As Telangana experienced a double-fold rise in rainfall this year in contrast to the regular pattern, the climatic fluctuations have increased the epidemic potential of Dengue.

Aims and Objectives

The study's primary goals are to examine the frequency of Dengue outbreaks and perform an examination of Dengue to monitor the disease's development. The study highlights the value of epidemiological surveillance to monitor the No. of incidences, evaluate the most prevalent clinical features, and determine how abnormalities in laboratory results help in figuring out the expansion of disease as the seasonal outbreak of endemic Dengue is observed.


In 6-month surveillance research in a tertiary care hospital, data on 100 Dengue cases were gathered and evaluated


Among 100 cases, 44 were women and 56 were men. Ages 21 to 40 were the most impacted (35%). NS1Ag was identified in 85 individuals, whereas Ig M was detected in 10 cases (or 10%). Only 5 patients (5%), a combination of NS1Ag and Ig M positive, were involved. Within one to five days of fever onset, 69 people were hospitalized. Leucopenia was observed in 31 individuals (31%) and was more prevalent in ladies than gents (54.8% vs. 45.2%). The majority of observed clinical features (82%) involved thrombocytopenia. Females had a higher rate than men (56.1% vs. 43.9%). 9 individuals had hypoalbuminemia, while 7 patients had elevated A: G.


In this surveillance study, we conclude that the clinical examination of DF patients demonstrated the efficacy of surveillance systems in assisting and assessing the intensity of the infection.
