Summary of Data: Tables and Equations

With the collected reports on injuries and deaths, the cumulative incidence, case fatality rates and proportionate mortality ratio were computed through the following formula, and the results are as follows:

Cumulative Incidence = [(no. of new cases / population at risk given a period of time)] 

Table 1. Incidence of Deaths and Injuries by Cause in the Philippines: (Aug. 17-30)

	Mortality Rate (per 10,000,000)	Incidence of Deaths by Cause (per 10,000,000)
		Drowning	Electrocution	Collapsed Structures	Swept by Flood	Unknown
# of Cases	27	16	2	2	5	2
CI	87.2	51.7	6.46	6.46	16.1	6.46
	Morbidity Rate due to Injuries  (per 10,000,000)	Incidence of Injuries by Cause
		Drowning	Electrocution	Collapsed Structures	Swept by Flood	Unknown
# of cases	30	0	0	28	0	2
CI	96.9	0	0	90.4	0	6.46
population at risk: 3, 096, 392 *CI: Cumulative Incidence

Table 2. Incidence of Deaths and Injuries by Cause in Region IV- (Aug. 17-30)

	Mortality Rate (per 10,000,000)	Incidence of Deaths by Cause (per 10,000,000)
		Drowning	Electrocution	Collapsed Structures	Swept by Flood	Unknown
# of Cases	12	4	0	2	5	1
CI	300	100	0	50	124	25
	Morbidity Rate (per 10,000,000)	Incidence of Injuries by Cause
		Drowning	Electrocution	Collapsed Structures	Swept by Flood	Unknown
# of cases	2	0	0	2	0	0
CI	50	0	0	50	0	0
population at risk: 400,001 *CI: Cumulative Incidence

Case Fatality Rate = [(no. of deaths specific cause / no. of cases specific cause)] x 100%

Table 3. Case Fatality Rate in the Philippines

	Drowning	Electrocution	Collapsed Structures	Swept by Flood	Unknown
# of Cases	16	2	30	5	4
# of Death	16	2	2	5	2
Case Fatality Rate	100 %	100 %	6.7 %	100 %	50 %

Table 4. Case Fatality Rate in Region IV-A

	Drowning	Electrocution	Collapsed Structures	Swept by Flood	Unknown
# of Cases	4	0	4	5	1
# of Death	4	0	2	5	1
Case Fatality Rate	100 %	0	50 %	5	100 %

Proportionate Mortality Rate = (no. of deaths from a specific cause / no. of total deaths)

Table 5. Proportionate Mortality Ratio in the Philippines

	Deaths due to Specific Causes
*Total Number of Deaths: 27	Drowning	Electrocution	Collapsed Structures	Swept by Flood	Unknown
Number of Deaths	16	2	2	5	2
Case Fatality Rate	59.3 %	7.4 %	7.4 %	18.5 %	7.4 %
