Getting a tick out quickly is top priority

Hello, dear readers, and welcome to a bonus letters column. You’ve been keeping our mailboxes even fuller than usual, and we will continue to do our best to keep up.

-- How to safely remove ticks has proven to be a very popular topic. We appreciate the array of approaches that are being shared. However, some of these, despite their firm place in tick lore, are discouraged. These include coating the visible body of the tick with nail polish or petroleum jelly, or using heat to try to get the tick to exit the skin. While it’s possible these may cause a tick to eventually detach, your goal is the immediate removal of the tick with the head and body intact. Repeated testing of a variety of approaches, including folk remedies, lands firmly in favor of pointy tweezers. These let you grab even the tiniest nymph close to the skin, then, with gentle and steady pressure, gradually and safely pull it free.

-- Our tick-removal discussion continues thanks to a reader from the Ozarks in Arkansas who deals with bites on a regular basis. “Is there any danger in using tea tree oil to remove ticks?” he asks. “I put some on the sucker for a few seconds, and he backs out willingly.” Tea tree oil is generally safe when used topically. As we mentioned earlier, the goal with a tick bite is immediate removal of the intact tick. This is to prevent the transmission of disease. If your approach with tea tree oil results in immediate and complete detachment, then you have achieved the goal. However, it’s crucial that you not wait for the tea tree oil to do its job. If the tick doesn’t move, please immediately switch to the pointy tweezer/gentle tug method.

-- Due to the success of an international vaccination campaign, smallpox was considered eradicated in 1980. The disease vanished earlier than that in the United States, and in 1972, the vaccination campaign was discontinued. Now we are hearing from readers who did get the vaccine, some as long as 60 years ago, who want to know how long that immunity lasts. These questions have arisen due to the current spread of monkeypox, which is closely related to smallpox, but with milder symptoms. Because smallpox has been gone for many decades, it’s not entirely clear how long vaccine immunity persists. A small study, which was published in the New England Journal of Medicine in 2002, surprised researchers by suggesting immunity from the smallpox vaccine lasts for 35 years -- and perhaps longer. The thing to remember about monkeypox is that it spreads through close or intimate contact with the skin, bodily fluids or sores of an infected person. It is not transmitted through the air, like the flu or COVID-19.
