Dengue Fever

Dengue fever is a disease caused by a virus carried by mosquitoes. These mosquitoes then transmit the virus to humans.

Symptoms of Dengue fever
Symptoms, which usually begin four to six days after infection and last for up to 10 days, may include:

  • Sudden high fever
  • Severe headache
  • Pain behind the eyes
  • Severe joint and muscle pain
  • Fatigue
  • Nausea
  • Vomiting
  • Skin rash, which appears two to five days after the onset of fever
  • Mild bleeding (such as nose bleed, bleeding gums, or easy bruising)

To protect yourself:

  • Stay away from heavily populated residential areas, if possible.
  • Use mosquito repellents, even indoors.
  • When outdoors, wear long-sleeved shirts and long pants tucked into socks.
  • When indoors, use air conditioning if available.
  • Make sure window and door screens are secure and free of holes. If sleeping areas are not screened or air conditioned, use mosquito nets.
  • If you have symptoms of dengue, speak to your doctor.
  • To reduce the mosquito population, get rid of places where mosquitoes can breed. These include old tires, cans, or flower pots that collect rain. Regularly change the water in outdoor bird baths and pets’ water dishes.
  • If someone in your home gets dengue fever, be especially vigilant about efforts to protect yourself and other family members from mosquitoes. Mosquitoes that bite the infected family member could spread the infection to others in your home.

Symptoms of heat stroke
Body temperature rises above 40°C. But fainting may be the first sign.

  • Throbbing headache
  • Dizziness and light-headedness
  • Lack of sweating despite the heat
  • Red, hot, and dry skin
  • Muscle weakness or cramps
  • Nausea and vomiting
  • Rapid heartbeat, which may be either strong or weak
  • Rapid, shallow breathing
  • Behaviour changes such as confusion, disorientation, or staggering
  • Seizures
  • Unconsciousness


To Protect Yourself
When the heat index is high, it’s best to stay in an air-conditioned environment. If you must go outdoors, you can prevent heat stroke by taking these steps:

  • Wear lightweight, light-coloured, loose-fitting clothing, and a wide-rimmed hat
  • Use a sunscreen with a sun protection factor (SPF) of 30 or more.
  • Drink extra fluids. To prevent dehydration, it’s generally recommended to drink at least eight glasses of water, fruit juice, or vegetable juice per day.
  • Reschedule or cancel outdoor activity. If possible, shift your outdoor times to the coolest times of the day, either early morning or after sunset.

Heat Stroke

Heatstroke is where the body is no longer able to cool itself and his/her body temperature becomes dangerously high

Haze in Malaysia

The dominant factor that contributes to the haze problem is the burning of forests on a large scale. The weather conditions in the tropical rain forests are too hot so can cause plants to burn by itself due to the rising of temperature. This happens because of the phenomenon of the global warming on this earth.

Air Pollution Index (API)
The air quality in Malaysia is reported as the Air Pollution Index (API).

This scale below shows the health classifications used by the Malaysian government.

0-50 Good
51-100 Moderate
101-200 Unhealthy
201-300 Very Unhealthy
301 Hazardous

If the API exceeds 500, a state of emergency is declared in the reporting area.

Action during Haze

  • Reduce outdoor physical activity.
  • Try to stay inside the building or house. If need to be outside, it is advisable to wear a mask.
  • Make sure the air inside the house or building is clean. Avoid sources of indoor pollution such as cigarette smoke.
  • Drink a lot of water.
  • Wash hands and face thoroughly after attending events outside.


Effect of haze to health

  • Cough, Flu
  • Inflammation of lungs.
  • Asthma attacks
  • Sore throat
  • Eye pain
  • Complication of heart
  • Eczema and others.
