to hospital on Tuesday night with an eye infection, but his condition deteriorated rapidly. The hospital said yesterday he was being treated with antibiotics.
The 50-year-old has now been joined by his wife, Laura, and sister Susan.
"We are touched and overwhelmed by the kindness and alofa [love] shown to us by friends and strangers and the wider rugby community," Laura Strawbridge said.
After Strawbridge took ill, an urgent call was put out for blood donors, with the message getting through to the Samoa hotel where West Coast man Ross Wylde was enjoying a drink, One News reported.
Medical staff were looking for donations of Type O-negative blood, which Mr Wylde has. He immediately switched to drinking coffee and water, and was later picked up by a doctor to donate blood.
Mr Wylde said he was a registered blood donor so had no hesitation in helping out. "Not at all, that's why we do it," he said.
Laura Strawbridge said the intensive care unit team at the hospital, "our Chiefs rugby family, our Manu Samoa aiga [family] and New Zealand Rugby have shown us open-hearted support at this extremely difficult time".
"I am also grateful to those players and coaches from both the Manu Samoa and All Blacks teams who spent time with Andrew before I arrived, making sure he wasn't without a friendly voice."
The chief executive of the rugby franchise, Andrew Flexman, said the Chiefs were also extremely grateful for the care the coach was receiving.
