It is obviously not a good idea to travel during a pandemic. In most cases, doctors will definitely notgive you the green lightto do it, nor will the authorities in many regions and countries. However, if you do have to and are actually allowed to go, here are a few things to keep in mind.
First of all, consider the mode of transport you will use. One of the easiest ways to keep far from potentially infected people is to avoid public transportation and travel directly to your destination with minimal stops using your own vehicle. Traveling by air, as with any other activity that brings you close to other people, will increase the risk of being infected with the virus, so try your best to keep a safe distance from others when standing in airport lines.
Another thing to take into account is where you will stay. Accommodations where you can minimize interactions with other people are best, but the traveler committed to masks and remaining six feet from others is likely to be fine, regardless of the accommodation. It doesn't matter whether the hotel is a chain motel or a boutique inn. It's more important thatithas a good record and follows recommended guidelines.
In terms of where to eat, preparing your own food or ordering takeout would be the safest options. But it's still possible to eat in a restaurant. Important risk factors to pay attention to include the setting (outdoors over indoors), the overall size of the whole space, the number of people sharing that space with you at that time, and the amount of time you spend in that space. When possible, avoid “peak times” to minimize the number of people you share the space with, and leave as soon as you can.
