Published:  January 10, 2024

The winter season brings with it a surge in respiratory illnesses, and this year is no exception. The United States is currently experiencing a significant virus epidemic, with the flu, Respiratory Syncytial Virus (RSV), and COVID-19 spreading rapidly. Understanding the symptoms and treatment of each illness, as well as how you can do your part to prevent the spread can ensure a healthy winter for you and your loved ones.

The Current State of the “Tripledemic” in the United States

With the onset of winter there has been a significant surge in the spread of seasonal illnesses. According to data from the U.S. Center for Disease Control and Prevention, COVID-related hospitalizations have increased 117% since the week of November 4th, 2023 to January 13th. At the same time, flu virus epidemic has seen a decline post-holidays, the surge is far from over. This fall and winter season alone, the flue has led to upwards of 380,000 hospitalizations with over 16 million people contracting the virus in a 3 month period. Similarly to that of the flu, RSV cases have also dipped post-holidays but there are still thousands of people being hospitalized due to RSV each week.

Guide to Winter Illnesses

To combat the virus epidemic, it’s crucial to understand the symptoms associated with each respiratory disease and the treatment options available. While treatment is an important part of the puzzle, prevention is still key to limit the spread of these illnesses.


COVID-19 is a highly infectious virus caused by the SARS-CoV-2 virus. Symptoms may appear 2-14 days after exposure to the virus and can be mild to severe. Some of the most common symptoms of the current strain of COVID-19:

  • Fever
  • Cough
  • Shortness of breath
  • Fatigue
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Congestion
  • Runny nose
  • Nausea or vomiting
  • Diarrhea

Although COVID-19 is a viral illness, the FDA has recently approved a handful of drugs to treat coronavirus symptoms in those who are most at risk of hospitalization and death. Some of the antiviral medications include Remdesivir (Veklury) and Molnupiravir (Lagevrio)

The best way to prevent the spread of coronavirus is to get the COVID vaccine. Getting your first, primary COVID vaccine as well as the boosters can ensure you protect yourself and those around you.


RSV is a common respiratory virus that usually causes mild, cold-like symptoms. In severe cases, RSV infection can spread to the lungs, causing pneumonia, especially in young children and adults over 60 years old. Some of the primary symptoms of RSV to look out for include:

  • Runny nose
  • Dry cough
  • Low-grade fever
  • Sore throat
  • Sneezing
  • Headache

Treatment for RSV primarily involves managing symptoms and providing supportive care. Over-the-counter medications can help relieve symptoms such as fever and congestion. It is crucial to ensure adequate hydration and rest for a speedy recovery. For children and older adults who may have difficulty breathing and inhaler and other oxygen related treatments may be given to ensure airways remain clear and function. These treatment options are provided in severe case, particularly during hospitalization.

Luckily, there are ways to prevent the contraction of RSV including immunization. These vaccinations are only recommend for adults over the age of 60, pregnant women, and infants/young children, as these are the groups most likely to experience severe symptoms.

Flu (Influenza)

The “flu” is a contagious respiratory illness caused by the influenza virus. Severe cases of the flu can lead to hospitalization due to the impact on the lungs and other airways. Some of the most prominent symptoms of influenze include: 

  • Fever
  • Aching muscles
  • Chills
  • Sweats
  • Dry cough
  • Shortness of breath
  • Fatigue
  • Runny or stuffy nose
  • Sore throat

Since the flu is a viral illness, treatment for the flu primarily focuses on managing symptoms until they subside. Over-the-counter medications can help alleviate symptoms such as fever, cough, and congestion. Rest, hydration, and maintaining good respiratory hygiene are also crucial for recovery.

The best way to prevent the flu is an annual flu shot at th beginning of the flu season in September. When a person receives the flu shot, their immune system responds by creating antibodies that remain in the body to help guard against actual flu infections.

Preventing Winter Illnesses

Prevention plays a crucial role in mitigating the spread of the flu, RSV, and COVID-19. Here are some preventive measures you can take:

  • Get vaccinated: Consult with your healthcare provider to determine your eligibility for flu, RSV, and COVID-19 vaccinations.
  • Practice good hand hygiene: Wash your hands frequently with soap and water for at least 20 seconds, especially after coughing, sneezing, or touching surfaces.
  • Avoid close contact with sick individuals: If someone around you is exhibiting symptoms of illness, maintain a safe distance or wear a mask to reduce the risk of transmission.
  • Wear masks in crowded places: Wearing masks in public places can significantly reduce the transmission of respiratory viruses.
  • Stay informed: Stay updated on the latest information and guidelines provided by reputable health organizations, such as the CDC.
