In 1545, twenty-four years after the Spanish conquest of the Aztec empire, an epidemic of a malignant form of a hemorrhagic fever appeared in the highlands of Mexico. The illness was characterized by high fever, headache, and bleeding from the nose, ears, and mouth, accompanied by jaundice, severe abdominal and thoracic pain as well as acute neurological manifestations. The disease was highly lethal and lasted three to four days. It attacked primarily the native population, leaving the Spaniards almost unaffected. The hemorrhagic fevers remained in the area for three centuries and the etiologic agent is still unknown. In this report we describe, and now that more information is available, analyze four epidemics that occurred in Mexico during the colonial period with a focus on the epidemic of 1576 which killed 45% of the entire population of Mexico. It is important to retrieve such diseases and the epidemics they caused from their purely historical context and consider the reality that if they were to reemerge, they are potentially dangerous.

It is critical to take HIV medications, particularly protease inhibitors, exactly as prescribed to reduce the risks of developing resistance. The Food and Drug Administration (FDA) recently approved a new drug, Combivir, a combination of 3TC (lamivudine) and AZT in one tablet. Combivir works by interfering with the HIV life cycle to prevent it from replicating, and is taken twice a day with or without food. Patients with low body mass, hepatitis, or liver or kidney disease should not take Combivir. Blood counts need to be monitored regularly when taking this drug. Potential side effects include headache, nausea, fatigue, diarrhea, nasal congestion, or flu-like symptoms. A phone number is provided for more information on Combivir.
