How dangerous is pneumonia?


When people think of pneumonia, they tend to equate it with the elderly and those with weaker immune systems.


But can pneumonia equally affect the young and relatively healthy?


Sungai Buloh Hospital Infectious Disease head Datuk Dr Christopher Lee said that the organisms that cause pneumonia can be transmitted from person to person.


“The bugs that cause infection can spread. They are, in general, contagious, but some types are more contagious than others,” he said.


RSV causes the same symptoms as a cold. It is common, contagious and most children would have had it by age two.


Although RSV infection is usually not a matter for serious concern, it can lead to pneumonia.


Meanwhile, SARS is a serious form of pneumonia.


Identified in 2003, the epidemic was believed to have started when the virus spread from small mammals to humans in China.


SARS is caused by a member of the coronavirus family of viruses – the same family that causes the common cold.


It can spread through coughs, sneezes and infected surfaces.


The infection causes severe breathing difficulty, and sometimes, death.


Symptoms are influenza-like and include fever, malaise, muscle pain (myalgia), headache, diarrhoea and shivering (rigors).


Severe cases often evolve rapidly, progressing to respiratory distress and requiring intensive care.


MERS, a viral respiratory illness, was first reported in Saudi Arabia in 2012 and has since spread to several other countries.


Most people infected with MERS-CoV develop severe acute respiratory illness, including fever, cough and shortness of breath, and many have died from the infection.


Dr Lee said that besides pneumonia caused by viruses, bacterial pneumonia can also be transmitted from one person to another, although they are less contagious than those caused by viruses.


He said that pneumonia is the most frequent infection requiring hospitalisation in most developed and developing countries.


“There’s also significant mortality and morbidity, as well as increase in use of healthcare services,” he said.


According to Dr Lee, the presence of other medical conditions, such as HIV infection, diabetes, the long-term use of steroids and chronic lung diseases like asthma, chronic obstructive pulmonary disease and lung fibrosis, will also determine how easily a person can catch pneumonia, as well as how severe the pneumonia will be.


Pneumonia is also more common among those above age 65, especially if they already have significant co-morbid conditions such as heart disease, chronic lung illnesses, diabetes, renal failure or HIV, he added.


That is why it is important for those in the risk group, as well as everyone else, to adopt preventive measures against bacteria and viruses, Dr Lee said.


These measures include getting the appropriate vaccinations for infections caused by influenza and pneumococcus, adopting good personal hygiene and practising social distancing from those with respiratory infections.


If that is not possible, people should use the appropriate personal protective equipment and practise good hand hygiene, he said.


On whether there is any particular type of pneumonia linked to floods, Dr Lee said “not directly”.


“Flood-related infections tend to be food and water-borne infections, as well as those linked to rodents,” he said.

    About time for Filipinos to learn good hygiene esp on hands. Washing with soap and water after going to toilet is a must. Cover mouth when sneezing or coughing. Be selfish, don’t share your bacteria.

    As always, the best defense against pathogens is a healthy body. Eat right and exercise are the basic steps to take.

    kaya nga dapat yung perang pinambili ng dengue vaccine inilaan n lang sa PCV vaccine dahil sobrang mahal ng PCV vaccine sa mga private pedia at hindi naman sila available sa mga health center. Ayon sa statistics, mas maraming bata ang namatay dahil sa pneumonia kaysa sa kagat ng lamok.

    Is pneumonia the same as Hika? or parehas din ba yan TB.

      Ang hika ay parang nahihirapan huminga, ang TB ay may plema na kulay dugo.
      Ganoon lang yon.

    Actually, yan mga sakit sa baga, iisa lang yan gaya ng pneumonia, Ubo, Sipon, Hika,TB, COPD, Asthma, Pneumothorax, bronchitis, lung cancer.

    They call them with different names, so different kind of medicines and different pharmaceutical companies that will sell.
