Get vaccinated against pneumonia

PREVENTIVE MEASURE: Dr Leong Hoe Nam vaccinating patient Ms Teo Guat Kim against pneumonia.

She had a tummy ache and a persistent fever.

The usually active housewife just did not feel good.

She told The New Paper on Sunday: "I just couldn't get well."

Family members took Madam Teo Guat Kim, 54, to the accident and emergency department of Mount Alvernia Hospital in April.

At the hospital, doctors diagnosed that Madam Teo suffered from "an unusual abdominal infection and underwent emergency surgery".

She later learnt that she had a pelvic infection caused by a germ called Group A Streptococcus.

"Dr Leong Hoe Nam told me it was a life-threatening infection," she said.

It turned out the former tailor developed pneumonia as a result of the infection.

She spent two weeks in hospital, and it took another two months for her to fully recover.

According to the Ministry of Health (MOH), pneumonia is one of the top killers, second only to cancer, in Singapore.

Last year, it remained the number one killer for those aged 70 and older.

According to MOH, pneumonia caused nearly one in five deaths in Singapore in 2014.

Hospitalisation records indicate that pneumonia remains the fifth most common cause, with more than 13,000 admitted for that in 2013.

The lung infection is caused by either a virus or bacteria.

Those most susceptible to the infection include adults above 65 years, children under two, and those with medical conditions such as diabetes and chronic heart or lung disease.


A global study, published in The Lancet medical journal this year, found that between 1990 and 2014, pneumonia deaths in Singapore increased by more than half.

In the first 32 weeks of this year, there were already 87 cases of invasive pneumococcal disease recorded. This is a 17.6 per cent increase from the 74 cases in the same period last year.

Some doctors have urged that the elderly, young children and those who have compromised immune systems get vaccinated against pneumococcal disease, one of the major cause of pneumonia in Singapore.

Dr Wong Hang Siang, a respiratory and critical care medicine physician from Changi General Hospital, said: "Every infection is a cause of concern as this disease causes high mortality even with antibiotics treatment.

"Vaccination is therefore important as a preventive measure."

There are currently two types of pneumococcal vaccines in the market.

Infectious disease physician Leong Hoe Nam said a new one, called the pneumococcal conjugate vaccine, has recently been proven to be effective in preventing pneumonia in the elderly.

"It targets the most common 13 strains of the germ Streptococcus pneumoniae. With this vaccine, we can reduce pneumonia incidence in the elderly by about half," he said.

Respiratory medicine physician Dipika Agrawal of Ng Teng Fong General Hospital said the overall mortality of pneumococcal pneumonia today is between 11 and 20 per cent.

"It can cause respiratory and cardiac complications in some patients and they may require (intensive care) support and artificial ventilation to support the breathing," she said.

"Mortality is also higher in persons over 65 years of age and with existing diseases."

One reason is that their body's protective mechanisms have weakened and they face trouble expelling germs or clearing phlegm from their throats, causing fluids or secretions to enter their lungs.
