Chills
Escalofríos
What it means
Chills refers to feeling cold after being in a cold environment; the word can also refer to an episode of shivering along with paleness and feeling cold. Chills may occur at the start of an infection and are most often associated with a fever. They are caused by rapid muscle contraction and relaxation, which is the body's way of producing heat when it feels cold, and they often predict the coming of a fever or an increase in the body's core temperature. MedlinePlus notes that goose bumps are not the same as chills, and it lists rigors and shivering among the alternative names. Causes may include exposure to a cold environment and any infections. In Spanish the term is escalofríos.

Escalofríos is the word MedlinePlus en español uses for chills, in the masculine plural: los escalofríos. The Spanish dictionary enters the singular escalofrío as a masculine noun and marks it "U. m. en pl.", that is, used more in the plural. It defines the word as a sensation of cold, usually sudden, violent and accompanied by muscle contractions, that sometimes comes before an attack of fever. The dictionary also gives a second sense, a similar sensation produced by an intense emotion, especially terror, and it has a separate entry calofrío defined simply as escalofrío.
MedlinePlus en español glosses escalofríos as temblores and lists rigores and temblores debidos al frío among its alternative names. Goose bumps are piel de gallina, which MedlinePlus en español says is not the same as chills. Words that appear alongside the term on that page are fiebre (fever), palidez (paleness) and sensación de frío (feeling cold).

Your right to an interpreter in the United States
If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.
You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
