Traveling itself is going to help many businesses. Many tourists destinations which are remote and where locals mainly depend on the travellers need some boost. We as a community should always help by preferring to stay in homestays or guesthouses. Shopping for the stuff that is made by the locals there. And most importantly not bargaining much while doing this. We should remember that it's their main source of income and they should gain some profit too in that. Last of all, spread the word by writing blogs or making videos about it so that more people can help.
We have to take steps cautiously before planning for a trip post covid because to aggravate something that hasn't been cured completely yet will not work in longer term. Chose places where you see there is a limit set for travelers and also slowly the tourism industry will also pick its pace.
