What does the Slide Positivity Rate (SPR) measure in (a) indices?
If a region has 50 deaths due to malaria and 2000 total malaria cases, what is the Case Fatality Rate (CFR)?
A health officer wants to know the percentage of malaria cases that are due to P. falciparum. Which formula should they use?
(Total number of deaths due to malaria / Mid-year population) × 1000
(Number of confirmed P. falciparum malaria cases during one year / Population under surveillance) × 1000
(Total number of deaths due to malaria / Total number of malaria cases) × 100
(Total number of blood smears positive for P. falciparum / Total number of blood smears positive for malaria parasite) × 100
A district examined 10,000 blood slides for malarial parasites in a year, with a population under surveillance of 200,000. What is the Annual Blood Examination Rate (ABER)?
5%
0.5%
20%
50%
Which formula is used to calculate the Microfilarial Rate (MFR)?
(Number of people positive for microfilaria in peripheral blood / Total population examined) × 100
(Number of people with clinical manifestations of filariasis / Total population examined) × 100
(Number of people positive for microfilaria in peripheral blood + Number of people with clinical manifestations) / Total population examined × 100
(Total population examined / Number of people positive for microfilaria in peripheral blood) × 100
What does the Filarial Disease Rate (FDR) measure?
The proportion of people with clinical manifestations of filariasis in a population
The proportion of people positive for microfilaria in peripheral blood
The total number of people examined for filariasis
The sum of people with microfilaria and clinical manifestations
If a population of 1,000 people is examined, and 20 people are positive for microfilaria in peripheral blood, what is the Microfilarial Rate (MFR)?
2%
20%
0.2%
10%
How does the Filarial Endemicity Rate (FER) differ from the Microfilarial Rate (MFR)?
FER includes both people positive for microfilaria and those with clinical manifestations, while MFR includes only those positive for microfilaria
FER only includes people with clinical manifestations, while MFR includes both groups
FER is always lower than MFR
FER is calculated without multiplying by 100
A village has 10 people positive for microfilaria, 15 people with clinical manifestations, and a total population examined of 500. What is the Filarial Endemicity Rate (FER)?
5%
10%
25%
15%
