Wherever you’re walking in desert areas, particularly between April and October, keep a lookout for rattlesnakes. You’re likely not to have any problems if you maintain distance from snakes that you see—they can strike only half of their length, so a 6-foot clearance should allow you to remain unharmed, especially if you don’t provoke them. If a rattler bites you, don’t panic. Get to a hospital within two to three hours of the bite. Try to keep the area that has been bitten below heart level, and stay calm, as increased heart rate can spread venom more quickly. Keep in mind that 30% to 40% of bites are dry bites, where the snake uses no venom (still, get thee to a hospital). Avoid night hikes without rangers, when snakes are on the prowl and less visible.
Scorpions and Gila monsters are no less of a concern, though they strike only when provoked. To avoid scorpion encounters, look before touching: never place your hands where you can’t see, such as under rocks and in holes. Likewise, if you move a rock to sit down, make sure that scorpions haven’t been exposed. Campers should shake out shoes in the morning, since scorpions like warm, moist places. If you’re bitten, see a ranger about symptoms that may develop. Chances are good that you won’t need to go to a hospital. Children are a different case, however: scorpion stings can be fatal for them. Always try to keep an eye on what they may be getting their hands into to avoid the scorpion’s sting.
Gila monsters are relatively rare and bites are even rarer, but bear in mind that the reptiles are most active between April and June. Should a member of your party be bitten, it’s most important to release the Gila monster’s jaws as soon as possible to minimize the amount of venom released. This can usually be achieved with a stick, an open flame, or immersion of the animal in water.
A novel coronavirus brought all travel to a virtual standstill in the first half of 2020. Although the illness is mild in most people, some experience severe and even life-threatening complications. Once travel started up again, albeit slowly and cautiously, travelers were asked to be particularly careful about hygiene and to avoid any unnecessary travel, especially if they are sick.
Older adults, especially those over 65, have a greater chance of having severe complications from COVID-19. The same is true for people with weaker immune systems or those living with some types of medical conditions, including diabetes, asthma, heart disease, cancer, HIV/AIDS, kidney disease, and liver disease.
Starting two weeks before a trip, anyone planning to travel should be on the lookout for some of the following symptoms: cough, fever, chills, trouble breathing, muscle pain, sore throat, and new loss of smell or taste. If you experience any of these symptoms, you should not travel at all.
And to protect yourself during travel, do your best to avoid contact with people showing symptoms. Wash your hands often with soap and water. Limit your time in public places, and, when you are out and about, wear a cloth face mask that covers your nose and mouth. Indeed, a mask may be required in some places, such as on an airplane or in a confined space like a theater, where you share the space with a lot of people.
You may wish to bring extra supplies, such as disenfecting wipes, hand sanitizer (12-ounce bottles were allowed in carry-on luggage at this writing), and a first-aid kit with a thermometer.
Given how abruptly travel was curtailed in March 2020, it is wise to consider protecting yourself by purchasing a travel insurance policy that will reimburse you for any costs related to COVID-19-related cancellations. Not all travel insurance policies protect against pandemic-related cancellations, so always read the fine print.
This underestimated danger can be serious, especially considering that one of the first major symptoms is the inability to swallow. It may be the easiest hazard to avoid, however; simply drink every 10–15 minutes, up to a gallon of water per day when outside in summer, and keep well hydrated other times of year, too, as even cool winter days can be very dry.
Temperatures in Arizona can vary widely from day to night—as much as 40ºF. Be sure to bring enough warm clothing for hiking and camping, along with wet-weather gear. It’s always a good idea to pack an extra set of clothes in a large, waterproof plastic bag that would stay dry in any situation. Exposure to the degree that body temperature dips below 95ºF produces the following symptoms: chills, tiredness, then uncontrollable shivering and irrational behavior, with the victim not always recognizing that he or she is cold. If someone in your party is suffering from any of these symptoms, wrap him or her in blankets and/or a warm sleeping bag immediately and try to keep him or her awake. The fastest way to raise body temperature is through skin-to-skin contact in a sleeping bag. Drinking warm liquids also helps.
Wear a hat and sunglasses and put on sunblock to protect against the burning Arizona sun. Try to minimize your sun exposure during the peak hours of noon to 4 pm, and watch out for heatstroke. Symptoms include headache, dizziness, and fatigue, which can turn into convulsions and unconsciousness and can lead to death. If someone in your party develops any of these conditions, have one person seek emergency help while others move the victim into the shade and wrap him or her in wet clothing (is a stream nearby?) to cool down.
