¿Qué es la fiebre del heno?

Fiebre del heno is an allergy to pollen, though the medical term is seasonal allergic rhinitis. 1 in 4 people in the UK are allergic to pollen.

Babies and young children aren't immune to hay fever or other allergies, but research is currently limited for this age group.

Symptoms of allergic rhinitis (AR) can often go ignored and untreated, as they can be mistaken for the baby having a resfriado común, an upper respiratory tract infection, or perhaps having the pain of teething.

A runny nose is important to look ut for, since it can be a symptom of:

• Otitis media (ear infections).

• Sinusitis (infected sinuses).

• Asma.

• Developmental abnormalities of the jaw that may require orthodontic treatment.

For information on the best way to manage hay fever in slightly older children, read our article 'What works best for treating hay fever in children'.

Dr Deborah Lee of Doctor Fox Online Pharmacy explains that if a baby with AR also suffers from eccema atópico, asma, food allergies, or an allergy to insect bites/stings,it suggests that a possible hay fever diagnosis could be likely in the future.

Babies can be allergic to just one type of pollen (such as tree or grass), or they might have an allergic reaction to several pollen types. This could mean they show symptoms of hay fever from spring through until autumn.

Signs of hay fever in your baby include:

• Frequent sneezing.

• Blocked or runny noses.

• Itchy ears, throat, and/or mouth.

• Red, swollen or watery eyes.

• Dolores de cabeza.

If left untreated, hay fever in babies can impact your baby's sleep (making them more tired during the day) and make them very distressed.

Since hay fever is a seasonal allergy to pollen, symptoms tend to worsen when trees and grasses are actively reproducing in spring and summer, which increases the pollen count.

• Grass pollen is most common between May and July.

• Tree pollen is most common between February and June.

• Ragweed pollen is most common between June and September.

If you suspect your baby could have hay fever, these tips might help:

• Buying a pollen filter for your car's air vents.

• Reducing your baby's time spent outdoors during hay fever season (hay fever tends to be worse between late March and September).

• Washing your baby's face with cool water to remove any pollen after time in parks or gardens.

• Changing your baby's clothes when you come in from being outside. Wash their clothes in hot water at 60°C or above.

• Keeping windows and doors shut when you are at home.

• Vacuuming regularly to remove any potential dust mites. Using a vacuum with a high-efficiency particulate air (HEPA) filter is said to help remove at least 99.97% of dust, pollen, mould and bacteria.

• Avoiding smoking near your baby, and try to prevent them from being exposed to second-hand smoke.

• Ensuring your baby wears a wide-brimmed hat when outdoors to shield their face from pollen.

Hay fever does not have a cure, but it can be managed. Dr Lee says that los antihistamínicos - which come in liquid and tablet form - are not recommended for children under the age of 2 years in the UK. However, you can consult your GP or pharmacist, who might be able to prescribe a suitable treatment.

"Recent research has identified that fexofenadine can be used safely in children as young as one year old, so this may hold promise for the future."

In severe cases of hay fever, it has been known for children to have immunotherapy, which is a long-term treatment that involves exposing a child to small amounts of the substance they are allergic to via a skin prick. This allows them gradually to build up their tolerance and reduce their hay fever symptoms. This might be an option in the future if other medications have not worked.
