Is there any way to help people infected with covid-19? i feel helpless.

Many ways: Consider volunteering remotely or in person. Some groups include: https://www.volunteermatch.org/covid19, https://www.ramusa.org/covid-19-volunteer/. https://www.redcross.org/about-us/news-and-events/news/2020/look-for-the-helpers-stepping-up-to-stomp-out-covid-19.html, or just consider giving blood, donating to a food bank or making a friendly call to some one who is ill and alone.
