5 Common Contagious Diseases In Children

Children, with their developing immune systems, often interact closely in environments like schools, buses, and playgrounds, facilitating the easy transmission of contagious diseases. These diseases, often caused by bacteria or viruses, such as chickenpox, measles, and hand, foot, and mouth disease, spread readily among kids through saliva and mucus droplets, especially during coughing or sneezing. Delve deeper into this article to learn about the prevalent contagious diseases affecting children.

Infectious illnesses among children

Contagious diseases can easily take hold in children due to their tendency to come into close direct contact and their habit of putting toys and objects in their mouths without frequent handwashing, potentially carrying numerous germs. Additionally, children’s immune systems are not as adept at fighting infections as those of adults. Here are five prevalent contagious diseases in children:

1. Cold


The common cold stands out as one of the most prevalent contagious diseases among children. It often spreads among classmates, prompting recommendations to stay home from school on sick days. With over 200 viruses capable of causing colds or respiratory illnesses, children under six years old are particularly susceptible, experiencing colds annually, even in daycare or home settings. Older children tend to experience fewer colds but can still contract them through close contact with an infected child or exposure to coughing and sneezing. Cold symptoms typically manifest within two days of infection and can persist for about a week.

2. Conjunctivitis

Conjunctivitis, commonly known as pink eye, results in one or both eyes appearing pink due to inflamed blood vessels. Symptoms often include eye itching, a burning sensation, crusting, and involuntary tearing. Pink eye can be caused by viruses or bacteria and spreads easily from one child to another, potentially infecting other household members. While pink eye often resolves on its own, a doctor may prescribe eye drops if necessary. If your child’s eye remains red or they experience severe pain, blurry vision, or other concerning symptoms after a few days, consulting a doctor is advisable. Regular handwashing can aid in both prevention and treatment of pink eye.

3. Cough

Coughing represents another prevalent contagious ailment among children, easily transmitted through cough and sneeze droplets. Infants catching a cough can rapidly deteriorate within days. Whooping cough, in particular, poses significant contagion risk, with symptoms persisting for about two weeks, during which the child remains contagious.

4. Stomach flu

Stomach flu

Stomach flu, often stemming from viral gastroenteritis, manifests with symptoms like diarrhea, stomach pain, and vomiting. It ranks among the primary causes of diarrhea in children under five years old and can persist for up to ten days in some cases. Rapid dehydration is a concern, necessitating close attention. Stomach flu spreads through direct contact with an infected individual or by consuming contaminated food or beverages. Regular handwashing stands as the most effective preventive measure against its transmission.

5. Head lice

Head lice, minuscule parasitic insects, sustain themselves by feeding on blood from the human scalp and depositing eggs, which can prove challenging to eradicate. This issue is a prevalent concern among children, as head lice spread readily through direct head-to-head contact. While lice themselves don’t pose serious health risks, they do cause considerable itching. Treating head lice at home is possible with various remedies, although multiple applications may be necessary for complete elimination.

Fortunately, many contagious childhood diseases, when contracted, confer lifelong immunity to the affected child, although this isn’t guaranteed for every individual. Vaccinations also play a crucial role in enhancing immunity against several of the aforementioned diseases. Ensuring your child’s safety involves keeping them away from sick individuals and taking all necessary precautions.
