Either let it expire, don't go.

Don't touch your face, wash hands often, keep distance from others as you can; When you get home wash clothes, take a shower and wipe things down with bleach solution.
If you are under 60 in good health COVID19 has a mortality rate (TBD) that is very low (likely sub sub 1%) and very survivable. Most infected have mild symptoms for a few days or even asymptomatic, never really sure they had it (unless tested).
Not saying your concerns are not warranted but risks are pretty low depending on your area. Sparsely populated areas of course have less infections than densely populated areas. We will know more in another week if we peak and new cases and deaths level off.

Seriously if you have any immunity or respiratory issues you are at higher risk of complications. COVID19 causes in some people massive inflammation in lungs which leads to organ failure. Some people are more prone to this than others. As you age your immunity system declines. Average age of people who died in Italy as of early March from COVID19 in one study was 81 and all had one or more existing underlying medical issue. Use your best judgement and hygiene.
