Parents can help with simple exercises for improving balance and physical strength, Leung added. He has noticed that despite the video guidance given by schools, many parents seem to be bothered.

"They might worry they can't do it well, or simply feel it's troublesome to take the time. But, they do have to realize they are the closest ones to their children, whether there's a pandemic or not," Leung said.

Nobody can make a reasonable prediction about where this is headed, for the future. The invisible enemy, whose existence wasn't known by most of the world four months ago, has now claimed 184,000 lives. The virus has infected more than 2.6 million people globally, including over 1,000 in Hong Kong.

Some local medical experts fear the pandemic will not be contained by July in the city, and will prove a seasonal outbreak coming back year after year. For these special needs children and their caregivers, the trial is far from over.
