Abstract :
Objectives: (1) To determine the profile of reported infectious diseases. (2) To analyze the reported infectious
diseases with reference to certain factors. (3) To evaluate the functionality of the notification system.
Methodology: The hospital record-based study was carried out at a tertiary care hospital in Goa. The
“Malaria, Dengue, Encephalitis Notification Reports” for a period of 18 months (Jan 2016–Jun 2017) were
scrutinized.
Data was entered in excel and analyzed in SPSS version 22.
Results: A total of 2360 cases were recorded as per reports. 2043 (86.5%) of these were cases of malaria,
225 (9.6%) dengue, 55 (2.3%) encephalitis, 37 (1.6%) leptospirosis, and zero cases of chikungunya. Among
the malaria cases, majority of the cases notified were plasmodium vivax-type. There were a total of 30
deaths reported, majority being due to leptospirosis 7 (23%) and encephalitis 7 (23%). The highest case
fatality rate of 22 was due to cerebral malaria.
Only 48 out of 346 (14%) of the reports were duly complete. Incorrect notification was seen in 2% of the
reports. Many a times (25%), the reports were not sent on a daily basis.
Conclusion: The hospital-based surveillance is an effective notification system for cases reporting to the
hospitals. It is a cost-effective method of surveillance. If the problems of inconsistency, incompleteness,
untimely reporting, etc., are solved, it has potential to revolutionize by timely detection and control
measures on impending disease outbreaks
