Epidemiology Information in Malaysia

Epidemiology: Study of factors of pathogens affect heath and illness of population, when, where and how they are transmitted in a population

Clinical Factors associated with Mycoplasma pneumoniae infection in 170 children admitted with Community Acquired Pneumonia

  • Odd ratio (OR): Odd ratio is a measure of effect size which describes strength of association or non-independence between two binary data values. It is used as descriptive statics and plays an important role in logistic regression.
  • Confident interval (CI): Interval estimate of a population parameter.
  • p-value (p): Probability of observation due to chance.

The lower the p-value, the higher the statistical confident level.

  • Serology positive = found antibody for Mycoplasma pneumoniae in serum of the particular people
  • Serology negative = cannot found antibody for Mycoplasma pneumoniae in serum of the particular people

From the table, we can see that among 31 children among 40 children who are older than 3 years old were tested and were having antibody for Mycoplasma pneumoniae, 61 children among 130 children do not find antibody for Mycoplasma pneumoniae.

28 boys’ and 12 girls’ serum have found having the antibody for Mycoplasma pneumoniae. This means boys have a high chance to be infected by Mycoplasma pneumoniae. Among three races in Malaysia, Chinese has the most higher positive result for serology positive test which means have antibody to Mycoplasma pneumoniae in their blood.

Statistic of Detection of Mycoplasma pneumoniae in adult patients and pediatric patient
  • Pediatric: Medical care of children
  • This statistic shows that Infection of Mycoplasma pneumoniae appear more frequently among children.
  • Among 20 adult patient, there is only a adult infected by Mycoplasma pneumoniae. But, there are 15 children among 20 children affected by Mycoplasma pneumoniae.

World distribution of Pneumonia disease

Around the world, Africa is the largest portion that its resident having Pneumonia.
