As winter approaches, the likelihood of encountering illnesses such as the flu, COVID-19, and RSV (Respiratory Syncytial Virus) increases. Identifying whether you are suffering from a virus or seasonal allergies is crucial, as contagious viruses necessitate different precautions than non-contagious allergies. Winter allergies remain prevalent, and knowing how to distinguish these symptoms can help in managing your health effectively.
According to the US Centers for Disease Control and Prevention (CDC), flu season typically peaks between December and February. The anticipation of flu and COVID-19 cases escalates during holiday gatherings when people congregate indoors, increasing the spread of these viruses.
There is also growing concern about RSV, particularly among vulnerable populations, such as the elderly. The CDC recommends vaccination against RSV for adults aged 75 and older, as well as for those aged 60-74 who have a significant risk of severe illness. Pregnant individuals can also receive vaccines and monoclonal antibodies to safeguard infants from severe RSV complications.
Differentiating Flu and COVID Symptoms
According to Dr. Amesh Adalja, an expert in infectious diseases at Johns Hopkins Center for Health Security, distinguishing between COVID-19 and influenza through symptoms alone is challenging due to their overlap. Both illnesses share symptoms such as sore throat, fever, fatigue, muscle aches, and cough. Notably, loss of taste and smell—a key indicator of COVID-19—has decreased in frequency since the height of the pandemic.
The timing of symptom onset can provide some indication, with flu symptoms typically appearing one to four days post-infection, while COVID symptoms may show up two to five days later. However, the symptom onset windows are similar enough that definitive differentiation often remains elusive.
Both viruses can cause severe illness in older adults and individuals with pre-existing conditions. If you’re in close contact with someone at high risk, it’s advisable to postpone visits until you’re symptom-free.
Understanding RSV
RSV often produces mild symptoms in most adults, such as a runny nose and fever, but can lead to serious respiratory issues in the elderly and infants. Vaccines against RSV are now available for older adults and pregnant individuals to help protect newborns, and some infants may receive specific monoclonal antibodies as a preventive measure.
Identifying Allergies vs. Viral Infections
It’s common for individuals with allergies to mistake viral infections for allergy symptoms. Dr. Geoff Rutledge, Chief Medical Officer at HealthTap, explains that while symptoms can overlap, certain key indicators can help differentiate the two.
If You Have a Fever, It’s Not Allergies
Fever is typically absent in cases of hay fever, which means that if you’re experiencing a fever, it’s likely a viral infection or another type of illness. However, sinus infections caused by allergies may occasionally lead to a fever.
If You’re Experiencing Itching, It May Be Allergies
Allergies generally cause itching in the eyes or nose, which is not commonly associated with viral infections. Dr. Jennifer Bourgeois from SingleCare notes that while itching can occur with viral infections, there’s an increased likelihood it indicates allergies.
Taking an At-Home COVID Test
The most reliable method to determine if you have COVID-19 is to conduct an at-home test or obtain a lab test. This is particularly important if you will be near individuals who are older or at high risk. Recently, the FDA approved new at-home tests that can detect both COVID-19 and flu.
Conducting the Antihistamine Test
In situations where you’re uncertain if you’re experiencing allergies or a cold, Dr. Rutledge suggests trying an over-
Effective Treatments for COVID, Flu, and RSV
Antiviral medications such as Paxlovid are recommended for those at risk of severe COVID-19. It is critical to initiate treatment within the first few days of symptom onset. Similarly, antiviral treatments for influenza should commence as soon as possible for at-risk individuals.
Treatment Options for Allergies
Managing allergies typically depends on specific symptoms. Dr. Bourgeois emphasizes that various allergy medications target different symptoms. Antihistamines are commonly used, but decongestants may also provide relief. Additionally, utilizing a steroid nasal spray preemptively, two weeks before allergy season, can minimize symptoms when exposure occurs.

Plain Text Version
You’re bound to encounter some type of illness this winter, but how do you tell which virus you have? And how do you know if what you’re experiencing is just allergies? It’s important to figure it out, since viruses that cause the flu, COVID-19, and RSV are all contagious, while allergies aren’t and don’t require the same social-distancing precautions. (And yes, allergies are still common during the winter.)
According to the US Centers for Disease Control and Prevention (CDC), flu season typically peaks between December and February. The anticipation of flu and COVID-19 cases escalates during holiday gatherings when people congregate indoors, increasing the spread of these viruses.

Conducting the Antihistamine Test
In situations where you’re uncertain if you’re experiencing allergies or a cold, Dr. Rutledge suggests trying an over-the-counter antihistamine. Improvement in symptoms could indicate an allergic reaction since antihistamines are effective against histamine, which is released during allergic responses.
Effective Treatments for COVID, Flu, and RSV
Antiviral medications such as Paxlovid are recommended for those at risk of severe COVID-19. It is critical to initiate treatment within the first few days of symptom onset. Similarly, antiviral treatments for influenza should commence as soon as possible for at-risk individuals.

If taking an antihistamine relieves your symptoms, it is more likely that you are experiencing allergies rather than a viral infection. However, if there’s no improvement, it could indicate that you are dealing with a virus.
Effective Treatments for COVID, Flu, and RSV
Antiviral medications, such as Paxlovid, are recommended for individuals at risk of severe COVID-19. It is crucial to begin treatment within the first few days of symptom onset for the most effective outcome. Similar guidelines apply for antiviral treatments for influenza; they should also start as soon as possible for those at risk.
Treatment Options for Allergies
Managing allergies generally focuses on addressing specific symptoms. Various allergy medications are available that target different symptoms. Antihistamines are commonly used, but decongestants can provide additional relief. Dr. Bourgeois also emphasizes that using a steroid nasal spray proactively, about two weeks before allergy season, can help reduce symptoms when exposure occurs.
