Mya Thwate Thwate Khaing, who had just turned 20, had been on life support since being taken to hospital on February 9, after she was hit by what doctors said was a live bullet at a protest in the capital, Naypyitaw, NBC news reported.
"I feel really sad and have nothing to say," her brother Ye Htut Aung said.
Her death, the first among those who have protested the February 1 coup, is likely to become a rallying cry for the protesters who were again on the streets on Friday.
"I'm proud of her and I'll come out until we achieve our goal for her. I'm not worried about my safety," protester Nay Lin Htet, 24, told Reuters at a rally in the main city of Yangon.
Friday marks two straight weeks of daily demonstrations against the military's seizure of power and the arrest of elected leader Aung San Suu Kyi.
The protests in towns and cities throughout the ethnically diverse country have been more peaceful than the bloodily suppressed demonstrations during nearly 50 years of direct military rule up to 2011.
But police have fired rubber bullets several times to break up crowds.
The army says one policeman died of injuries sustained in a protest.
As well as the daily protests, a civil disobedience campaign has paralyzed much government business and international pressure is building on the military.
Police in Yangon sealed off the city's main protest site near the Sule Pagoda, setting up barricades on access roads to an intersection where tens of thousands have gathered this week.
Hundreds of people gathered at the barricades anyway, a witness said, while a procession of several thousand formed at another favored protest site near the university.
In the northern city of Myitkyina, baton-wielding police and soldiers sent protesters scattering, video on social media showed, after young people waving signs and flags drove around on motorbikes and confronted police blocking some roads.
Clashes have occurred in the town, the capital of Kachin State, over the past two weeks with police firing rubber bullets and catapults to disperse crowds.
Britain and Canada announced new sanctions on Thursday and Japan said it had agreed with India, the US and Australia on the need for democracy to be restored quickly.
Myanmar's junta has not reacted to the new sanctions.
On Tuesday, an army spokesman told a news conference that sanctions had been expected.
There is little history of Myanmar's generals giving in to foreign pressure and they have closer ties to neighboring China and to Russia, which have taken a softer approach than long critical Western countries.
Junta leader Min Aung Hlaing was already under sanctions from Western countries following the 2017 crackdown on the Muslim Rohingya minority.
"Sanctioning military leaders is largely symbolic, but the moves to sanction military companies will be much more effective," said Mark Farmaner, director of the Burma Campaign UK group, in a reaction to the sanctions.
Nevertheless, youth leader and activist Thinzar Shunlei Yi applauded the United Kingdom's asset freezes and travel bans on three generals as well as steps to stop any aid helping the military and to prevent British businesses from working with the army.
Canada said it would take action against nine military officials.
"We urge other nations to have such coordinated and united response," she wrote on Twitter.
