Take a look at the essential events, concepts, terms, quotes, or phenomena every day and brush up your knowledge. Here’s your UPSC Current Affairs knowledge nugget for today on notifiable disease and rabies.

(Relevance: UPSC has consistently included questions on health and diseases in its examinations over the years. For instance, in 2014, a question about the Ebola virus appeared in the Prelims, and in 2017, a question about the Zika virus was featured. Therefore, it is crucial to stay updated on diseases that are currently in the news.)

In a significant move to strengthen disease surveillance and ensure timely reporting and treatment, the Delhi government is set to declare human rabies a notifiable disease under the Epidemic Diseases Act, officials said on Sunday. In this context, it becomes important to know about rabies and notifiable disease.

1. Officials said declaring human rabies a notifiable disease is a key component of the plan to achieve zero human deaths from dog-mediated rabies.

2. The move, officials said, would help authorities track disease trends, improve coordination between human and animal health systems, and enable targeted interventions in high-risk areas.

3. The Epidemic Diseases Act, 1897, provides the framework, with the Integrated Disease Surveillance Programme (IDSP) managing data collection and response, enabling early intervention and resource allocation. So far, 20 states have declared human rabies a notifiable disease, as per the official website of the Ministry of Health & Family Welfare’s National Rabies Control Program.

4. In Delhi, once the notification is issued in this regard, all government and private healthcare facilities, including medical colleges and individual practitioners, will be required to report suspected, probable and confirmed cases of human rabies to the designated health authorities. The notification will come into effect immediately after issuance and remain applicable until further orders.

1. A notifiable disease in India is any disease, often infectious like dengue, tuberculosis, or COVID-19, that healthcare providers are legally required to report to public health authorities for monitoring, outbreak prevention, and control.

2. Usually, infections that are likely to cause an outbreak, lead to deaths, and those that need to be investigated quickly to take appropriate public health measures, are declared as notifiable diseases.

3. While the list of notifiable diseases differs from state to state — state governments are  responsible for bringing out the notification.

1. The rabies virus — transmitted through the saliva of infected animals — enters the peripheral nervous system and migrates to the central nervous system (spinal cord and brain).

2. The infected person exhibits behavioural changes and clinical signs when the virus reaches the brain. Clinical signs typically appear three months after a person has been infected. In exceptional cases, clinical signs can develop after a few days, or after more than six months, following an exposure.

3. It leads to a plethora of symptoms, ranging from common ones such as fever, headache, nausea, vomitting to typical ones such as excessive salivation, fear of drinking water, hallucinations and partial paralysis.

4. While it is almost always fatal after one develops the symptoms, it can be prevented by a post-exposure vaccination. This is the reason people need to take rabies shots when they are bitten, scratched, or salivated on open wounds by animals such as dogs, cats, monkeys, and bats.

1. The colonial government introduced the Act to tackle the epidemic of bubonic plague that had spread in the erstwhile Bombay Presidency in the 1890s. Using powers conferred by the Act, colonies authorities would search suspected plague cases in homes and among passengers, with forcible segregations, evacuations, and demolitions of infected places.

2. The Act, which consists of four sections, aims to provide “for the better prevention of the spread of Dangerous Epidemic Diseases.”

3. Notably, the World Health Organization defines epidemics as “the occurrence in a community or region of cases of an illness, specific health-related behaviour, or other health-related events clearly in excess of normal expectancy. The community or region and the period in which the cases occur are specified precisely. The number of cases indicating the presence of an epidemic varies according to the agent, size, and type of population exposed, previous experience or lack of exposure to the disease, and time and place of occurrence.” Epidemics are characterised by the rapid spread of the specific disease across a large number of people within a short period of time.

With reference to notifiable diseases in India, consider the following statements: 1. Notifiable diseases are those which healthcare providers are legally required to report to public health authorities.

2. The primary objective of notifying such diseases is outbreak prevention and control.

Which of the statements given above is/are correct?
