MAPASTEPEC, Mexico (Reuters) - A caravan of thousands of migrants and asylum seekers from Central America and the Caribbean resumed its trek through southern Mexico on Monday, despite concerns that half of them could be injured or sick, including some from dengue fever.

Over the past week, the approximately 3,000 migrants, mostly women and children, have trekked over 100 km (60 miles) from the city of Tapachula on the Guatemalan border, struggling through sweltering heat and evening rains.
