Asthma
As a common and long-term health condition, the severity of asthmatic symptoms may change depending on the child. It affects their airways with a sudden and severe onset of symptoms such as the difficulty to breathe, wheezing and shortness of breath.
A sudden, severe onset of symptoms is known as an asthma attack.
Bronchiolitis
Bronchiolitis is a lower respiratory tract infection that affects babies and children under two years old. Bronchiolitis affects bronchioles (smaller airways). It is caused by a virus called RSV (respiratory syncytial virus).
Symptoms of bronchiolitis include:
Chickenpox
A mild disease and a rite of passage for many, chickenpox is a disease that most children will catch at some point. Caused by the varicella-zoster virus, chickenpox is highly contagious and can be passed onto others about 2 days before any symptoms have shown.
It is best to keep your child away from public areas within 10-21 days after being near someone who has chickenpox.
Symptoms of chickenpox include:
Getting the chickenpox (varicella) vaccine can reduce the risk of your child contracting the highly contagious chickenpox infection.
Older children and adults are at higher risk the later they catch the virus.
Seek help when:
Clubfoot
Clubfoot is a condition where the forefront, the section where foot is joined to the lower leg bone is abnormally twisted associated to the lower leg bone that is pointing inward and downward. This can develop in either one or both feet. This condition is also known as Congenital Talipes Equino Varus.
There are two types of Clubfoot:
Symptoms of clubfoot include:
Coughs & Colds

Croup is a common respiratory tract infection in children between the age of six months and 12 years old. It is an infection that affects the child’s upper airway (larynx, trachea, bronchus).
Croup is caused by respiratory viruses. Viral croup usually resolves within one week.
Symptoms of croup include:
Diarrhoea and Upset Stomach
Though loose stools in children can happen on occasion, diarrhoea, however, is when your child passes unformed and watery stools on a frequent basis. They may have food allergies but most of the time this is caused by an infection or a stomach bug.

Gastroenteritis (upset stomach)
Called gastroenteritis, the most common causes are usually viruses like the rotavirus. In younger children, diarrhoea and vomiting may be more serious, especially babies as they can easily lose too much fluid from their bodies and become severely dehydrated.
Seek help from a paediatrician when:
Hand-Foot-and-Mouth Disease (HFMD)
Hand-foot-and-mouth (HFMD) is a common infectious disease that is seen in children and infants. The disease is usually mild and self-limiting.
HFMD is contagious. The virus spreads from person to person through faecal-oral route and the infected person's nose and throat secretions, fluid from scabs or blisters.
Symptoms of HFMD include:
Seek help from a paediatrician when:
Heat rash
A heat rash appears after exposure to heat or sweat. However, it usually disappears after a cool environment is provided to the affected child, such as wearing loose clothing or switching on air-conditioning.
A heat rash typically does not necessitate treatment. If symptoms worsen, they are usually attributed to other illnesses. Bring your child to a paediatrician if you have concerns about your child’s condition.
Influenza
Influenza or more commonly known as the flu is caused by a virus and spreads through the air when infected people cough/sneeze.
Symptoms of influenza include:
If you notice these symptoms, seek your doctor’s help for medication. Most influenza cases can be well managed at home with medication, rest, and proper fluid intake by the child.
Getting flu vaccines every year can reduce the risk of contracting influenza for various common strains.
Pertussis (Whooping Cough)
Pertussis or whooping cough is an acute bacterial infection caused by the bacteria Bordetella pertussis. This infection affects the respiratory tract and is highly contagious. It spreads through respiratory droplets and by direct contact with fluids from the nose or mouth of infected person.
Serious cases and fatalities are often observed in early infancy stage.
Symptoms of pertussis include:
Ensure that your infant receives the pertussis vaccination at 2, 3 and 5 months of age according to the Malaysian National Immunisation Programme.
Pneumonia
Pneumonia is an infection that affects one or both lungs. It can usually be triggered by cold or flu bouts.
Pneumonia causes fluid or pus to fill the air sacs of the lungs. It obstructs the normal exchange of gas inside the lungs, which leads to low levels of the oxygen in the blood and impaired removal of carbon dioxide from the body.
Young children are considered most susceptible to pneumonia.
Symptoms associated with pneumonia differ considerably depending on the cause and the health condition of the child. They may include:
Sinusitis
The build-up of sinus fluids allows viruses and bacteria to grow which may cause a sinus infection.
Symptoms of sinusitis include:
Skin allergy
Skin allergy can be acknowledged if the onset of the rash is after exposure to an allergen, which causes the allergic reaction. The reaction may occur within minutes, or between 4 to 6 hours after the exposure.
Allergens are usually substances or foods that trigger an allergic reaction. Common culprits of an allergic reaction in children are certain foods such as eggs, seafood, and peanuts.
Symptoms of an allergic skin reaction include:
Sticky eyes
‘Sticky eyes’ is a common condition in newborn babies and young children. This condition is due to their tear ducts still developing. Symptom includes sticky discharge in the corner of their eyes or eyelashes.
Strep throat (throat infection)
Strep throat is an infection caused by the bacteria Streptococcus pyogenes.
Symptoms of strep throat include:
Seek help from a paediatrician to run a strep test if your child shows the symptoms above.
Swollen gums
Swollen gums in children are often an indication of gum disease. They may appear red or purplish due to increased blood flow in the affected area and can also seem smooth or shiny. In many cases, swollen gums will bleed easily, especially when brushed.
If your child’s gum swelling does not subside after a few days or if it causes significant discomfort, consult a dentist or periodontist for further assessment and treatment.
Tonsillitis
The tonsils are two lymph nodes that are located on each side of the back of the throat that is associated with the immune system. When there is a threat to the immune system, it releases antibodies to fight bacteria that infects the mouth area. The infected tonsils can suffer from inflammation and become enlarged leading to tonsilitis. Viral infection is the main cause of tonsillitis.
Symptoms of tonsillitis include:
Torticollis (Wry Neck)
Torticollis, also known as wry neck, occurs when the baby's head is tilted – it is where the chin points to one shoulder, while the head tilts towards the opposite shoulder.
Congenital torticollis occurs usually when the neck muscle at the back of the baby's neck (Sternocleidomastoid Muscle) gets shortened. After birth, this condition might appear due to scar tissues and tightness of the muscle only on one side of the neck. This condition may occur later in childhood.
Another factor might be caused by a bone problem in the neck portion of the spine (cervical spine). This is known as a congenital malformation of the cervical spine.
Symptoms of torticollis include:
Urinary Tract Infection (UTI)
Urinary tract infection (UTI) is a common bacterial infection of the bladder or kidneys. It is a common cause of fever in young children. UTI can be suspected especially when no other obvious sources of fever are identified.
Symptoms of UTI in children include:
Take your child to a paediatrician for if he/she shows the symptoms above. UTI in children must be treated because untreated UTI poses a risk of kidney damage.
