     As the new semester begins amidst the rainy season, young children are more susceptible to various infectious diseases due to their developing immune systems. Close interaction in classrooms often leads to the rapid spread of germs. Dr. Warunee Niwatwong recommends parents closely monitor these 6 common conditions to ensure timely prevention and care.

 

6 Illnesses & Symptoms to Monitor

1. COVID-19

     Transmitted via respiratory droplets and contact. Symptoms include high fever, fatigue, cough, and sore throat. In some cases, gastrointestinal symptoms may occur. Consistent mask-wearing and hand hygiene remain the most effective preventive measures.

 

2. Conjunctivitis (Pink Eye)

     An inflammation caused by bacterial or viral infections. It spreads easily through direct contact with eye secretions or shared personal items. If redness or excessive discharge occurs, please consult an ophthalmologist and avoid rubbing the eyes.

 

3. HFMD

     Hand, Foot, and Mouth Disease (HFMD) is common in nurseries and preschools, HFMD presents with fever, mouth sores, and rashes or blisters on the palms and soles. Frequent handwashing and disinfecting toys are vital to controlling an outbreak.

 

4. Diarrhea

     Diarrhea is resulting from contaminated food, water, or unhygienic habits. If a child experiences more than three loose stools a day or vomiting, Oral Rehydration Salts (ORS) are recommended to prevent dehydration.

 

Seek immediate medical attention if your child appears lethargic or is unable to take fluids.

 

 

5. Influenza (Flu)

     Influenza is characterized by high fever, chills, and muscle aches. Without proper treatment, it can lead to complications like pneumonia. Annual flu vaccination is highly recommended to reduce the risk of severe illness.

 

6. Dengue Fever

     Transmitted by Aedes mosquitoes. Persistent high fever without respiratory symptoms is a major warning sign. Parents should eliminate stagnant water around the home to prevent mosquito breeding.

 

Preventive Measures & Wellness Tips

     Strengthening your child's immunity through a balanced diet, adequate sleep, and regular exercise is essential. Schools should also maintain high hygiene standards by frequently disinfecting high-touch surfaces.

 

 

Your child's health is our priority. If you notice any unusual symptoms, please consult our pediatricians for an accurate diagnosis and prompt treatment.
