Unlike ARVI, influenza affects not only the mucous membrane of the nasopharynx but also the deep parts of the lungs, causing pronounced intoxication: body aches, headaches, and a sharp increase in temperature to 39\u201340 \u00b0C within a few hours. In some patients\u2014especially the elderly or those with chronic illnesses\u2014it can lead to pneumonia, myocarditis, or even multiple organ failure. And yes, vaccination is one of the most reliable ways to protect against it, but it is not the only one. Many, for various reasons\u2014due to allergies, temporary contraindications, personal beliefs, or simply lack of access to the vaccine\u2014are looking for alternative prevention methods. And they exist. The main thing is to understand how the virus works, what areas of its vulnerability can be exploited, and which measures really work and which only create an illusion of safety.<\/p>\n<div

of the disease according to ICD-11<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>According to the International Classification of Diseases 11th Revision (ICD-11), influenza falls under the section \"Infectious and parasitic diseases\" (Chapter 1) and is coded as **BA40** \u2014 \"Influenza caused by influenza virus A,\" **BA41** \u2014 \"Influenza caused by influenza virus B,\" **BA42** \u2014 \"Influenza caused by influenza virus C,\" as well as **BA43** \u2014 \"Influenza caused by other influenza viruses\" (for example, D). Subtypes by strains are separately highlighted: for example, BA40.0 \u2014 influenza A(H1N1)pdm09, BA40.1 \u2014 A(H3N2), BA40.2 \u2014 A(H5N1), etc.<br \/>\nThis is important because not all \"influenza-like illnesses\" are true influenza. Many people refer to any acute respiratory infection with fever as influenza, but according to ICD-11, the diagnosis is made only with laboratory confirmation of the presence of the influenza virus. Other cases are ARVI (codes BA30\u2013BA3Z), caused by rhinoviruses, adenoviruses, respiratory syncytial viruses, and others. The difference is not only in terminology\u2014it affects treatment and prevention strategies. For example, antiviral drugs like oseltamivir are effective specifically against influenza viruses A and B, but are useless in rhinovirus infections.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%98%D1%81%D1%82%D0%BE%D1%80%D0%B8%D1%8F_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F_%D0%B8_%D0%B8%D0%BD%D1%82%D0%B5%D1%80%D0%B5%D1%81%D0%BD%D1%8B%D0%B5_%D0%B8%D1%81%D1%82%D0%BE%D1%80%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B8%D0%B5_%D1%84%D0%B0%D0%BA%D1%82%D1%8B\"><\/span>History of the disease and interesting historical facts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Influenza has been known to humanity for several centuries. The earliest reliable record of a mass outbreak dates back to 1580 in Italy\u2014at that time, the epidemic spread across Europe in three months, claiming thousands of lives. But the real \"age of influenza\" began in the 20th century\u2014especially after the 1918\u20131919 pandemic known as the \"Spanish flu.\" It claimed 20 to 50 million lives\u2014more than World War I. At the same time, the virus was particularly dangerous for young adults aged 20\u201340, rather than the elderly or children, as is usually the case. Modern studies have shown that the reason lies in the \"cytokine storm,\" when the immune system reacts excessively, destroying its own tissues.<br \/>\nAn interesting fact: the name \"Spanish flu\" arose not because the virus originated in Spain. The country was neutral in the war and did not impose censorship\u2014therefore, they freely reported on the disease. In other countries, reports were concealed to avoid undermining morale. Thus, Spain \"received\" the blame for simply reporting honestly.<br \/>\nAnother point: in 1957 and 1968, there were two more major pandemics\u2014the \"Asian\" and \"Hong Kong\" flu. Both were associated with the recombination of viruses between humans and birds. It was during this time that systematic tracking of strains began and databases were formed for vaccine development. Today, the WHO analyzes circulating strains annually and recommends the composition of vaccines for the next season\u2014this is a complex process that requires forecasting, as vaccine production takes 6\u20138 months.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%AD%D0%BF%D0%B8%D0%B4%D0%B5%D0%BC%D0%B8%D0%BE%D0%BB%D0%BE%D0%B3%D0%B8%D1%8F_%D1%81%D1%82%D0%B0%D1%82%D0%B8%D1%81%D1%82%D0%B8%D0%BA%D0%B0_%D0%B2%D0%BE%D0%B7%D0%BD%D0%B8%D0%BA%D0%BD%D0%BE%D0%B2%D0%B5%D0%BD%D0%B8%D1%8F_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F\"><\/span>Epidemiology: statistics on the occurrence of the disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>According to the WHO, annually, influenza affects between 51 million to 151 million people worldwide. This amounts to 1 billion cases of ARVI, of which 3 million are severe forms requiring hospitalization. The mortality rate from influenza and its complications is estimated at 290,000 to 650,000 people per year. In Russia, according to Rospotrebnadzor, in the 2023\u20132024 season, about 12.7 million cases of ARVI were registered, of which confirmed influenza cases were about 1.4 million. The peak occurred in the first decade of February, when the incidence level exceeded the epidemic threshold by 2.3 times.<br \/>\nThe risk is particularly high for certain groups:<br \/>\n\u2014 Children under 5 years old\u2014due to an immature immune system;<br \/>\n\u2014 People over 65 years old\u2014due to immune aging (thymic involution);<br \/>\n\u2014 Pregnant women \u2014 immunity is physiologically suppressed;<br \/>\n\u2014 People with chronic diseases: bronchial asthma, COPD, heart failure, diabetes, HIV\/AIDS.<br \/>\nStatistics show: in seasons when the vaccine strain poorly matches the circulating strain (for example, in 2014\u20132015), morbidity increases by 30\u201340%, and hospitalizations by 50%. This emphasizes that even with a vaccine, prevention should be comprehensive.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%93%D0%B5%D0%BD%D0%B5%D1%82%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B0%D1%8F_%D0%BF%D1%80%D0%B5%D0%B4%D1%80%D0%B0%D1%81%D0%BF%D0%BE%D0%BB%D0%BE%D0%B6%D0%B5%D0%BD%D0%BD%D0%BE%D1%81%D1%82%D1%8C_%D0%BA_%D0%B3%D1%80%D0%B8%D0%BF%D0%BF%D1%83\"><\/span>Genetic predisposition to influenza<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Genetics plays a role that is not as direct as in hereditary diseases. Studies show that certain gene variants influence susceptibility to the virus and the severity of the disease. For example:<br \/>\n\u2014 The **IFITM3** gene (interferon-induced transmembrane protein 3) encodes a protein that blocks the virus from entering the cell. Carriers of the rs2252-C mutation have an increased risk of severe influenza \u2014 especially in children and young adults.<br \/>\n\u2014 Polymorphisms in the **TLR3**, **TLR7** genes (toll-like receptors) reduce the immune system's ability to recognize viral RNA.<br \/>\n\u2014 The **HLA-DQB1*06:02** gene is associated with a milder course of influenza A(H1N1)pdm09.<br \/>\nHowever, these factors are not decisive. Even with an \"unfavorable\" genotype, a person may not get sick if they follow preventive measures. Conversely, with a \"protective\" genotype, a person may become severely ill with a high viral load and weakened immunity. Genetics is more of a risk modifier than a cause.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%A4%D0%B0%D0%BA%D1%82%D0%BE%D1%80%D1%8B_%D1%80%D0%B8%D1%81%D0%BA%D0%B0_%D0%B2%D0%BE%D0%B7%D0%BD%D0%B8%D0%BA%D0%BD%D0%BE%D0%B2%D0%B5%D0%BD%D0%B8%D1%8F_%D0%B3%D1%80%D0%B8%D0%BF%D0%BF%D0%B0\"><\/span>Risk factors for flu occurrence<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Risk factors can be divided into three groups: biological, behavioral, environmental.<br \/>\n**Biological:**<br \/>\n\u2014 Age (children and the elderly),<br \/>\n\u2014 Immunodeficient states (congenital or acquired),<br \/>\n\u2014 Chronic diseases of the lungs, heart, kidneys,<br \/>\n\u2014 Obesity (BMI \u2265 30) \u2014 adipose tissue produces pro-inflammatory cytokines, exacerbating the response to the virus,<br \/>\n\u2014 Pregnancy (especially the II\u2013III trimester).<br \/>\n**Behavioral:**<br \/>\n\u2014 Smoking \u2014 damages the cilia of the respiratory epithelium, reducing mechanical protection,<br \/>\n\u2014 Sleep deprivation (less than 6 hours a day) \u2014 suppresses the production of interferons,<br \/>\n\u2014 Stress and chronic fatigue \u2014 suppress T-cell immunity,<br \/>\n\u2014 Vitamin D deficiency \u2014 correlates with an increase in morbidity during winter.<br \/>\n**Environmental:**<br \/>\n\u2014 High population density (schools, offices, public transport),<br \/>\n\u2014 Low humidity (&lt;40%) \u2014 the virus remains active in aerosol for longer,<br \/>\n\u2014 Air pollution (PM2.5, NO\u2082) \u2014 exacerbates inflammation of the mucosa.<br \/>\nImportant: even one factor can significantly increase the risk.

diagnosis: how to distinguish it from ARVIh2&gt;<br \/>\nThe first symptoms of influenza often resemble ARVI, but there are key differences:<br \/>\n| Sign | Influenza | ARVI |<br \/>\n|&#8212;&#8212;&#8212;|&#8212;&#8212;-|&#8212;&#8212;|<br \/>\n| Onset | Acute, within 1\u20132 hours | Gradual, 1\u20132 days |<br \/>\n| Temperature | 38.5\u201340 \u00b0C, sharp | 37.5\u201338.5 \u00b0C, gradual |<br \/>\n| Aches | Severe, in muscles and joints | Moderate or absent |<br \/>\n| Cough | Dry, painful, later \u2014 with phlegm | Initially dry, quickly becomes wet |<br \/>\n| Runny nose | Appears later, mild | From the first hours, pronounced |<br \/>\n| Headache | Intense, pressing | Moderate, dull |<br \/>\n| Fatigue | Very pronounced, lasts 2\u20133 weeks | Moderate, resolves in 3\u20135 days |<br \/>\nLaboratory diagnostics include:<br \/>\n\u2014 **Rapid antigen tests** (immunochromatography): result in 15 minutes, sensitivity 50\u201370% \u2014 suitable for screening, but not for confirmation.<br \/>\n\u2014 **PCR (polymerase chain reaction)**: gold standard, sensitivity &gt;95%, allows determination of the virus type and subtype (A\/B, H1N1\/H3N2).<br \/>\n\u2014 **Serological method** (ELISA for antibodies): used retrospectively \u2014 increase in IgG titer in paired sera after 10\u201314 days.<br \/>\nRadiological methods (X-ray,

They block the release of viral particles from the cell. Effective only when taken within the first 48 hours of symptom onset. After that, the effect is minimal.<br \/>\n\u2014 **Baloxavir marboxil** (Xofluza) \u2014 inhibits the cap-dependent endonuclease of the virus, acts faster (effect within 24 hours), but is expensive and is not yet included in the standards of many countries.<br \/>\n**Symptomatic therapy**:<br \/>\n\u2014 Antipyretics: **paracetamol** (up to 4 g\/day) or **ibuprofen** (up to 1.2 g\/day). Aspirin is prohibited for children \u2014 risk of Reye's syndrome.<br \/>\n\u2014 For cough: for dry cough \u2014 **butamirate**, **levodropropizine**; for wet cough \u2014 **ambroxol**, **acetylcysteine**.<br \/>\n\u2014 For a runny nose: short-term (up to 5 days) \u2014 **xylometazoline**, **naphazoline**; better \u2014 saline sprays (saline solution, Aqualor).<br \/>\n\u2014 Hydration: at least 2\u20132.5 liters of fluid per day \u2014 water, compotes, herbal teas without sugar.<br \/>\n**Surgical treatment** \u2014 is not used. Exception \u2014 lung abscess or pleural empyema as a complication of bacterial pneumonia. Then drainage or thoracoscopy is required.<br \/>\nImportant: antibiotics for pure influenza **are not needed**. They do not affect the virus and can cause dysbiosis, allergies, resistance. They are prescribed only with confirmed bacterial superinfection (for example, with the growth of Streptococcus pneumoniae in sputum).<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%A1%D0%BF%D0%B8%D1%81%D0%BE%D0%BA_%D0%BB%D0%B5%D0%BA%D0%B0%D1%80%D1%81%D1%82%D0%B2_%D0%BF%D1%80%D0%B8%D0%BC%D0%B5%D0%BD%D1%8F%D0%B5%D0%BC%D1%8B%D1%85_%D0%BF%D1%80%D0%B8_%D0%B3%D1%80%D0%B8%D0%BF%D0%BF%D0%B5\"><\/span>List of medications used for influenza<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Here is the current list of medications approved in the Russian Federation and recommended by the Ministry of Health (as of 2025):<\/p>\n<table border=\"1\" cellpadding=\"5\" cellspacing=\"0\">\n<tr>\n<th>Group<\/th>\n<th>Preparation<\/th>\n<th>Release form<\/th>\n<th>Dosage (adults)<\/th>\n<th>Features<\/th>\n<\/tr>\n<tr>\n<td>Neuraminidase inhibitors<\/td>\n<td>Oseltamivir<\/td>\n<td>Capsules 75 mg<\/td>\n<td>75 mg 2 times\/day \u00d7 5 days<\/td>\n<td>Take with meals.

Control points:<br \/>\n\u2014 **Day 2\u20133**: there should be a trend towards a decrease in temperature (by 0.5\u20131 \u00b0C per day). If the temperature remains &gt;38.5 \u00b0C \u2014 a bacterial superinfection is possible.<br \/>\n\u2014 **Day 4\u20135**: the cough should become productive, and the general condition should improve.

In infants under 2 years, there is often no classic fever \u2014 instead, there is lethargy, refusal to eat, vomiting, diarrhea. The temperature may be \"hidden\" \u2014 up to 37.8 \u00b0C, but the child is lethargic and pale. The danger lies in the rapid development of respiratory failure. In children aged 2\u20135 years, laryngitis (\"croup\") is more common \u2014 hoarseness, \"barking\" cough, difficulty breathing. Immediate assistance is crucial here: inhalation with adrenergic agonists (e.g., phenylephrine) and glucocorticoids (budesonide).<br \/>\nIn adolescents and young adults, influenza often masquerades as a \"severe cold,\" but with it comes a sharp fever, headache, and inability to get out of bed. This group suffered the most in 1918 \u2014 due to hyperreaction of the immune system.<br \/>\nIn elderly people (over 65), symptoms may be muted: temperature up to 37.5 \u00b0C, weakness, confusion, worsening of chronic diseases. Often, influenza \"reveals itself\" already against the background of pneumonia. Therefore, in the elderly, any deterioration in condition should be checked for influenza \u2014 even without fever.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%92%D0%BE%D0%BF%D1%80%D0%BE%D1%81%D1%8B_%D0%B8_%D0%BE%D1%82%D0%B2%D0%B5%D1%82%D1%8B_%D1%81%D0%B0%D0%BC%D1%8B%D0%B5_%D1%87%D0%B0%D1%81%D1%82%D1%8B%D0%B5_%D0%B7%D0%B0%D0%BF%D1%80%D0%BE%D1%81%D1%8B_%D0%BF%D0%BE%D0%BB%D1%8C%D0%B7%D0%BE%D0%B2%D0%B0%D1%82%D0%B5%D0%BB%D0%B5%D0%B9\"><\/span>Questions and answers: the most frequent user inquiries<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong>Question 1: Can the flu be cured in 1 day?<\/strong><br \/>\nNo. Even with the intake of oseltamivir in the first 24 hours, the virus continues to replicate for 3\u20135 days. The drug reduces the duration of fever by 1\u20132 days and lowers the risk of complications, but does not \"kill\" the virus instantly. Promises of \"you'll recover in a day\" are a marketing ploy. Real recovery takes 5\u20137 days in mild cases.<br \/>\n<strong>Question 2: Why does a cough persist for a long time after the flu?<\/strong><br \/>\nAfter the flu, the bronchial mucosa remains damaged \u2014 the cilia of the epithelium regenerate in 2\u20133 weeks. Coughing is a protective reaction that clears the airways. If the cough is dry and painful \u2014 central antitussives (codeine, butamirate) can be used, but not for more than 5 days. If it lasts longer than 3 weeks \u2014 a CT scan of the lungs is needed to rule out bronchiectasis or tuberculosis.<br \/>\n<strong>Question 3: Does garlic or onion help against the flu?<\/strong><br \/>\nGarlic contains allicin \u2014 a compound with antimicrobial activity in vitro. But in real conditions: to achieve a therapeutic concentration in the blood, one would need to eat 10\u201315 cloves of fresh garlic at once \u2014 which would cause rot and gastritis. Studies show that regular consumption of garlic reduces the risk of ARVI by 15\u201320%, but not the flu. Onion \u2014 similarly. This is prevention, not treatment.<br \/>\n<strong>Question 4: Is it okay to walk while having the flu?<\/strong><br \/>\nNo. During fever and intoxication, the body spends energy fighting the virus. Physical exertion increases the load on the heart and the risk of myocarditis. Even a light walk outside with a temperature &gt;38 \u00b0C poses a risk of complications. You can only walk after normalizing the temperature and in the absence of weakness \u2014 and even then, not for more than 15 minutes, during warm hours of the day.<br \/>\n<strong>Question 5: How to protect yourself from the flu without a vaccine \u2014 is it possible?<\/strong><br \/>\nYes, it is possible \u2014 but only comprehensively. No single method provides 100% protection. An effective strategy includes:<br \/>\n\u2014 Daily hand washing with soap (at least 20 seconds),<br \/>\n\u2014 Wearing a mask in transport and crowded places (FPP2 or surgical),<br \/>\n\u2014 Maintaining humidity of 40\u201360% (humidifier or wet towels),<br \/>\n\u2014 Sleeping at least 7 hours,<br \/>\n\u2014 Balanced diet with sufficient protein and vitamin D,<br \/>\n\u2014 Avoiding contact with sick individuals (at least 1 meter distance),<br \/>\n\u2014 Using antiviral medications prophylactically \u2014 only as prescribed by a doctor (for example, oseltamivir 75 mg once a day for 7 days upon contact with an infected person).<br \/>\nThis is not a \"miracle remedy,\" but a system of measures that reduces the risk of infection by 2\u20133 times. In combination with vaccination \u2014 almost complete protection. Without the vaccine \u2014 everything depends on your discipline and environment.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%A2%D0%B8%D0%BF%D0%B8%D1%87%D0%BD%D1%8B%D0%B5_%D0%BE%D1%88%D0%B8%D0%B1%D0%BA%D0%B8_%D0%BF%D1%80%D0%B8_%D0%BF%D1%80%D0%BE%D1%84%D0%B8%D0%BB%D0%B0%D0%BA%D1%82%D0%B8%D0%BA%D0%B5_%D0%B3%D1%80%D0%B8%D0%BF%D0%BF%D0%B0_%D0%B8_%D0%BA%D0%B0%D0%BA_%D0%B8%D1%85_%D0%B8%D0%B7%D0%B1%D0%B5%D0%B6%D0%B0%D1%82%D1%8C\"><\/span>Typical mistakes in flu prevention and how to avoid them<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>1. <strong>Mistake: \"I have already been sick \u2014 now I have immunity for a year\"<\/strong><br \/>\nThe flu virus mutates every season. Even if you had A(H3N2) in winter 2025, a new strain A(H3N2)v may circulate in spring 2026 \u2014 and you will get sick again. Immunity to a specific strain lasts 6\u201312 months, but not to new variants.<br \/>\n2. <strong>Mistake: \"I take 3 g of vitamin C a day \u2014 I definitely won't get sick.\"<\/strong><br \/>\nHigh doses of vitamin C (more than 1 g\/day) do not reduce the risk of flu. They can cause kidney stones, diarrhea, allergies. 200 mg per day is enough \u2014 this is sufficient to maintain immunity.<br \/>\n3. <strong>Mistake: \"I rinse my nose with saline every day \u2014 the virus won't get through.\"<\/strong><br \/>\nNasal rinsing is helpful for a runny nose, but not as prevention. The virus enters through the eyes, mouth, and microcracks in the mucosa. Even with perfect nasal hygiene, you can get infected when talking to a sick person at a distance of 1.5 meters.<br \/>\n4. <strong>Mistake: \"If the temperature is 37.2 \u2014 it's not the flu, I can go to work.\"<\/strong><br \/>\nIn the elderly and immunosuppressed, flu can start without fever. But even with a low-grade fever (37.2\u201337.8 \u00b0C) and weakness \u2014 you are already contagious. The virus is shed 1 day before symptoms and up to 5\u20137 days after they disappear. It's better to stay home for at least 5 days.<br \/>\nHow to avoid it? Make a \"prevention plan\" for the season:<br \/>\n\u2014 2 weeks before the epidemic threshold: check your vitamin D level (optimal \u2014 40\u201360 ng\/ml),<br \/>\n\u2014 Buy quality FPP2 masks and a humidifier,<br \/>\n\u2014 Learn to wash your hands properly (the back of the hands, under the nails),<br \/>\n\u2014 Agree in advance with your doctor about the possibility of prescribing antivirals at the first symptoms.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%97%D0%B0%D0%BA%D0%BB%D1%8E%D1%87%D0%B5%D0%BD%D0%B8%D0%B5_%D1%87%D1%82%D0%BE_%D1%80%D0%B0%D0%B1%D0%BE%D1%82%D0%B0%D0%B5%D1%82_%D0%B0_%D1%87%D1%82%D0%BE_%E2%80%94_%D0%BB%D0%B8%D1%88%D1%8C_%D0%B8%D0%BB%D0%BB%D1%8E%D0%B7%D0%B8%D1%8F\"><\/span>Conclusion: what works and what is just an illusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>It is possible to protect yourself from the flu without a vaccine \u2014 but only if you act systematically and consciously.

Your task is not to \"survive the season,\" but to minimize the risk of infection and the severity of the illness. If you cannot get vaccinated \u2014 do not despair. There are many other tools. The main thing is not to rely on just one, but to combine them. And always listen to your body: if you feel that \"something is wrong\" \u2014 it's better to be cautious than to treat complications later.<br \/>\nStay healthy.
