The coronavirus is, unfortunately, still here. But here’s some help: As of Thursday, the federal government is, again, providing up to four free rapid tests per household. They’ll begin mailing them next week. The government will also pay for shipping the tests. You can order the tests to be delivered to your home online or by calling 1-800-232-0233. One of the available tests is intended to be accessible for people who are blind or have low vision or manual dexterity, which you can order at a separate webpage or by calling the aforementioned number and following the prompts. The Food and Drug Administration has said at-home rapid tests can detect the presence of Covid-19 up to 80 percent of the time someone is infected.
