I obey all the warnings recommending washing hands while dealing with dirty surfaces on the road and in the air. I’ll be taking a train trip next week and wonder if I should not only wash, but also put on gloves. Advice? JKH, New Amsterdam NY

A: If you have sore or tender skin, wear gloves. No matter what your skin condition, it’s a good idea to wear tight plastic gloves when using public transportation, especially when using public toilets. Thoroughly wash hands and gloves as often as possible in hot, soapy water. Carry an extra pair so you’re always prepared for protection.

With all the news and travel cancellations about the illness, I want to protect myself on the next trip. Should I take my vitamins? RRJ, Camden NJ

A: They may not help much, but they can’t hurt. Many frequent flyers start taking extra vitamins several days before traveling. The National Institutes of Health says no conclusive data has shown that large doses of vitamin C will prevent colds and other virus diseases, but admits it may reduce the severity or duration of symptoms. Therefore, take your vitamins, but also take health and cleanliness precautions when you travel. This includes a kit of medicated wet wipes, face mask and medications to avoid the symptoms happening to you.

My marriage ended just a year ago. Now friends and family are advising me to get out and meet new people. I’ve always enjoyed traveling, and hope seeing sights will help me deal with being single again. Advice? MMJ, Atlanta GA

Widowed since last year, I need to get out socially now. Suggestions? MPJ, Cleveland OH

A: A good way to shake off the loneliness is do a cruise. One of the best lines for special sailings is Holland America. It caters to solo travelers via its Single Partners Program, featuring hosted events for onboard singles, and special singles-themed cocktail parties and games.

Holland America also groups singles together at meals and other shipboard schedules. On sailings of 40 days or longer, the line provides male hosts to accompany single women to dinner and social events. When booking, consider the roommate matching service with fellow solo travelers of the same sex. Two Holland America ships offer dedicated singles cabins: Koningsdam has 12, and Prinsendam has three.
