Dengue Diseases Dataset

This dataset contains clinical blood parameters used for the detection of dengue disease. It includes key hematological features commonly analyzed in…

Among dengue-positive patients, 38.7% — that's 249 out of 644 patients — have critically low platelet counts below 50,000. This is a significant finding, as low platelet counts (thrombocytopenia) are a hallmark complication of dengue fever and can indicate severe disease risk.

Dengue-positive patients have significantly lower average platelet counts (71,854) compared to dengue-negative patients (193,403). This is a key clinical indicator, as dengue fever is well-known to cause thrombocytopenia (low platelet count). A bar chart has been generated to visually compare these two groups.

The analysis successfully produced a grouped bar chart and data table showing how dengue prevalence differs across gender within pediatric, adult, and elderly age groups. The visualization clearly compares male and female dengue prevalence percentages side by side for each age group.

Among patients with abnormal RBC count or differential count flags, 105 out of 118 patients tested dengue positive — a striking 89.0% positive rate. The bar chart breaks this down further by flag combinations, revealing that patients with BOTH flags abnormal had a 100% dengue positive rate.

The platelet count threshold of 140,000 best separates dengue-positive from dengue-negative patients. Patients with a platelet count at or below 140,000 are predicted as dengue-positive, achieving an overall accuracy of 89.7%. A chart was generated showing how accuracy, sensitivity, and specificity change across different threshold values, with the optimal point clearly marked.

Dengue-positive patients have a notably lower Platelet Distribution Width (PDW) compared to dengue-negative patients. The average PDW for dengue-positive patients is 19.84, while dengue-negative patients have a higher average of 28.52 — a difference of 8.67 units. Two visualizations were generated: a box plot and an overlaid histogram, both clearly showing this separation between the two groups.

Dengue-positive patients have significantly lower average WBC counts compared to dengue-negative patients. The bar chart clearly shows this difference: dengue-negative patients average 6,754 WBC count, while dengue-positive patients average only 3,048 — a difference of 3,706 units.

The analysis produced a chart and data tables showing dengue positive rates across different age groups. The bar chart displays the positive rate (%) for each age group alongside the total number of cases (shown as a line), making it easy to compare both infection burden and risk level at a glance.

No, there is no statistically significant difference in hemoglobin levels between dengue-positive and dengue-negative patients. Both groups show nearly identical average hemoglobin levels, and statistical tests confirm this difference is not meaningful. Two visualizations were generated — a box plot and a histogram overlay — clearly showing the distribution of hemoglobin levels across both groups.

Among 345 dengue-negative patients, 58 (about 17%) have dangerously low platelet counts below 150,000, which warrants further medical investigation. A bar chart has been generated showing the distribution of these patients across three severity ranges.

No, pediatric dengue patients do not show lower platelet counts than adult dengue patients. In fact, the data shows the opposite — pediatric patients have a slightly higher mean platelet count (73,340) compared to adults (71,689). A box plot and summary tables were generated to visualize this comparison.

A large majority — 83.7% — of dengue cases have both abnormal differential count and abnormal RBC count flags. Specifically, 539 out of 644 total dengue cases show both of these abnormal indicators simultaneously.

Among 620 dengue-positive patients, there is a weak positive correlation (r = 0.228) between platelet count and platelet distribution width (PDW). This means that as platelet count increases, PDW tends to slightly increase as well, but the relationship is not strong enough to be considered clinically significant on its own. A scatter plot with a trend line has been generated to visually illustrate this relationship.

Among patients aged 60 and above, dengue prevalence is 53.8% — meaning 105 out of 195 elderly patients tested positive for dengue. The average platelet count across all elderly patients is 124,350.

Yes, there are notable gender-based differences in hemoglobin levels among dengue patients, but not in platelet counts. Males had significantly higher hemoglobin (13.91 g/dL) compared to females (13.45 g/dL), a statistically significant difference (p=0.0001). Platelet counts, however, showed no significant gender difference (p=0.084), though males had slightly lower platelets on average. Two box plot visualizations and supporting data tables were generated to illustrate these distributions.

Using the combined criteria of WBC below 4,000 and platelets below 100,000, 72.5% of dengue cases would be correctly flagged . Out of 644 total dengue cases, 467 would be identified, while 177 would be missed. A donut chart visualizes this breakdown clearly.

The analysis examined how combinations of low platelets (below 93,000), low WBC (below 3,200), and high hemoglobin (above 13.7 g/dL) predict dengue. A data table was generated ranking all 8 possible combinations by their dengue positive rate, showing which combination of lab values is the strongest predictor of dengue.
