COVID-19 Basics

In a matter of mere days in early 2020, our lives were turned upside down. We read about and listened to the available information on COVID-19 and wondered how to protect ourselves against an unseen enemy. Many turned to science looking for answers, but this virus was new to everyone and the science was evolving. The resources on this page explain the science of COVID-19, how it spreads, how to protect yourself, and how scientists around the world have worked together to understand it.

What are the treatments for COVID-19?

If you think you may have been exposed to a person who has COVID-19, contact your health care provider. You can also follow these steps:

Stay home and stay away from the people you live with to prevent spreading COVID-19 to them

Get tested for COVID-19

Monitor your symptoms

If you have any of the following emergency warning signs, get medical care immediately:

Trouble breathing

Persistent pain or pressure in your chest

Confusion

Inability to wake up or stay awake

Pale, gray, or blue-colored skin, lips, or nail beds, depending on your skin tone

If you have COVID-19, your health care provider will talk to you about the best ways to treat it.

The U.S. Food and Drug Administration (FDA) has approved one drug, remdesivir, which is known by the brand name Veklury, to treat COVID-19.

Your health care provider may prescribe this medicine to treat your COVID-19 symptoms and help you get better.

Your health care provider may also recommend that you take over-the-counter medicines, like acetaminophen or ibuprofen, to reduce a fever and help you feel better.

It’s important to drink a lot of water to stay hydrated. In some cases, your health care provider may recommend that you receive intravenous fluids to stay hydrated.

It’s also important to get plenty of rest. This will help your body fight the virus.

If you are very sick, your health care provider may recommend that you receive treatment for COVID-19 in a hospital.

In some people, COVID-19 can damage the heart, blood vessels, kidneys, brain, skin, eyes, and gastrointestinal organs.

If you have any of these complications, you may receive medicines to treat them.
For example, some people may receive blood thinners to prevent or treat blood clots.

Remember that the best way to protect yourself is to avoid getting or spreading COVID-19. Some things you can do to keep yourself and others healthy include the following:

Stay 6 feet away from people who don’t live in your house

Wear a mask over your nose and mouth

Avoid crowded places

Wash your hands often

Cover your nose and mouth if you cough or sneeze

Clean frequently touched surfaces

Get a flu vaccine and get a COVID-19 vaccine

Let’s review what we just discussed and go over some of the key points:

If you think you may have been exposed to COVID-19, contact your health care provider.

Your health care provider will talk to you about the best ways to treat COVID-19.

Si cree que pudo haber estado expuesto a una persona que tiene COVID-19, comuníquese con su proveedor de atención médica. También puede seguir estos pasos:

Quédese en casa y manténgase alejado de las personas con las que vive para evitar transmitirles el COVID-19

Hágase la prueba de COVID-19

Controle sus síntomas

Si tiene alguno de los siguientes síntomas de advertencia de emergencia, busque atención médica de inmediato:

Dificultad para respirar

Dolor o presión persistente en el pecho

Confusión

Incapacidad para despertar o permanecer despierto

Piel, labios o uñas pálidos, grises, o azulados, dependiendo del tono de su piel.

Si tiene COVID-19, su proveedor de atención médica le hablará sobre las mejores opciones de tratamiento.

La Administración de Drogas y Alimentos de los Estados Unidos (FDA) ha aprobado un medicamento, Remdesivir, conocido por el nombre de marca Veklury, para tratar el COVID-19.

Su proveedor de atención médica puede recetarle este medicamento para tratar su COVID-19 y ayudarlo a mejorar.

Su proveedor de atención médica también puede recomendarle que tome medicamentos de venta libre, como acetaminofén o ibuprofeno, para reducir la fiebre y ayudarlo a sentirse mejor.

Es importante beber mucha agua para mantenerse hidratado. En algunos casos, su proveedor de atención médica puede recomendarle que reciba líquidos por vía intravenosa para mantenerse hidratado.

También es importante descansar lo suficiente. Esto ayudará a su cuerpo a combatir el virus.

Si está muy enfermo, su proveedor de atención médica puede recomendarle que reciba tratamiento para COVID-19 en un hospital.

En algunas personas, COVID-19 puede dañar el corazón, los vasos sanguíneos, los riñones, el cerebro, la piel, los ojos y los órganos gastrointestinales.

Recuerde que la mejor manera de protegerse es evitar contagiarse o propagar COVID-19. Algunas cosas que puede hacer para mantenerse a sí mismo y a otros saludables incluyen lo siguiente:

Si tiene alguna de estas complicaciones, puede recibir medicamentos para tratarlas.

Por ejemplo, algunas personas pueden recibir anticoagulantes para prevenir o tratar los coágulos de sangre:

Manténgase a 6 pies de distancia de las personas que no viven en su casa

Use una mascarilla sobre su nariz y boca

Evite los lugares con mucha gente

Lávese las manos con frecuencia

Cúbrase la nariz y la boca si tose o estornuda

Limpiar las superficies que se tocan con frecuencia

Vacúnese contra la gripe

Vacúnese contra el COVID-19
