"Expert Advice: Protecting Against Malaria in Non-Endemic Areas"

A Florida resident with rheumatoid arthritis asks if hydroxychloroquine provides protection against malaria transmitted by mosquitos. The physician explains that public health measures, such as aerial and truck spraying for mosquitos, draining stagnant water, using screens, and applying mosquito repellent, are more effective in preventing malaria. While hydroxychloroquine is an effective treatment and preventive agent for malaria, its use may be limited due to resistant parasites. The reader is advised to implement other protective measures since the medication is not guaranteed protection. In another question, a person who used oxygen with a CPAP machine for sleep apnea and atrial fibrillation (AFib) asks if they can discontinue oxygen. The physician suggests discussing this with their doctor, as they may no longer need oxygen since their AFib has been resolved.
