China has been fighting a hard war against the coronavirus since the first cases were identified last December in Wuhan, the epicenter of the outbreak.

Among those working on the front line are the tens of thousands of medical workers who are risking their lives and working long hours to save lives. They are definitely this winter's most unforgettable faces.

The total number of confirmed cases on the Chinese mainland now stands at 80,651, while the cumulative death toll is 3,070. These numbers highlight how the rapidly-spreading epidemic has put a strain on medical workers struggling to stem an outbreak that has made so many suffer over the past three months.

Chinese authorities reported Friday that more than 3,000 medical staff in central China's Hubei Province have been infected with the novel coronavirus, and some have lost their lives.

Yet despite all the risks and hardship, over 40,000 medics have volunteered to Hubei Province and its capital Wuhan, from across China, to help their counterparts there to handle the patients crowding local hospitals since the beginning of the outbreak.

The untold story of the other side, however, is that many of the medics are also mothers and fathers, husbands and wives, daughters and sons, who have parted ways with their families to work amid danger.

The situation shows the extreme lengths that people who are on the front lines of this outbreak, especially the medical workers, are taking to stop the spread of the virus.

Besides, there are also volunteers who are helping stay-at-home residents, police officers who are working to help maintain order as well as ferrying patients, construction workers who built temporary hospitals within days, and deliverymen who stick to work for millions of home. These are the people who have sacrificed a lot for others and continue to do so.

Based on the true story of a six-year-old boy whose parents are both working on the front line, CGTN created this short video, to give you a glimpse of the untold story of those "unsung heroes" fighting the virus.
