For this reason, most of our pollen exposure is due to pollen in the air outdoors, and thus our allergies are to wind-pollinated plants. Many trees are primarily pollinated by wind, and tree pollens are the main springtime allergen. Mold spores also contribute to spring allergies but are most bothersome in the fall.
Most of the pollen that causes allergic reactions comes from trees, grasses, and weeds. These plants make small, light, and dry pollen grains that travel by the wind. They then can find their way into your eyes, nose, and lungs, causing allergy symptoms if you have a pollen allergy.
What Allergens Are High in San Antonio?

Allergy season can start as early as January in Southern states and linger into November. If you have symptoms year-round or your allergies are worse indoors, you may be allergic to dust mites or pet dander. The key is to see your doctor and find out what's causing your symptoms.
You can have allergies and a viral infection at the same time. If you have classic allergy signs like itchy eyes and a runny nose along with COVID-19 symptoms like fatigue and a fever, call your doctor.
Symptom check: Is it COVID-19 or seasonal allergies? Also, while COVID-19 can cause shortness of breath or difficulty breathing, seasonal allergies don't usually cause these symptoms unless you have a respiratory condition such as asthma that can be triggered by pollen exposure.
Whilst the main symptoms of COVID-19 are not typically associated with the symptoms of allergies, there are cases where additional symptoms may develop such as hives/rashes, coughing/sneezing, runny nose, pinkeye or blueish toes (COVID toes), that can develop which have some overlap with allergy symptoms.
COMMON SYMPTOMS FOR ALLERGIES, COLD, FLU & COVID-19
| SYMPTOMS | ALLERGIES | COVID-19 |
|---|---|---|
| Wheezing | Sometimes | Sometimes |
| Loss of Smell | Mild | √ |
| Sore Throat | Sometimes | Sometimes |
| Nausea, Vomiting, Diarrhea | No | Sometimes |
A runny nose, facial pain, postnasal drip, and itchy eyes are common symptoms of allergies or the common cold. But itchy eyes and facial pain are not typical symptoms of COVID-19. “The most common symptoms of COVID-19 are fever, tiredness, and dry cough,” according to the World Health Organization (WHO) .
The researchers identified ten patients with COVID-19 who developed hearing loss after infection. The hearing loss ranged from mild to profound. Nine of the patients also experienced tinnitus, a ringing or buzzing noise in one or both ears.
What Does a COVID Cough Sound Like?
Oct 29, 2021
An allergy cough is a persistent cough that typically lasts longer than three weeks. You may notice it develop in the presence of certain triggers, such as pollen, dust, mold, or pet dander. Allergic rhinitis (hay fever) is an allergy triggered by environmental factors like pollen, plants, dust, and pets.
While fever, fatigue, and a dry cough are the most common symptoms of a COVID-19 infection, you may also end up with a wet mucus-producing cough if you catch SARS-CoV-2. Your lungs and airways start to produce extra mucus to clear out infections when you catch a virus like SARS-CoV-2.
Available data suggest that patients with mild-to-moderate COVID-19 remain infectious no longer than 10 days after symptom onset.
When do symptoms start after being exposed to COVID-19? Symptoms usually appear 2 to 6 days after exposure to the virus. However, it sometimes takes longer — up to 14 days — so it is recommended you wear a mask and minimize close contact with others for at least 10 days after the last day of exposure.
If you get COVID-19, you may test positive on a PCR test for several weeks after you have ceased to be infectious. With a rapid test, you may test positive for six or seven days after your symptoms have cleared.
Reinfection with the virus that causes COVID-19 means a person was infected, recovered, and then later became infected again. After recovering from COVID-19, most individuals will have some protection from repeat infections. However, reinfections do occur after COVID-19.
Immunity varies for individuals: Immune response can differ in people who get COVID-19 and recover from the illness. The FDA-authorized and approved vaccines have been given to almost 200 million people in the U.S. alone, and have strong data supporting their effectiveness.
In addition, the hope is that people who've been exposed to COVID-19 also develop an immunity to it. When you have immunity, your body can recognize and fight off the virus. People who've had COVID-19 can get sick again and infect other people. The incidence of reinfection has been relatively low.
Yes, you should be vaccinated regardless of whether you already had COVID-19 because: Research has not yet shown how long you are protected from getting COVID-19 again after you recover from COVID-19. Vaccination helps protect you even if you've already had COVID-19.
