Difference between Asthma and Croup

Asthma and croup are two respiratory conditions that affect children and adults. Although both conditions involve the airways and can cause difficulty breathing, there are some key differences between asthma and croup.

What is Asthma?

In those with asthma, persistent inflammation causes a narrowing of the airways (bronchi). Both children and adults are vulnerable to this issue.

Symptoms − Common signs and symptoms include wheezing, coughing, and chest discomfort. In extreme circumstances, there may also be significant difficulty breathing, which may worsen over time.

Diagnosis − The condition can be diagnosed with the use of a physical examination and pulmonary function tests that demonstrate airflow restriction. Eosinophils are a kind of white blood cell that can be detected in blood tests when they are present in excess of their usual range.

Causes − Asthma may be brought on by a variety of conditions, and it does appear that genetics have a role. Environmental and dietary allergens have both been implicated as possible triggers for asthma attacks.

Risk factors and complications − Asthma appears to run in families, so having a parent or sibling with the condition raises your odds of developing it yourself. Smoking and being exposed to environmental allergens or chemical irritants can raise the risk. Individuals who are obese are also at higher risk of having the illness. Asthma may be deadly, so it's important to get treatment and keep it under control.

Prevention and treatment − There should be no exposure to environmental substances that might potentially precipitate an assault. Asthma attacks can be averted by taking precautions such as obtaining a flu shot and avoiding contact with ill individuals. Inhalers containing bronchodilators are commonly used to treat people with asthma. Adding corticosteroid drugs can be helpful since they reduce airway inflammation.

What is Croup?

Termites are a type of social insect that may be found all over the globe. Their nesting spots include the insides of tree trunks and underground tunnels with easy access to water. Termites are notoriously damaging pests because of their habit of constructing underground nests within wooden structures. They are great for the environment since they return cellulose to the natural cycle.


Warm, wet environments are preferred by termites. Vancouver, on the west coast, is the northernmost of these cities in North America. To the north, they disappear in the Canadian provinces of Newfoundland and Ontario, but they're still present in Main and the eastern provinces of Canada on the Atlantic coast. Their range in Europe is limited to the southern half of the continent, mostly between the Mediterranean and the north coast of France. In the north, they can be found in the islands of Japan and South Korea in eastern Asia.

Invasive termite species have spread all across the world as a result of international commerce. Termites from both the Pacific Islands and East Asia have been discovered in the American mainland, whereas North American termites have been discovered in Vienna, Switzerland.

The local ecosystem is more suited to their native counterparts than the invasive species. Thus, they frequently seek safety in man-made structures. This is why invading termite species pose the greatest threat. Although while only around 10% of termites are considered pests, they nonetheless do a lot of damage to homes, furniture, and other wood structures, as well as to some very essential plants. Major efforts have been made to slow their progress.


Termites live in intricate social structures with several castes because they are eusocial. There will be a couple of reproductive termites in each colony, as well as workers, soldiers, and young termites (called nymphs). When termites have not yet reached maturity, we call them nymphs. Termite nymphs can be influenced to become workers, soldiers, or reproductives by pheromones if there is a shortage of a certain caste. The reproductives may create new colonies or replace the present reproductive couple if necessary, but the workers and soldiers can't reproduce and must be replaced.

Launching colonies

Members of the termite colony's reproductive caste are those tasked with creating new termites. They have wings for their first flight, which they afterwards discard, since they must explore the outside world to select a suitable spot for a new colony. They have thick hides and enormous compound eyes. In order to start a new colony, the fertile individuals will be carried to a remote area of the nest and released into the open. While they have a little ability to fly, they rely on the wind for the majority of their travel.

Upon arrival, the male and female pair up and begin searching for a suitable nesting location. When they do, they'll start constructing a nest and laying eggs. The female will gradually gain weight until she is a massive egg laying machine, producing thousands of eggs every day. In order to ensure the survival of the colony, the king and queen will keep having children.

The colony's young are looked after and the nest is tended to by the monarch and queen at first. They will be taken over by nymphs and labourers while the king and queen focus on having children.

Other castes

Both big mandibles for fighting predators and a long, narrow nose for firing chemicals at enemies will be standard equipment for these warriors. To protect the nest, soldiers are relied upon heavily. Staff members will have pliable frames and massive jaws for eating. A worker's duties include foraging for food, constructing and repairing the nest, and preparing meals for the colony.

Termite nests

There are two main types of termite nests: those made of wood and those made of underground tunnels. In the tropics, it's not uncommon to come across termite mounds. Microclimates within the termite mounds will be warmer and more humid than the surrounding area.

Termite mounds provide a safe haven for other insects like flies and beetles. Some of these visitors really help the termites out by secreting compounds they require. Fungal mycelia are another source of nutrition for termites. Termites engage in a rudimentary type of domestication in this way.

Differences: Asthma and Croup

The following table highlights the major differences between Asthma and Croup −





Asthma is when the bronchi of the airways are inflamed.

Croup is when any part of the respiratory tract is inflamed by a virus.

Duration of the condition

Asthma is always a chronic problem that does not go away.

Croup is a short-term, acute problem that does go away.


The diagnosis of asthma is based on a physical exam, blood tests, and lung challenge tests.

The diagnosis of croup is based on the physical symptoms that are present.


Symptoms of asthma include a tight chest, wheezing, and problems with breathing.

Symptoms of croup include a barking cough that gets worse at night.


Asthma is caused by genetic factors and environmental allergens.

Croup is caused by a viral infection.


Treatment for people with asthma includes using inhalers that have corticosteroids and bronchodilators in them.

Treatment for people with croup includes the use of humidified cool air, oxygen, corticosteroids, and epinephrine.


Asthma and croup are two respiratory conditions that can cause difficulty breathing. Although both conditions affect the airways, there are some key differences between asthma and croup, including the cause of the symptoms, age group affected, symptoms, and treatment.

It is important to seek medical attention if you or your child is experiencing difficulty breathing to determine the underlying cause and receive the appropriate treatment.
