Can people who have had pink eye still get infected with it and how can I prevent it?

If you don't pay attention, you can be contagious!

There are many people who think that if you have pink eye, you won't get it again, and you have antibodies in your body, but this understanding is wrong.

If you have studied biology, you should know that many diseases are bacterial and viral, and antibodies only target the specific virus you have had, and there are countless viruses that cause a disease, and some unstable viruses can even mutate in the human body. It's like a virus.

The disease is highly contagious and can spread widely in a short period of time. The most important thing to prevent pink eye is to keep a distance from the source of infection, and everything you come into contact with is carrying the virus. Therefore, it is necessary to strengthen the propaganda work, do a good job in disinfection and isolation, and actively do it.

Patients are not allowed to swim in public pools. Handkerchiefs and washing utensils used by patients should be thoroughly disinfected.

At present, there is no specific drug for this disease, so it is not appropriate to use preventive eye drops.

Drug**: Rinse the conjunctival sac with normal saline, and after washing, you can prescribe morpholinoguanidine (viralin) eye drops, or neomycin eye drops, and at the same time drop cortisone acetate eye drops, which can reduce symptoms.

Traditional Chinese medicine clears away heat and detoxifies such as honeysuckle, coptis and other decoctions or eye washes.

Oral drugs include heat clearing and detoxification, Erding granules, bear bile pills, etc., which can lead to pink eye.

The disease is mainly transmitted by contact, most commonly through eye-hand-eye transmission. In addition, it is possible to be infected by touching towels, handkerchiefs, face washing utensils, electronic game consoles, computer keyboards, etc., or swimming or bathing in swimming pools and baths that have been touched by patients.

If not**, some will turn into chronic conjunctivitis.

1) If pink eye is found, it should be isolated in time, and all utensils should be used separately, and it is best to wash and dry them before use.

2) Pay attention to hand hygiene. Develop a good habit of washing your hands frequently, don't rub your eyes with dirty hands, and cut your nails frequently.

3) When suffering from pink eye, in addition to being active, you should avoid activities in public places, and do not use shared towels, basins, etc.

See a doctor! Be careful because it causes keratitis!

Tip 1: Don't rub your eyes with dirty hands.

Make it a habit not to rub your eyes with dirty hands and avoid using public towels and basins to avoid infection. Be sure to wash your hands with soap before touching your eyes after swimming, and preferably drop some antiviral eye drops (such as broad-spectrum antiviral eye drops "phthalobutyane") before and after swimming. Young children have weak immunity, so they should try to play in crowded places as little as possible, and maintain hand and eye hygiene.

Trick 2: Strictly disinfect and isolate with patients.

"Pink eye" is highly contagious, so you should avoid sharing a bed with family members with conjunctivitis, and wash your hands and disinfect immediately after contact with sick people. Towels, handkerchiefs, washbasins, stationery, toys, tools, utensils, etc., used by the sick person can become a vector of infection, so the patient's utensils should be used separately from healthy people and should be sterilized by boiling water for 10 minutes after use. Young children should be washed frequently, their nails should be cut, and they should be taught not to rub their eyes with their hands to prevent repeated infections.

If a family member or a colleague at work suffers from pink eye, other people can use eye drops for prevention.

Pink eye is divided into bacterial and viral, and bacterial ** infection is more common. In general, to avoid infection, don't rub your eyes with your hands, don't share face towels with others, and reduce the number of times you go to the pool. If you are not really at ease, you can find some eye drops of chloramphenicol and ofloxacin, and put them after contact with patients with pink eye.

If it is actively carried out**, it usually takes about a week to ten days to heal, and this requires a process.

Once found, immediately**, do not interrupt, and continue **1 week after the symptoms are completely gone, just in case**. **The eye can be irrigated, and when there is a lot of secretion in the affected eye, it is advisable to rinse the conjunctival sac with an appropriate rinse such as normal saline or 2% boric acid water, 2 to 3 times a day, and wipe the eyelid margin with a disinfectant cotton swab.

Eye drops or ointment can also be applied to the affected eye spot. If it is a bacterial infection, the most effective antibiotic eye drops can be selected according to the detected bacteria, according to the severity of the disease, every 2 3 hours or 1 time per hour, commonly used eye drops are 10% 20% sulfadia acetyl sodium, haloperic acid, chloramphenicol eye drops, etc., antibiotic eye ointment can be applied before going to bed at night, such as ciprofloxacin, chlortetracycline or tetracycline eye ointment, and the secretions need to be scrubbed clean before each dose to improve the efficacy. For conjunctivitis with mixed virus infection, in addition to the above drugs**, antiviral eye drops can also be used, such as oxybenzazole eye drops, peptamine emulsion for adenovirus, herpes net, acyclic guanosine eye drops, etc., 2 3 times a day, and interferon can also be used if necessary.
