World Rabies Day: Post-Bite Tests – Why Timing Matters

What Is World Rabies Day?

World Rabies Day is an annual global awareness campaign to raise awareness about rabies prevention and control. Coordinated by the Global Alliance for Rabies Control and endorsed by major health organisations, like the WHO, the day aims to educate people about the impact of rabies, share prevention strategies, and advocate for effective elimination efforts. By connecting organisations and communities, World Rabies Day enhances advocacy, education, and access to resources to combat this deadly but preventable disease.

When Is World Rabies Day 2025?

World Rabies Day 2025 falls on Sunday, September 28th, marking the anniversary of Louis Pasteur's death. Pasteur was the renowned scientist who developed the first rabies vaccine, making this date a fitting tribute to his ground-breaking work in rabies prevention.

Theme for World Rabies Day 2025

The World Rabies Day theme for 2025 is "Act Now: You, Me, Community", emphasising the shared responsibility of individuals, professionals, and communities in preventing rabies transmission.

The theme's key elements include:

• You: Take personal responsibility by vaccinating pets, learning about prevention, and advocating for better policies
• Me: Lead by example through professional education, supporting elimination initiatives, and inspiring others
• Community: Collaborate with your community on mass vaccination campaigns and on education programmes on the history of World Rabies Day.

Why World Rabies Day is Important

World Rabies Day galvanises global action towards the ambitious "Zero by 30" goal – zero human deaths from dog-mediated rabies by 2030.

Its importance lies in:

• Raising awareness of rabies prevention and control in at-risk communities
• Promoting vaccination of pets and animals, a primary prevention strategy
• Encouraging policy change and increased resources for rabies elimination
• Spreading knowledge, empowering individuals and communities to take preventive steps

Rabies – A Deadly Yet Preventable Disease

• Rabies is a viral disease affecting the central nervous system, causing brain inflammation.
• Without timely treatment, it is almost always fatal.
• However, effective vaccines and prompt post-exposure prophylaxis can prevent rabies onset after exposure.

Global Rabies Statistics

• Over 59,000 people die from rabies each year globally, according to WHO estimates.
• More than 99% of human rabies cases result from dog bites, with the majority (over 95%) occurring in Asia and Africa.
• Children under 15 years of age are at the highest risk.

Understanding Rabies Exposure

Rabies exposure occurs when the virus enters the body, typically through a bite or scratch from an infected animal. On World Rabies Day 2025, the focus will be on raising awareness about the critical aspects of exposure and how timely action can save lives.

How Rabies Spreads

• Transmitted mainly through saliva from the bite of an infected animal
• Can also spread via scratches if saliva contacts broken skin or mucous membranes

High-Risk Animals and Situations

• Dogs are the most common source worldwide
• Other risk animals include bats, raccoons, skunks, foxes, and certain livestock
• Extra caution needed if animals show unusual or aggressive behaviour

Symptoms of Rabies in Humans

• Early: fever, headache, weakness
• Progressive: anxiety, confusion, agitation, hallucinations
• Advanced: hydrophobia (fear of water), paralysis, coma, and eventually death

Why Post-Bite Diagnostic Tests are Crucial

Prompt diagnostic testing after a potential rabies exposure is vital because early detection and intervention save lives. The World Rabies Day theme for 2025 urges people to act immediately to prevent rabies complications.

What Are Post-Bite Tests for Rabies?

• Post-bite tests are laboratory analyses used to detect the presence of the rabies virus or the body’s immune response, though these tests are generally more useful for research and epidemiological surveillance than immediate clinical decision-making.
• These may involve PCR tests for rabies or to identify viral genetic material, antibody tests to check for immune reaction, or tissue biopsies for confirmation.

Why Timing Matters in Rabies Diagnosis

• Rabies symptoms often appear after the virus has travelled from the exposure site to the brain, which can take weeks to months.
• Delaying testing or treatment until symptoms appear is almost always fatal, as rabies is rarely survivable once clinical signs develop.

Ideal Timeline for Testing After a Bite

• Immediate wound cleansing and medical evaluation are critical.
• Post-exposure prophylaxis (PEP) should be initiated immediately after a potential rabies exposure; diagnostic tests are rarely required for initial clinical decisions and should never delay PEP.

Immediate Steps to Take After an Animal Bite

If you are bitten or scratched by an animal, acting quickly can make a critical difference in preventing rabies. Before seeking medical care, there are a few immediate steps you should follow to reduce the risk of infection.

Wash the Wound Thoroughly

Clean the bite area with soap and water for at least 15 minutes to help remove the virus from the wound.

Seek Medical Attention Immediately

Medical professionals assess the risk, clean wounds further, and determine the need for vaccination or immunoglobulin.

Get Post-Exposure Prophylaxis (PEP)

Timely administration of rabies vaccine (and, if needed, rabies immunoglobulin) prevents the virus from causing illness.

Common Rabies-Related Tests

When rabies exposure is suspected, doctors may recommend certain tests to confirm the presence of the virus or the body’s response. These common rabies-related tests help guide diagnosis and support timely treatment decisions.

Blood Antibody Test

• Detects antibodies produced by the body against the rabies virus
• Antibodies usually appear late in the infection
• More useful for surveillance and research than for early diagnosis

Skin Biopsy or Saliva Test

• Involves testing skin or saliva samples for rabies virus markers
• Uses molecular or immunohistochemical techniques to detect viral RNA or antigens
• Provides supportive evidence but may not always confirm infection alone

PCR Test for Rabies

• Uses polymerase chain reaction (PCR) to detect rabies virus genetic material
• Can be performed on saliva, cerebrospinal fluid, or tissue samples
• Offers early, sensitive, and specific diagnosis if the test is positive

How Labs Play a Role in Rabies Prevention

Laboratories are essential in rabies prevention, as they provide accurate testing, confirm diagnoses, and guide timely treatment and public health action.

Early Detection Saves Lives

Quick confirmation of rabies in animals or humans enables immediate public health action, including contact tracing and targeted PEP.

Public Health Campaigns

Labs support surveillance, monitor the effectiveness of control measures, and contribute to educational campaigns by sharing accurate data.

Preventive Measures to Avoid Rabies

Taking preventive measures is the most effective way to protect yourself and your community from rabies, reducing the risk of exposure before it happens.

Vaccinate Pets Regularly

Keeping dogs, cats, and ferrets up to date with rabies vaccination breaks the cycle of transmission.

Avoid Contact with Stray Animals

Refrain from approaching or handling unknown or wild animals, especially if they appear sick or unusual.

Community Vaccination Drives

Organised mass vaccination of animals lowers rabies risk in human populations and helps achieve elimination targets.

FAQs

What is the theme of Rabies Day 2025?

World Rabies Day's theme for 2025 is "Act Now: You, Me, Community", focusing on shared responsibility and action against rabies.

Why is September 28th World Rabies Day?

September 28th marks the anniversary of Louis Pasteur's death, the scientist who developed the first rabies vaccine.

How soon should I get tested after a suspected rabies bite?

Diagnostic testing is rarely necessary immediately after a bite. Immediate wound cleansing, medical assessment, and starting post-exposure prophylaxis (PEP) are the critical steps; PEP should never be delayed for test results.

Can rabies be detected through blood tests?

Rabies antibodies are detectable by blood tests but usually only after the infection has progressed, so blood tests are not suitable for early diagnosis or for making immediate clinical decisions after exposure.

What is the survival rate if rabies is detected early?

Rabies is almost always fatal once clinical symptoms appear. However, if post-exposure prophylaxis (PEP) is administered promptly after exposure, before symptoms develop, survival is effectively 100%.

Is rabies preventable?

Yes, rabies is 100% preventable through vaccination of pets, avoiding risky animal contact, and timely post-exposure prophylaxis if bitten.
