How does a common ARVI proceed?
For most people, the disease develops according to a predictable pattern. Knowing this scenario saves you from both unnecessary medications and unnecessary anxiety: almost everything that frightens you on the fourth or fifth day actually belongs to the normal phase of recovery.
- Дни 1–2: першение и боль в горле, чихание, заложенность носа, ломота, слабость, иногда температура до 38 °C.
- Дни 3–4: пик diseases — обильные прозрачные выделения of носа, головная боль, снижение обоняния; температура чаще уже идёт вниз.
- Дни 4–6: выделения густеют, становятся жёлтыми или зеленоватыми, присоединяется кашель. Это нормальный этап, а не «присоединение бактерий».
- Дни 7–10: основные симптомы уходят, остаются лёгкая заложенность и кашель.
- До 2–3 недель может сохраняться остаточный сухой кашель: реснитчатый эпителий бронхов восстанавливается дольше, чем слизистая носа.
Why is an antibiotic useless against a virus?
Antibiotics were created against bacteria - independent living cells with their own membrane, ribosomes and metabolism. The drug hits these structures: it destroys the cell wall, prevents the bacteria from synthesizing protein or copying DNA. The virus is structured fundamentally differently: it is genetic material in a protein shell that does not have any of these targets. Requiring an antibiotic to work on a virus is about the same as fixing a radio with a plumbing wrench.
- The antibiotic does not shorten the duration of ARVI and does not reduce the temperature
- It does not prevent complications - the prescription “to prevent pneumonia” is not supported by research
- Side effects are real: diarrhea, nausea, allergic reactions, candidiasis, in children - disturbance of intestinal microflora
- Each unnecessary course selects resistant bacteria, and when the antibiotic is actually needed, it may not work
- A short course of two or three days “just in case” is especially harmful: it does not cure anything, but manages to train the bacteria
Antiviral agents and immunomodulators, which are offered in pharmacies for any cold, deserve a separate discussion. Proven antiviral therapy exists for influenza, COVID-19, herpes viruses and HIV - that is, for specific pathogens with a known target. For most common cold viruses, there is no specific treatment, and this is normal: the immune system copes with them on its own within a week.
When is an antibiotic really needed?
A bacterial complication is not a fiction, it happens. It just doesn’t develop in everyone and not on the second day of illness. The doctor begins to think about him when the picture goes beyond the usual scenario.
- Two-wave course: it became noticeably better, but on the 5th–7th day the temperature rose again and health worsened
- Fever above 38 °C lasts longer than five days without a tendency to decrease
- Unilateral bursting pain in the face, above the eyebrow or under the eye, purulent discharge for more than 10 days - suspicion of bacterial sinusitis
- Severe sore throat, plaque on the tonsils, enlarged painful cervical lymph nodes with a high temperature and almost complete absence of runny nose and cough - possible streptococcal sore throat
- Ear pain, hearing loss, discharge from the ear canal - acute otitis media
- Shortness of breath, chest pain, moist rales, cough with purulent sputum - pneumonia must be excluded
A separate and very common situation is a lingering cough after ARVI. In itself, it is not a sign of pneumonia and not an indication for an antibiotic: the ciliated epithelium of the bronchi takes weeks to recover, and coughing at this time is natural. Other things are alarming: coughing in attacks until vomiting, wheezing, nocturnal attacks of suffocation, coughing for more than three weeks without the slightest tendency to improve. In such cases, they look not for bacteria, but for the cause - whooping cough, bronchial asthma, allergies, sometimes a foreign body in a child, or reflux of stomach contents into the esophagus in an adult.
What really helps with ARVI
Treatment of ARVI is not about fighting the virus, but about supporting the person while the immune system does its job. The task comes down to three points: to relieve symptoms, not to interfere with recovery, and not to cause harm with unnecessary means. Everything that really works is inexpensive and sold without a prescription.
- Drinking plenty of fluids thins mucus and replenishes losses during fever; water, compote, weak tea, broth are suitable
- Cool, humid air in the room: dry air dries out the mucous membranes and makes the cough stronger than any virus
- Rinsing the nose with saline solution - mechanically removes mucus, safe for both children and pregnant women
- Antipyretic when you feel unwell, and not “according to the number on the thermometer”: a temperature of 38 °C in itself does not cause harm in a person without chronic diseases
- Vasoconstrictor nasal drops - in a short course, no longer than 5-7 days, otherwise medicinal rhinitis develops
- Warm saline lozenges and gargles for sore throats provide simple and safe relief.
- Raising the head of the bed: lying down makes nasal congestion worse and sleep becomes worse
- Rest and sleep: working “on your feet” with a fever prolongs the disease and increases the risk of complications
Honey, warm drinks and rest do provide relief, and there is nothing unscientific about this - they soften the symptoms. But none of these methods “kill the virus” or reduce the disease: the viral infection is defeated by one’s own immune response, which takes seven to ten days.
What not to do
A fair portion of the harm in acute respiratory viral infections comes not from the disease itself, but from the treatment. Below are collected habits that are either useless or create a real risk, and you should give them up first.
- Start antibiotics on your own, on the advice of relatives or from the remnants of the previous package
- Reduce any temperature immediately, without waiting for 38.5 °C in an adult without chronic diseases
- Rubbing a child with alcohol or vinegar - they are absorbed through the skin and are dangerous
- Putting mustard plasters and steam inhalations over a saucepan for children: the risk of burns to the respiratory tract is greater than the benefit
- Drip vasoconstrictor drugs into the nose for weeks
- Demand to “drip the antibiotic intravenously to make it faster”: the route of administration does not turn the virus into bacteria
- Go to work or kindergarten in the first days when a person is most contagious
Prevention that works
There is no 100% protection against respiratory viruses, and that’s okay: there are too many of them and they are constantly changing. But the following actually reduces both the frequency of diseases and their severity - unlike popular remedies “to strengthen the immune system,” which have no evidence base.
- Мытьё рук с мылом после улицы, транспорта и общественных мест — самая эффективная и самая недооценённая мера, потому что большинство респираторных вирусов передаётся через руки и предметы.
- Привычка не трогать лицо руками: вирус попадает в организм через слизистую носа и глаз.
- Ежегодная прививка от гриппа для детей, пожилых, беременных и людей с хроническими болезнями — от гриппа она защищает, от остальных вирусов нет, но именно грипп даёт тяжёлые осложнения.
- Регулярное проветривание помещений и увлажнение воздуха зимой.
- Отказ от курения: у курильщиков респираторные инфекции протекают дольше и чаще осложняются.
- Достаточный сон и сбалансированное питание — банально, но реально влияет на восприимчивость.
