You might think the COVID-19 pandemic is a thing of the past. The truth is, the virus is still circulating among us. Perhaps you have found yourself wondering, “Could this cough or fever actually be COVID-19?” For most, symptoms clear up within a few weeks, but for others, they can linger for months. Being well-informed is essential for your long-term health.
How long does COVID last? When are you infectious?
Most individuals with mild cases recover within two weeks. However, for some—especially those with underlying health conditions—the recovery process can take significantly longer.
The most important thing to understand is your window of infectiousness.
- You can be contagious starting two days before you show any symptoms.
- During the first few days of symptoms, you are at your most contagious.
- Remember, some people can carry and spread the virus without ever showing symptoms at all. This is known as asymptomatic spread.
Following CDC guidelines, the best course of action is to isolate yourself if you are ill. You may return to your normal routine 24 hours after your fever has completely resolved without the use of fever-reducing medication. Even then, it is highly recommended to wear a mask and practice social distancing for an additional 5 days to protect those around you.
How does this virus actually spread?
The virus that causes COVID-19 is primarily transmitted from person to person. Let’s look at the primary transmission routes.
| Transmission Route | In Simple Terms… |
|---|---|
| Respiratory Droplets and Aerosols | When an infected person coughs, sneezes, or talks, they release tiny droplets from their nose and mouth containing the virus. If you are within 6 feet, breathing these in can cause infection. This is the primary method of spread. |
| Surface Contact | The virus can live on surfaces like doorknobs or tables touched by an infected person. If you touch a contaminated surface and then touch your eyes, nose, or mouth, you can become infected. On materials like plastic or stainless steel, the virus can survive for 2-3 days. |
| Fecal-Oral Transmission | Viral particles have been found in the stool of infected individuals. While this is a less common transmission route, failing to wash your hands thoroughly after using the restroom poses a potential risk to others. |
Understanding Airborne Transmission
Research shows that the virus can remain suspended in the air for up to 3 hours. This means if you enter a space where an infected person was recently breathing, you could inhale viral particles. This risk is highest in crowded, poorly ventilated indoor areas.
The risk of catching COVID-19 from store-bought goods, parcels, or food is extremely low. However, it is always best practice to wash your hands with soap and water for 20 seconds before and after handling incoming packages or groceries.
Symptoms and 'Long COVID'
COVID-19 symptoms can range from a few weeks to several months, depending on your immune system, pre-existing health conditions, and the severity of the infection.
- Mild Infections: Typically involve upper respiratory symptoms like a cough or sore throat. These usually resolve in about 2 weeks.
- Loss of Taste/Smell: This symptom can persist longer for some, ranging from 2 weeks to 3 months.
- Severe Infections: Symptoms affecting the lungs can last for an extended period, sometimes 2-3 months.
What is Long COVID?
For some, various symptoms continue for months after the initial infection has cleared. Common examples include extreme fatigue, shortness of breath, joint pain, chest discomfort, and brain fog or memory issues. This is known as Long COVID. If you are experiencing long-term symptoms, please consult your doctor.
How can we stay safe? (Prevention Methods)
There are many steps you can take to protect yourself from COVID-19. Consistency is key.
- Get Vaccinated: Stay up to date with your COVID-19 vaccines and booster doses. While vaccines may not prevent infection entirely, they are highly effective at preventing severe illness, hospitalization, and death.
- Hygiene Matters: Frequently wash your hands with soap and water. If soap isn't available, use a hand sanitizer with at least 60% alcohol.
- Avoid Touching Your Face: Resist the urge to touch your eyes, nose, or mouth with unwashed hands.
- Wear a Mask: Using a mask in crowded, public, or poorly ventilated indoor settings provides significant protection.
- Practice Social Distancing: Keep at least 6 feet of distance from others, especially those showing symptoms like coughing or sneezing.
- Improve Ventilation: Keep windows open to ensure fresh air circulation. Use fans if possible, and consider using air purifiers with HEPA filters.
- Stay Home If Ill: If you feel unwell, stay home to protect those around you.
- Clean Surfaces: Frequently clean and disinfect high-touch areas like doorknobs, light switches, and your phone.
Important Advice for High-Risk Individuals
While anyone can catch COVID-19, certain groups are at higher risk for severe illness:
- Individuals over the age of 65
- Those with chronic conditions such as diabetes, heart disease, high blood pressure, or asthma
- Individuals with a weakened immune system due to conditions like cancer or other medical factors
- Individuals with severe obesity (BMI of 40 or higher)
- Pregnant individuals
If you fall into these categories, please be extra vigilant regarding safety precautions. Additionally, adhere strictly to your doctor's prescribed treatment plan. If you suspect you have been infected, contact your physician immediately.
When should you see a doctor?
If you have COVID-19 symptoms and belong to a high-risk group, seek medical advice promptly. Early intervention with antiviral medications (such as Paxlovid or Remdesivir) can significantly reduce the risk of severe disease progression.
Seek emergency medical attention immediately for these severe symptoms!
If you or a family member experience any of the following, go to the nearest emergency department or call emergency services immediately.
* Severe difficulty breathing
* Persistent chest pain or pressure
* New confusion or mental fog
* Inability to wake or stay awake
* Bluish lips or face
Do not wait at home if you experience these symptoms. Seeking emergency care promptly can save lives.
