Una descripción del resfriado común y la gripe

Las palabras “frío” y “gripe” a veces se usan indistintamente cuando en realidad son bastante diferentes. Ambas enfermedades pueden hacer que te sientas mal, pero ¿cómo puedes saber la diferencia entre cada una? Y, lo que es más importante, ¿cómo puede aliviar sus síntomas?

Sobre el resfriado común

En promedio, los adultos estadounidenses tendrán de dos a cuatro resfriados por año, y los niños tendrán entre seis y 10 años. El resfriado común es la enfermedad más común en los Estados Unidos hoy en día, y también es la razón más común para las visitas al médico, sin embargo, No hay cura para ello.

Los síntomas

Los síntomas del resfriado suelen durar entre siete y 10 días. Los síntomas comienzan leves y luego empeoran gradualmente en los próximos días. Si bien un resfriado puede hacer que te sientas bastante mal, por lo general, no es lo suficientemente grave como para interferir en tus actividades diarias.

Los síntomas comunes incluyen:

  • Congestión
  • Tos
  • Goteo o congestión nasal
  • Ojos llorosos o con picazón
  • Dolor de garganta
  • Sensación de cansancio
  • Dolor de cabeza
  • Fiebre (raramente, más común en niños)

Si sus síntomas son muy diferentes a los mencionados anteriormente, es probable que tenga otra enfermedad o infección.


La mayoría de las personas no van al médico para ser diagnosticadas con un resfriado. Incluso si lo hace, se diagnosticará según sus síntomas y el examen físico, no mediante pruebas especializadas, aunque es posible que se realicen algunas pruebas para descartar otras causas de sus síntomas.


Debido a que los resfriados son virales, no se pueden tratar con antibióticos . Los medicamentos para el resfriado de venta libre pueden ayudar a aliviar los síntomas, pero la única “cura” verdadera es dejar que el resfriado siga su curso. Se irá por sí solo dentro de una semana.

If you have ever walked down the “cold and flu” aisle at your local pharmacy or grocery store, you know there are a lot of medicines out there claiming to be the one that will make you feel better. It can be overwhelming and the truth is, none of them are going to cure you. Some of them may help bring you relief from your symptoms, but the only thing that will actually make them go away is time. Of course, that doesn’t mean you shouldn’t take any of them. We have a complete guide to cold medicine that can help you figure out which options are best for you and your symptoms.

There are also medication-free ways to help yourself feel better when you have a cold (or the flu). Running a humidifier, rinsing your sinuses with saline, drinking extra clear fluids and getting extra rest can all help you feel better faster.

About the Flu

The flu is caused by the influenza virus. There are many strains of influenza, and it frequently mutates, creating new subtypes and variants. Although there are three main types of influenza—A, B, and C—only influenza A and B cause seasonal influenza symptoms. The CDC estimates that 5 to 20 percent of Americans come down with the flu annually. It can be a very serious infection that claims the lives of thousands of people each year.


Cold symptoms usually start out relatively mild. You may feel a headache starting or have an itchy throat. In contrast, the flu hits you hard and all at once. Many people describe it as feeling like they “were hit by a truck.” Although cold and flu symptoms can be similar, the symptoms of the flu are more severe and distinct.

Flu symptoms include:

  • Fever
  • Headache
  • Body aches
  • Extreme fatigue
  • Cough
  • Sore throat
  • Mild congestion—stuffy or runny nose
  • Vomiting and/or diarrhea (this is uncommon in adults, occurs more frequently in children)


If you think you might have the flu, seeking medical attention early may make a difference. There are tests that your health care provider can perform to determine if your symptoms are caused by influenza and antiviral medications that you may be able to take if you have it. Certain people are at high risk for complications from the flu and should be started on treatment as soon as possible to prevent serious symptoms, complications, or hospitalization. Among those at highest risk are pregnant women, older adults, children under age 5 and people with chronic medical conditions such as heart disease, asthma, or diabetes. If you aren’t sure whether or not your health condition puts you at high risk for flu complications, talk to your healthcare provider before you get sick, so you will have a plan if you develop flu symptoms.


The flu cannot be treated with antibiotics, but it can be prevented with the annual flu vaccine. Although flu vaccines are not 100 percent effective, they are the best protection we have against this virus. Antiviral medications can help shorten the duration of the flu if you get it and can help protect you from it if you are exposed to someone with the flu. These medicines are available by prescription only, so you’ll have to see your healthcare provider to get them. They are also only truly effective if started within the first 48 hours of the start of your symptoms. If you wait until you are on day three or four of your illness, they are unlikely to make a difference.

In addition to prescription antiviral medicines, OTC cold and flu medicine may help relieve your symptoms as well. Taking a pain reliever/fever reducer such as Tylenol (acetaminophen) or Motrin (ibuprofen) can help with fever and many of the aches and pains that come with the flu. Decongestants and expectorants can help with coughing and congestion as well. Although these medicines won’t cure your illness, they can help with the symptoms, so you don’t feel quite as bad.

How to Tell If It’s a Cold or the Flu

Determining whether it’s a cold or the flu doesn’t have to be difficult. If you know what to look for, you can usually tell if you have a cold or the flu as soon as you notice symptoms. It’s especially important to recognize the symptoms that are flu-like and notify your doctor within the first 24 hours. If you can take Tamiflu or another antiviral flu medication within 48 hours of the start of symptoms, the flu may be shorter or less severe. Just remember, if the symptoms hit you hard and fast, it’s probably the flu. If they start slowly and then get gradually worse, it’s more likely a cold.
