Why do Toddler Catch Recurrent Infections?

When a preschooler starts stepping out of their safe environment – their home, they encounter a variety of elements in the atmosphere. Their bodies are not used to it and the pathogens in the environment are new to their immune system. Their immune system is still weak and immature.

Every time your toddler falls sick due to an infection, their immune system is developing, it is learning about the foreign intruder and is also learning how to fight it effectively. The next time, the body encounters this particular invader, it will remember how to fight it and in most cases prevent your toddler from falling sick due to the same infection again.

On average, a small kid experiences 6 infections per year before they turn five years old. The numbers can go up when they start pre-school or daycare. This is quite common. There is nothing alarming about these numbers.

  • In some rare cases, the child could have PID – Primary Immunodeficiency.
  • Too many infections in a single year (two or more severe infections; three or more respiratory infections).
  • Infections lasting longer than usual.
  • Toddler not responding as expected to oral medications.
  • Confined to bed for a week and missing out on regular activities.
  • Need for intravenous antibiotics.
  • Tests persistently show abnormalities.

When the above-mentioned features are noticed in your toddler, it can be categorized as recurrent infections.

Types of Infections – Bacterial and Viral Infections

Infections can be of two main categories:

1. Bacterial Infections

Bacteria live everywhere and in every condition. Be it rainy or sunny, hot or cold, dry or wet, bacteria will survive. However, bacteria can be both good and bad. We need good bacteria for the optimal functioning of our bodies. Good bacteria help make the immune system stronger and fight infections better.

The bad bacteria on the other hand, are what causes these “infections”. When the bad bacteria enter the body, they can infect any part. These bacteria come in three shapes:

  • Rod-shaped (Bacilli)
  • Spherical (Cocci)
  • Helical (Spirilla)

Modes of Bacterial Infections

Bacteria can affect you via

  • Skin
  • Food
  • Sexual transmission
  • Respiratory tract
  • Urinary tract
  • All other parts of the body

A bacterial infection might even occur when a person is suffering from a viral infection and the immune system is compromised.

2. Viral Infection

Viruses are tiny particles made of DNA or RNA and have a protein coating. Some may even have a fatty covering. Just like bacteria, there are good viruses and bad viruses. Good viruses help the human body fight infections and can also aid evolution by transferring genes. Viruses can also affect different parts of the body. During a “viral infection”, the bad virus infiltrates the body’s immune system. It then attaches itself to a host and introduces its genetic material, for reproduction. As the virus multiplies, more host cells are killed. This is why a viral infection can cause cell and tissue damage.

Some viruses stay active throughout the infection period until they are cured. Some become inactive after the initial infection period (chickenpox and cold sores viruses become inactive after the first few days of infection). These viruses can stay back in your body and lay dormant. Something can trigger them again in the future and cause new symptoms.

The Difference

Viruses and Bacteria are completely different pathogens.

  • Bacteria is larger than a virus.
  • Bacteria can reproduce on their own. Virus reproduce by infecting a host and using their DNA to replicate itself.
  • Antibiotics work on bacteria not on viruses.

What ‘Not To Do’ to Treat Your Toddler’s Infection?

When your toddler has recurrent infections, here are a few things you should NOT do, for their own safety:

1. Do Not Self-Medicate

The first and foremost thing not to do when your preschooler has repetitive infections is to diagnose and treat on your own.

You may feel it is the same as the last time, or you may be confident that you have seen it all. You might know the names of the medicines and the procedures to follow. However, do not medicate or treat without a doctor’s consultation.

Doctors will advise on what to do when the toddler has repetitive infections, in case of emergency, etc. Find out from them and only then proceed.

2. Do Not Skip Medicines

Do not skip any medicines the doctor prescribes. Follow the dosages and complete the course of medications given even if the infection subsides. Most antibiotics have a particular course to complete, to help the body get stronger and to prevent another such episode.

3. Do Not Over Medicate

If you feel the medications are not working or helping your toddler, consult your doctor. Do not give extra medicines or increase the dosage. It can be very tempting to do this when you see your little one suffer. All a parent wants for their toddler is to get better sooner. However, when you over-medicate, you are putting your toddler in more danger. Some overdosage effects might subside on their own, but some may cause severe damages.

4. Do Not Blame the Toddler

Do not blame the preschooler for falling sick. Yes, toddler will run around and do things they are not supposed to and fall sick. It can be more difficult with a tddler who has a recurrent infection. Understand the kid is suffering too. They need compassion and understanding in addition to all those treatments and medications.

When to See a Doctor For Recurrent Infections in Toddler?

If it is a young baby, you need to see the doctor every time they fall sick, unless the doctor prescribes some medicines to be given without a consultation. Recurring infections in a single area could indicate a bigger problem. The doctor can understand the seriousness and diagnose it properly only if they know about the severity and frequency.

If the infections are in different areas of the body, you cannot go with the same treatment as given earlier. You need different medicines and tests.

Consult your doctor immediately if you notice the following:

  • Your toddler is more lethargic and unresponsive than normal.
  • Your toddler is having breathing difficulties.
  • A very high fever that won’t subside with over the counter paracetamol.
  • A body part is affected badly, or activity in that area is low.

1. What Causes Bacterial Infections in Toddlers?

Bacteria causes bacterial infections. There are several bacteria that exist around us and many of those can infect your preschooler at one time or the other. Bacteria can reproduce on their own, thus spreading fast and strong. Bacterial infections can be severe and cause other health issues if not treated in time.

They can also be secondary infections – meaning, an infection started by a virus that later progressed into a bacterial infection. Toddler are given many vaccines in the initial years of their life to prevent many such bacterial infections.

2. What Causes Viral Infections in Toddlers?

Viruses cause viral infections. Viruses are smaller than bacteria and their impact on the health of your toddler is also milder. Not all viral infections are dangerous and most of them will subside on their own. Many viruses spread only during their contagious phase and are dormant after that. Viruses need a host to attach to, else they cannot survive. This is why viruses perish after a few hours on surfaces, unlike bacteria.
