Cold, Flu, RSV, or COVID-19? Let's get to know these childhood illnesses (Childhood Respiratory Illnesses)

Your little one suddenly has a sore throat, cough, and high fever. You can't tell if this is just a common cold, or if it's the flu that's all the rage these days, or if it's RSV, or COVID-19? In fact, all of these illnesses are caused by viruses that infect our respiratory tract. They can be easily transmitted from one another, and the symptoms are very similar, so it can sometimes be difficult to know exactly which illness it is. So, if your child gets sick, let's talk today about the differences between these illnesses and how to recognize them.

Let's first look at the common cold.

Simply put, this is the disease that we get all the time, but it's not that serious.

What are the characteristics of this?

The symptoms of a cold are usually very simple. The main symptoms are a scratchy throat, a runny nose, a stuffy nose, and sneezing . Even if you have a fever, it is not very severe, just a little chilly. Imagine, sometimes a child with a cold plays well, has a good appetite, and is running around. That means he does not feel much discomfort.

What are the tests and treatments for this?

There is no specific test for a cold, and there is no specific medicine. It usually gets better on its own in a few days. All we need to do is make sure they get plenty of rest and drink plenty of fluids.

Can't you prevent catching a cold?

There are countless types of viruses that can cause the common cold. That's why there is no specific vaccine for it. However, simple things like washing your hands thoroughly with soap and water, covering your mouth with a tissue or your elbow when coughing or sneezing, and staying away from people who are sick can greatly reduce the spread of the virus.

So what is this flu or influenza?

The flu is also caused by a virus, called the influenza virus. It can be a little more severe than a cold.

What are the symptoms of the flu?

The flu can sometimes come and go easily. But it is often more severe for a child than a cold. It is often accompanied by a sudden onset of high fever, chills, headache, and body aches . It can also be accompanied by a sore throat, runny nose, and cough. The child may be very upset, tired, and may lose their appetite. Some children may also have symptoms such as stomach aches, nausea, vomiting, or diarrhea.

What tests and treatments are available for the flu?

A doctor can do a flu test to confirm the flu. Most children can get better at home by drinking plenty of fluids, resting, and keeping them comfortable. However, in some cases, especially if the illness is mild or if the child has other illnesses, a doctor may prescribe an antiviral medication to help reduce symptoms and speed up the recovery. If the illness is severe, such as difficulty breathing, the child may need to be hospitalized.

Is there no way to avoid the flu?

Yes! Getting the flu vaccine every year can go a long way toward preventing this disease. This vaccine is made every year to match the latest strains of the virus.

What kind of disease is this RSV? (Respiratory Syncytial Virus)

RSV – which stands for Respiratory Syncytial Virus – is another virus that affects the respiratory system.

What are the symptoms of RSV?

RSV infection usually starts with cold symptoms. However, it can be more severe, especially in babies under 6 months and children under 2 years of age. If this happens, it can lead to bronchiolitis – an infection of the small airways in the lungs – or pneumonia. When RSV is present, babies may have fever, cough, wheezing, and difficulty breathing . They may also breathe very quickly, make a wheezing sound when breathing, and have chest retractions. They may also be less likely to breastfeed and be very sleepy. These are symptoms that should not be taken lightly.

Tests and treatments for RSV

Most of the time, doctors diagnose the illness by listening to the symptoms and examining the child. Sometimes, nasal fluids can be tested to find the virus. Most children with RSV recover on their own within a few days. However, if the illness is severe, especially if there is difficulty breathing or difficulty eating or drinking, they may need to be hospitalized and given oxygen or IV fluids .

Ways to protect yourself from RSV

Fortunately, there are now ways to protect against RSV. Pregnant mothers can get an RSV vaccine between 32 and 36 weeks of pregnancy . This will also protect their babies. If the mother has not received the vaccine, babies under 8 months of age can be given an RSV antibody shot before or during the RSV season . Also, some babies between 8 and 19 months of age who are at higher risk of serious complications from RSV (for example, those born prematurely or those with heart disease) can get a second shot before their second RSV season. Ask your doctor about this.

Now let's talk about COVID-19.

This is a name we've all heard and are familiar with by now, isn't it? This is also a disease that comes from a group of viruses called Coronavirus.

Symptoms of COVID-19

When children get COVID-19 , they may not have any symptoms at all , or they may have very mild symptoms, like a common cold. Some may have more severe symptoms, like the flu. So the symptoms of COVID-19 that you may see can be very similar to the symptoms of a cold, RSV, or the flu. But sometimes there can be different symptoms . For example, loss of taste, smell, and skin rashes .

Sometimes, a few weeks after the virus enters the body, symptoms can appear with a condition called Multisystem Inflammatory Syndrome in Children (MIS-C) , which causes inflammation in various body systems. Also, rarely, symptoms can persist, known as Long COVID or Post-COVID-19 condition.

COVID-19 Diagnosis and Treatment

To see if someone has COVID-19, doctors can do a test that looks for parts of the virus in a sample taken from the respiratory tract, called a Rapid Antigen or PCR test. They can also do a blood test that looks for antibodies that have been produced in the body to see if they have had it before.

Most people with mild illness, including children, do not need any special treatment. They can get better with plenty of fluids, rest, and fever-reducing medications (e.g., paracetamol). However, for a small number of people who are at higher risk of getting very sick from COVID-19 (e.g., children with weakened immune systems or other chronic illnesses), antiviral medications may be given to prevent them from getting very sick and needing to be hospitalized.

Some people who are very sick with COVID-19 will need to be hospitalized, possibly in an intensive care unit (ICU). Doctors can take good care of them, give them oxygen or IV fluids if needed, and treat any problems. Rarely, they may also give them antiviral drugs or steroids. If someone needs it, they may be put on a ventilator to help them breathe.

Protection from COVID-19

Everyone 6 months and older should get their COVID-19 vaccines properly, meaning they are given the approved doses. They protect against currently circulating virus variants and are very effective in preventing severe illness, hospitalization, and death from COVID-19.

When should I see a doctor?

This is the most important thing. If you have any questions or concerns, it's best to call a doctor right away. An illness that looks like a cold could be the flu, RSV, or COVID-19. Also, other illnesses caused by bacterial infections, such as strep throat or pneumonia, can have similar symptoms, but the treatments for them are completely different.

Sometimes it's hard to know exactly which germ is causing the problem. Doctors may run several tests to find out. Sometimes you can be infected with two viruses at the same time, or one after the other.

Remember, the effects of these illnesses can vary depending on the age of the child. Especially if the baby is a few months old, it is wise to see a doctor immediately for even a minor illness.

If you have these symptoms, see a doctor immediately!

If your child has one or more of the following symptoms, seek medical advice immediately:

• If the child's condition seems to be getting worse
• If you have difficulty breathing (rapid breathing, wheezing, chest tightness)
• High fever, especially if the fever does not go down despite fever-reducing medication
• If you have a severe headache
• If you have a severe sore throat, you can't even swallow.
• If the child seems confused, disoriented, or excessively sleepy
• If you have a severe stomach ache
• If you feel chest pain or pressure
• If it's hard to stay awake
• If your lips or face appear blue

If your child has asthma or another chronic illness, call your doctor right away if they start to feel sick, like they have the flu or COVID-19 symptoms. The doctor may decide to run some tests or start a special medication.

What else do we need to know?

The things we usually do to prevent the spread of germs can also help protect us from all of these viruses. It is very important to do these things regularly:

• Wash your hands often and thoroughly. Wash your hands with soap and water for at least 20 seconds, or use a hand sanitizer that contains at least 60% alcohol. Teach this habit to your little ones too.
• Stay away from people who appear to be sick, especially young children.
• Clean frequently touched surfaces (such as doorknobs, counters, toilet seats, toys, phones) thoroughly with a disinfectant solution at least once a day.
• If your child is sick, keep them home as much as possible. This will reduce the risk of spreading the illness to others.

So, what is the most important thing we need to remember from all of this?

So, moms and dads, all four of these illnesses can affect young children, and the symptoms can be similar, so it can be difficult to recognize them sometimes. However, the most important thing is to talk to a doctor immediately if you have any doubts or fears about your child, or if your child is behaving in an unusual way. Don't panic, but don't delay. A doctor can find out exactly what's wrong and give you the necessary treatment.

How much better it is to talk to a doctor and free your mind than to think to yourself, "Oh, what happened to my child?"

Also, the best ways to protect yourself from all these diseases are to follow the health habits we talked about (washing hands, staying away from sick people) and to get the necessary vaccines on time. Protecting our little ones from diseases is the biggest responsibility of all of us, right?
