The official death toll has risen to 2,275. Earlier estimates had been as high as 10,000.
The National Disaster Risk Reduction and Management Council released the figures on Wednesday. It said 3,655 were injured, with a further 80 missing.
The storm, one of the most powerful on record, hit the country’s eastern seaboard on Friday, destroying tens of thousands of buildings and displacing about 600,000.
Eight-division champion Pacquiao is in camp in the southern Philippines – only about 320km from where the storm, known as Typhoon Yolanda in the country, caused the most destruction.
His bout is due to take place on November 24 in Macau.
Pacquiao, a congressman, said in a statement: “I really want to visit the area and personally do what I can to help our countrymen who have suffered so much in this terrible tragedy, but I’m in deep training for a crucial fight so I regret I cannot go.”
He added: “I will send help to those who need it the most and I enjoin all of you to pray for our country and people in these trying times.”
