Answer

Lyme disease Explanation 1. Identify Symptoms and Context The patient presents with headache, nausea, fever, and a bullseye rash after traveling to New England for a hiking trip. These symptoms and context are crucial in narrowing down the diagnosis. 2. Analyze Symptoms A bullseye rash is characteristic of Lyme disease, which is commonly associated with tick bites. Headache, nausea, and fever are also common symptoms of Lyme disease. 3. Consider Geographical Relevance New England is known for having a higher incidence of Lyme disease due to its wooded areas where ticks are prevalent. This geographical information supports the likelihood of Lyme disease. 4. Rule Out Other Options Covid-19 typically does not present with a bullseye rash. Rheumatoid arthritis is an autoimmune condition that doesn't match the acute presentation or travel history. Food poisoning usually involves gastrointestinal symptoms without a rash.
