Nowadays, we need to prepare well before traveling. It’s recommended you check with your doctor at least six to four weeks before departure and let your doctor know that you are planning a trip and the country or cities you are visiting. Make sure you can get the vaccines and medications you need, so you are somewhat protected.
Certain regions of the world have health risk areas that could potentially affect your health.
Now that we have the new virus, COVID-19, which doesn’t have a vaccine yet, I am sure there will be more restrictions in certain countries. We don’t know what countries will require a COVID-19 vaccination certificate before arrival and who knows how many people won’t get the vaccine yet because it’s too early to confirm the secondary effects the vaccine can cause. As for me, I am not planning to get the vaccine. Regardless, it’s a good idea to have a strong immune system and to prepare ahead of time by taking the right vitamins, getting some vaccines (www.vaccines.gov/who_and_when/travel) for yellow fever, typhoid, hepatitis A, etc. and probably a physical examination, and laboratory testing, to make sure you are in good shape so you can have more chances to enjoy your trip!
Some countries required medical exams for some visas and programs. Always check the country’s travel health information a month before traveling. This is also a good website for it:
Try to travel with a first aid kit and any medicines you think you may need. I traveled to a small town in Thailand once, and I needed cough medicine, but no one spoke English at the pharmacy, and I could not understand their language. Thankfully, I used my hands and signs, so they understood what I needed, and they showed me the box I should buy. Since then, I always pack my own medicine. It is better to be prepared than sorry!
