Epidemiological Characteristics of Human Rabies - Shandong Province, China, 2010-2020

Introduction: Rabies is a viral zoonotic disease that causes progressive and fatal inflammation in the brain. Rabies has caused more than 5,000 human deaths in Shandong Province since 1955. This study aimed to analyze the epidemiological characteristics of human rabies in Shandong Province from 2010 to 2020 and to provide a scientific basis for policy changes. Methods: The data of reported human rabies cases from 2010 to 2020 were obtained from China's National Notifiable Disease Reporting System, and data related to exposure and post-exposure prophylaxis (PEP) of the cases were acquired through case investigation. Results: A total of 414 human rabies cases were reported in Shandong Province from 2010 to 2020. Out of the 414 total cases, 87.20% were primarily farmers; 83.10% were over 40 years old. 70.29% (265/377) belonged to category. exposure; and 96.67% (377/390) were exposed to the virus through infected dogs. The vaccine inoculation rate of these cases after exposure was only 8.85%; 1.03% (4/390) had been vaccinated with rabies immunoglobulin, developing the disease 11 to 13 days after category. exposure. Conclusions: Dogs were still the primary animal hosts. Most rabies patients died due to no or inadequate post-exposure prophylaxis. Vaccine inoculation rates for dogs should reach the target of 70% as soon as possible. Health departments should improve the accessibility and quality of PEP; and improve the health literacy of the elderly in rural areas.

Automated summary

This study analyzed the epidemiological characteristics of human rabies in Shandong Province from 2010 to 2020. The results showed that dogs were still the primary animal hosts, and most rabies patients died due to no or inadequate post-exposure prophylaxis. The study suggests that the vaccination rate for dogs should be increased, and accessibility and quality of post-exposure prophylaxis should be improved. Additionally, health literacy of the elderly in rural areas should be enhanced.
