In short
Wash the wound with soap under running water for about fifteen minutes, then go for the vaccine today. Rabies is almost always fatal once symptoms begin, and preventable by treatment started before they do. No test can tell you in advance whether you are infected, and a bite from weeks ago still counts.
Emergency if: Wash the wound for fifteen minutes, then go straight to an emergency department tonight - not to tomorrow's clinic - for multiple bites, deep wounds, or any bite to the head, face, neck, genitals or hands including the fingers - WHO's regional guidance lists these richly innervated sites as high risk and they carry the shortest incubation periods. Any bat contact - a bite, a scratch, saliva on a mucous membrane, or waking to find a bat in the room, since bat bites can be tiny and may leave no mark - is treated as category III and started immediately. A bite in a child under about 14, or in anyone with severely suppressed immunity, belongs here too - WHO's regional decision tree starts treatment immediately in both, rather than waiting on any investigation of the animal. And if someone bitten weeks or months ago develops tingling, pain or burning at the old bite site, fever, anxiety, confusion, difficulty swallowing or fear of water, that is an emergency admission: those are the first clinical signs, and treatment must never be delayed to see whether they appear.

What do I do in the first fifteen minutes?
Wash the wound. WHO's advice is extensive wound washing with water and soap for at least 15 minutes as soon as possible after an exposure, and its guidance for the public puts it more plainly still: wash wounds and scratches immediately with soap or detergent and flush them thoroughly for about 15 minutes with copious amounts of water. If soap is not available, flush with water alone. WHO calls wound washing the most effective first-aid treatment against rabies. Fifteen minutes is far longer than it feels; use a clock or a running tap and count it out rather than estimating.
After the washing and flushing, apply an iodine-containing or antiviral preparation on top of the wound, which WHO's public guidance times at 15 minutes after it has been washed and flushed. National guidance in this region asks for the same sequence: gentle, thorough washing with soap or detergent under running water, then a chemical virucidal agent such as povidone iodine or alcohol. If there is none in the house, do not go out looking for one: washing is the step WHO calls the most effective first aid, and the facility has the rest. Do not touch the wound with a bare hand. Then go to a health facility, today, not at tomorrow's outpatient hour. Washing is the first step of treatment, never a substitute for it.
02
Why does washing matter so much when a vaccine exists?
Because the virus is still at the bite when you are standing at the tap. Rabies enters through a bite or scratch, and national guidance notes it can persist and even multiply at the site of the bite for a long time, which is why removing saliva mechanically and inactivating virus chemically buys real ground before the immune system has any answer. WHO's regional decision tree describes washing the wound with copious water and soap for 15 minutes followed by an antiseptic as a life-saving practice, and singles it out as especially important for people whose immunity is suppressed.
The same guidance makes a point that matters if you are reading this hours or days late: wound toilet must still be performed even if you report late, because as long as there is an unhealed wound it can be washed. The maximum benefit comes from cleaning a fresh wound immediately, but late washing is not pointless and late attendance is not a reason to stay away. Wash now, and go now, in that order, without letting the first delay the second by more than those fifteen minutes.
03
Which animals and which kinds of contact actually carry risk?
Dogs dominate. WHO estimates about 59 000 rabies deaths a year, with 40% in children under 15, and says that in up to 99% of human rabies cases dogs are responsible for transmitting the virus. National guidance in this region treats a bite by any warm-blooded animal as needing post-exposure treatment, and treats every bite by a wild animal, or any animal bite in forest or wild surroundings, as the most severe category. Exposure to domestic rodents, squirrels, hares and rabbits does not ordinarily require it. A provoked bite is still managed as an exposure.
It is not only bites. WHO's categories count licks on broken skin and saliva reaching a mucous membrane, meaning eyes, nose or mouth, as transdermal-level exposure. Bats are their own case. WHO's regional decision tree states that if exposure was to a bat, treatment for category III should be started immediately, and lists bite, scratch or mucous membrane exposure from a bat as high-risk. CDC adds the practical warning that bat bites can be tiny and you may not even know you were bitten, so any bat contact belongs in front of a doctor rather than in your own judgement.
04
Category I, II or III: which one is my bite?
Category I is touching or feeding an animal, a lick on intact skin, or contact of intact skin with secretions. With a reliable history, and only then, it needs no vaccine; if you are not sure the skin was unbroken, it is not category I. Category II is nibbling of uncovered skin, or minor scratches or abrasions without bleeding, and it needs wound management plus the vaccine course. Category III is a single or multiple transdermal bite or scratch, a lick on broken skin, or contamination of a mucous membrane with saliva, and it needs wound management, rabies immunoglobulin and the vaccine. Those are WHO's categories, carried into national guidance unchanged.
The line between II and III is thinner than it sounds, and the rule when you cannot place it is to treat upwards. National guidance says risk assessment can be complex and confusing and that when in doubt treatment should be started. Two adjustments are worth knowing. In someone whose immunity is compromised, immunoglobulin is given for category II as well as III. And WHO's regional guidance flags multiple bites, deep wounds, bites to the head, neck, face, genitals or hands, and any bat exposure as high risk, whatever the wound looks like.
05
What does the treatment involve, and on which days?
A numbered course of injections, starting today. National guidance in this region uses the five-dose intramuscular Essen regimen, one dose each on days 0, 3, 7, 14 and 28, given in the deltoid rather than the buttock, with the antero-lateral thigh for infants and young children. The intradermal alternative, the updated Thai Red Cross schedule, gives two sites per visit on days 0, 3, 7 and 28. CDC's schedule for a previously unvaccinated person is four doses on days 0, 3, 7 and 14, with a fifth on day 28 if immunocompromised, and two doses on days 0 and 3 for someone already vaccinated. Day 0 is the day of your first dose, not of the bite.
For category III, rabies immunoglobulin is added. As much of the calculated amount as is anatomically feasible is infiltrated into and around the wounds to neutralise virus sitting there, and any remainder goes deep intramuscularly at a site distant from the vaccine injection. It is given once, preferably within 24 hours of exposure alongside the first vaccine dose. If missed then, it can still be given up to the seventh day after that first dose; beyond it, it is not indicated, because your own antibody response has begun and late immunoglobulin can suppress it. The amount is the dose your doctor sets for your weight.
06
The dog is ours and it is vaccinated. Can we wait and watch it?
No - and that is WHO's own answer, not ours. It changes what happens on day 10, not what happens today. WHO's guidance for the public asks directly whether simply observing the biting animal for 10 days without starting treatment is justified, and answers no: where rabies is prevalent, treatment for the exposed person is started promptly and the animal is observed alongside it. The 10-day window exists because an animal infected with rabies will usually show clinical signs, or die, within one to seven days. National guidance in this region applies that window to dogs and cats only, because the natural history of rabies in other mammals is not fully understood, and WHO's regional decision tree takes the same view and asks for a longer, more conservative clinical investigation for other species.
If the animal is still healthy at the end of those 10 days, the course can be converted. Under the Essen schedule that means skipping the day 14 dose and giving it on day 28, turning treatment into pre-exposure protection; with the intradermal schedule the full course is completed regardless. A vaccination card on the animal is reassuring but not proof: vaccine failure happens through poor administration, poor vaccine quality, poor animal health, and because one dose does not always give lasting protection. WHO says treatment may be unnecessary only where all three hold together - the animal is healthy and normal, the bite was provoked, and its up-to-date high-quality vaccination is properly documented - and that is a judgement for the doctor who examines you, made after you have been seen. It is not one to make at home with the card in your hand. Wash, take the card with you, and go today.
07
Is there a test that can tell me whether I caught it?
No, and this is the single most important thing to understand. WHO states that there are currently no WHO-approved diagnostic tools for detecting rabies infection before the onset of clinical disease. There is no blood test, no swab and no scan that can look at you a week after a bite and tell you whether virus is travelling up a nerve. The decision to treat is made entirely from the exposure: which animal, what contact, which category, which body site. That is why the assessment is a conversation with a doctor and not a laboratory request.
The reason nobody waits is the other end of the illness. WHO states that once the virus infects the central nervous system and clinical symptoms appear, rabies is fatal in 100% of cases, and that there is currently no effective treatment for rabies after clinical signs appear. The incubation period is typically two to three months but can range from one week to one year, and head and neck wounds, and wounds in richly innervated areas such as fingers, generally have shorter incubation because the inoculation sits close to nerves. That is a reason for urgency rather than for despair: WHO states in the same breath that rabies deaths are preventable with prompt post-exposure treatment, which works by stopping the virus from reaching the central nervous system. Wound washing, the vaccine course and, where indicated, immunoglobulin, all given before symptoms appear, are what prevent every part of this.
08
What do people get wrong?
Four things, and each of them costs time or does damage. First, putting something on the wound. Nothing goes on it but water, soap and, after the washing, the iodine preparation: no chilli powder, no plant juice or herb, no oil, turmeric, lime, salt, soil, chalk or betel leaf, no acid or alkali. WHO tells people to avoid applying such irritants, and national guidance in this region names that same list as unnecessary and damaging. If something has already been applied, do not scrub at it - wash gently with soap or detergent to remove it, flush immediately with copious water, and tell the doctor what was used. Second, covering it: WHO's public guidance says not to cover the wound with dressings or bandages. Do not burn or cauterise it either, since cauterising is no longer recommended and offers no advantage over washing.
Third, stitching. National guidance says suturing should be avoided as far as possible; if it is surgically unavoidable, immunoglobulin is infiltrated first and suturing is delayed by a few hours so antibody can diffuse into the tissue, with minimum loose sutures used only to arrest bleeding in a life-threatening situation. Fourth, waiting to see whether the animal dies, or whether the wound looks infected, or whether symptoms appear. None of those are decision points. Someone presenting months or even years after a possible exposure should still be evaluated and treated as though the event had just happened.
After an animal bite: who needs what, and how fast
Routine — see a doctor
Only category I contact needs no vaccine - you touched or fed an animal, or it licked skin that was completely unbroken - and only where the history is reliable and you are certain the skin was intact. If you cannot be certain, it is not category I: treat it as category II and be seen today. Two other routine but non-optional things: go back for every remaining dose on its numbered day even if you feel well, even if the animal is alive and even if the wound has healed, and keep the vaccination card so that a future bite can be given the shorter schedule. Pregnancy, breastfeeding, infancy, old age and other illness are not reasons to skip or delay the course.
Same-day — call promptly
Every category II and category III exposure needs wound washing and the first vaccine dose today, at an anti-rabies clinic or emergency department - not at tomorrow's outpatient appointment. That means any transdermal bite or scratch, any scratch or abrasion that broke the skin or bled, nibbling of uncovered skin, a lick on broken skin, or saliva in your eyes, nose or mouth. A bite by any wild animal, or any animal bite in forest or wild surroundings, is treated as category III. So is a bite from an animal you cannot identify or find. Take the animal's vaccination record with you if there is one, and tell the doctor exactly where on the body the contact was. A bite from days, weeks or months ago that was never treated belongs here too, today: reporting late is not a reason to stay away, and an unhealed wound can still be washed. Being pregnant or breastfeeding is not a reason to wait, and neither is the animal still looking well.
Emergency — act now
Wash the wound for fifteen minutes, then go straight to an emergency department tonight - not to tomorrow's clinic - for multiple bites, deep wounds, or any bite to the head, face, neck, genitals or hands including the fingers - WHO's regional guidance lists these richly innervated sites as high risk and they carry the shortest incubation periods. Any bat contact - a bite, a scratch, saliva on a mucous membrane, or waking to find a bat in the room, since bat bites can be tiny and may leave no mark - is treated as category III and started immediately. A bite in a child under about 14, or in anyone with severely suppressed immunity, belongs here too - WHO's regional decision tree starts treatment immediately in both, rather than waiting on any investigation of the animal. And if someone bitten weeks or months ago develops tingling, pain or burning at the old bite site, fever, anxiety, confusion, difficulty swallowing or fear of water, that is an emergency admission: those are the first clinical signs, and treatment must never be delayed to see whether they appear.
