This is not a right. When you live in a society, you assume the natural risks inherent in that social condition. Other people must also live their lives, which means possibly infecting others with communicable diseases. You might have a case if they purposefully infect you, showing a malicious intent. But, otherwise, being exposed to disease is part of the struggle with nature.
In a pandemic, though, the risk might be so extreme that it constitutes a national emergency to the proper functioning of society itself. In emergencies it's not always clear how best to get out of them. Extreme measures, including restrictions on freedoms, are sometimes necessary, when simply interacting with others might increase the problem.
I don't blame Trump for failing to protect people from the Wu. It's like blaming him for failing to protect people from hurricanes and earthquakes. There was only so much Trump could do under our system of government. Mostly it's the state and local leaders' responsibility to deal with diseases spreading in their regions.
