Pink eye (conjunctivitis) letters to parents
Pink eye is the condition where the gap between current guidance and district practice is widest, and where the pressure to exclude comes from other parents rather than from the evidence. This page covers the clinical letters and the political one — the reply to a parent demanding that somebody else's child be sent home.
| Cause | Discharge | Itch | Pattern | Usual exclusion implication | Refer today if |
|---|---|---|---|---|---|
| Viral | Watery | Mild | Often one eye then the other; may follow a cold | No exclusion under current guidance | Pain, light sensitivity, vision change |
| Bacterial | Thicker, may crust lids | Mild | Often both eyes; lids stuck in the morning | District policy varies | Marked swelling, fever, pain |
| Allergic | Watery, stringy | Prominent | Both eyes, seasonal, often with sneezing | Not infectious — no exclusion | Not improving with usual measures |
| Irritant or chemical | Watery | Variable | Sudden, follows an exposure | Not infectious — no exclusion | Any chemical splash — irrigate and refer |
| Something else entirely | Variable | Variable | Pain out of proportion, vision affected, eye trauma | Not the question | Always — this is not conjunctivitis triage |
A triage aid, not a diagnosis. Viral and bacterial conjunctivitis overlap enough that clinicians with a slit lamp disagree about them, so a school health office cannot reliably tell them apart and should not claim to. The row that matters most is the last one: pain, light sensitivity, changed vision or any trauma is a same-day referral regardless of what the eye looks like.
Current guidance, and why your letter probably contradicts it
The direction of professional guidance over the last two decades has been away from excluding children for conjunctivitis and away from requiring antibiotic drops before return. The reasoning is straightforward: most cases are viral, so antibiotic drops do nothing for them; bacterial conjunctivitis is usually self-limiting; and by the time an eye is visibly red, exposure has already happened. The exclusion costs school days and the drops cost a provider visit, and neither buys much.
Against that, a district letter written in 2004 and photocopied ever since. The tell is a sentence requiring 24 hours of antibiotic drops before return — a requirement that obliges every family to obtain a prescription for a condition that mostly does not need one.
What a defensible current position looks like:
- No routine exclusion for a child with a red eye who is otherwise well.
- Send home for fever, pain, light sensitivity, vision change, marked swelling, or a child too unwell to take part — which are referral criteria, not conjunctivitis criteria.
- No requirement for a provider note or for drops as a condition of return.
- Hand hygiene and no sharing of towels or pillows, which is the actual control.
- Notify the class only for a cluster, and then mostly to explain why nobody is being excluded.
If your board policy still requires exclusion, apply it and raise the change separately. The pattern is the same as with no-nit policies: the evidence argument is for the board, the letter is for families.
The ten letters
1. Individual family notice. [STUDENT FIRST NAME] came to the health office today with a red, watery eye. I am letting you know so you can keep an eye on it. Pink eye is very common and most cases clear up on their own within a week or two. [STUDENT FIRST NAME] does not need to stay home for it and can be at school as long as they feel well. Please call your provider if there is eye pain, if bright light is uncomfortable, if vision changes, or if it is not improving.
2. Classroom notice. Only for a cluster. The main content should be handwashing and not sharing towels, and one sentence explaining why no child is being excluded.
3. Cluster notice with a wider ask. Adds the request that families tell the health office, which is how you find out whether you have an adenovirus outbreak or three unrelated red eyes.
4. Sent-home letter. For the child who genuinely needed to go — fever, pain, or too unwell. Be explicit that they were sent home for those reasons and not for the red eye itself, because the family will otherwise repeat "sent home for pink eye" to everyone.
5. Explainer for a family expecting exclusion. Warm and specific. I know you may be used to children being kept home for this. Our policy follows current guidance, which is that a child with a red eye who feels well can be at school. Here is why...
6. Reply to a parent demanding another child be excluded. Covered below.
7. Return-to-school clearance. For districts that still require one.
8. Pre-K version. Childcare licensing rules may require exclusion where the school does not. Say which applies to which room.
9. Staff notice. Same rules for adults, plus the point about contact lenses — a staff member with conjunctivitis should not be wearing them.
10. Suspected adenovirus outbreak. Adenoviral conjunctivitis is more transmissible and more persistent than the ordinary case, and a genuine outbreak may warrant health-department contact and a different tone. Reserve this variant for a real cluster, not for three cases in a week.
The letter to a parent demanding another child be excluded
This is the hardest correspondence in the set, because the parent is being reasonable by their own lights and the answer is no.
Dear [PARENT NAME],
Thank you for calling about this. I want to explain our position properly rather than give you a one-line answer.
[DISTRICT] does not exclude students from school for conjunctivitis unless they are unwell — with a fever, eye pain, or symptoms that mean they cannot take part in the day. That follows current guidance from paediatric and school-health bodies. The reasoning is that most cases are viral, so antibiotic drops do not help them; that by the time an eye is visibly red, any exposure in the classroom has already happened; and that excluding a well child costs days of school for very little benefit.
I am not able to discuss another student with you, in the same way I would not discuss your child with another family.
What I can tell you is what protects your child: handwashing, not sharing towels or pillows, and not touching the eyes. If [YOUR CHILD] develops a red eye with pain, light sensitivity or changed vision, call your provider the same day — those are the symptoms that matter.
If you would like to discuss the policy itself, I am happy to talk, and the policy is set by [BOARD/DISTRICT] rather than by the health office.
[NAME], RN — [PHONE]
Three things that letter does. It gives a real reason rather than citing authority. It declines to discuss another child without making that sound like an accusation. And it routes the policy argument to where the policy actually lives, which prevents the nurse from becoming the person a parent argues with about a board decision.
Short forms and sending
SMS to a family. [SCHOOL] health office: [STUDENT] has a red, watery eye. No need to stay home if they feel well. Call your provider for eye pain, light sensitivity or vision change. Questions: [PHONE].
60-second voice, class cluster. This is [NAME], the school nurse at [SCHOOL]. We have seen several cases of pink eye in your child's class this week, so I am calling to explain what we are doing and why. Most pink eye is caused by a virus, which means antibiotic drops do not help, and most cases clear up on their own. We are not sending children home for a red eye if they are otherwise well, because by the time an eye looks red the exposure has already happened, and keeping a well child home costs school for very little benefit. What does help is handwashing, not sharing towels, and not rubbing the eyes. Please call your doctor the same day if there is eye pain, if bright light hurts, or if your child's vision changes — those are the symptoms that matter. My number is [PHONE].
Spanish. Estimadas familias: hemos visto varios casos de conjuntivitis en el salón de su hijo o hija. La mayoría de los casos son causados por un virus, lo que significa que las gotas antibióticas no ayudan, y casi siempre se resuelven solos. No estamos enviando a casa a los niños por tener el ojo rojo si por lo demás se sienten bien: para cuando el ojo se pone rojo, el contagio ya ocurrió, y faltar a la escuela no aporta ningún beneficio. Lo que sí ayuda es lavarse las manos, no compartir toallas y no frotarse los ojos. Llame a su médico el mismo día si hay dolor en el ojo, si la luz le molesta o si cambia la visión. Oficina de salud: [TELÉFONO].
A word about the individual letter. A note about a named child's eye is health-record correspondence, not a mass notification, and it should not go out through a broadcast tool as a matter of routine. Where a comms platform earns its place here is the class-level explanation and the policy letter. Kastr, like every tool in this category, will happily send an individual message to one family — that is a reason to be deliberate about which system you use for what, not a feature.
Questions people actually ask
Does a child with pink eye have to go home?
Under current guidance, not for the red eye alone. A child who is otherwise well can stay at school. What sends a child home is fever, eye pain, light sensitivity, changed vision, marked swelling, or simply being too unwell to take part — and those are reasons to be seen by a provider, not reasons peculiar to conjunctivitis. District policy may still say otherwise, in which case the policy applies and is worth revisiting.
Can we require 24 hours of antibiotic drops before return?
Many districts still do, and current guidance does not support it. Most conjunctivitis is viral, so the drops do nothing; requiring them obliges every family to obtain a prescription for a condition that usually does not need one, at the cost of an appointment and a co-pay. If the requirement is in your board policy, follow it and take the change to the board with the evidence.
How do I tell viral from bacterial conjunctivitis in the health office?
You largely cannot, and you should not present a guess as a finding. The classic distinctions — watery versus thick discharge, one eye versus both — overlap enough that clinicians examining the eye properly disagree about them. Describe what you observed, refer on the criteria that actually matter, and let the diagnosis come from someone who can examine the eye.
What do I send when another parent demands we exclude a child with pink eye?
A letter that explains the reasoning rather than citing authority, declines to discuss another student, tells them what actually protects their own child, and points the policy argument at whoever sets the policy. Keep the wording consistent across the nurse, the office and the principal, because inconsistency is what turns a phone call into a complaint.
When should a red eye be seen the same day?
Eye pain, sensitivity to light, any change in vision, marked swelling of the lid or around the eye, a chemical splash, or any injury to the eye. Those are referral criteria regardless of what the eye looks like, and they are the reason a health office should never be reasoning only about whether something is conjunctivitis.
