From a Simple Cough to a Diagnosis: Everything You Need to Know About Respiratory Infections
Highlights:
- Respiratory tract infections – from A to Z
- Signs of bacterial and viral infection
- Prevention – the key to a peaceful everyday life
Respiratory infections are the most common reason for visiting a GP, especially during the fall and winter seasons. Statistics show that adults experience an average of 2-4 respiratory infections per year, while children experience 6-8. During the cold months, the frequency increases dramatically due to a combination of factors – closed spaces with poor ventilation, reduced sunlight leading to vitamin D deficiency, and others.
Cough, sore throat, and fever are symptoms that we often underestimate. “It will go away on its own” or “the cough will go away on its own” are phrases we have all said. The reality, however, is that these seemingly harmless symptoms sometimes hide serious illnesses that require timely intervention.
Respiratory infections are inflammatory processes affecting various parts of the respiratory system – from the nose and throat to the lungs. They can be caused by hundreds of different microorganisms and vary in severity. Knowing the basic mechanisms, symptoms, and methods of prevention allows us to protect our health and that of our loved ones.
What are respiratory tract infections?
The respiratory system is divided into two main parts. The upper respiratory tract includes the nose, nasopharynx, pharynx, and larynx. Infections here are most common and include rhinitis (runny nose), sinusitis (inflammation of the sinuses), pharyngitis (sore throat), tonsillitis (strep throat), and laryngitis (inflammation of the larynx).
The lower respiratory tract includes the trachea, bronchi, and lungs. Infections in this area are more serious and include tracheitis, bronchitis, bronchiolitis, and pneumonia. Tuberculosis also falls under lower respiratory tract infections and remains a significant health problem to this day.
The causes of respiratory infections are varied:
- Viruses – responsible for most acute respiratory infections. The most common are rhinoviruses, coronaviruses (including SARS-CoV-2), influenza viruses types A and B, parainfluenza viruses, adenoviruses, and respiratory syncytial virus (RSV).
- Bacteria – streptococci, staphylococci, pneumococci, Haemophiles influenzae, mycoplasma, and chlamydia. They often cause secondary infections after a viral illness.
- Fungi – rarer causes, usually in people with weakened immune systems. Candida and Aspergillus are the most common fungal pathogens.
Infections are transmitted in several main ways. Airborne transmission is the most common – when coughing, sneezing, or talking, an infected person expels millions of microscopic droplets containing pathogens. These can remain in the air for minutes to hours, especially in enclosed spaces. The contact route involves touching contaminated surfaces and then transferring the microbes to the face. Studies show that we touch our faces an average of 23 times per hour, which explains the easy spread of infections.
Symptoms and when to seek medical attention
The main signs of a respiratory infection develop gradually or suddenly, depending on the cause. The cough can be dry (irritating, without phlegm) or wet (productive, with phlegm). The color of the phlegm cannot completely distinguish between a viral and a bacterial infection.
Sore throat ranges from mild irritation to severe pain when swallowing. Temperature is also indicative – slightly elevated (up to 38°C) in viral infections and high (above 38.5°C) in bacterial infections. Shortness of breath is an alarming symptom, indicating involvement of the lower respiratory tract.
Distinguishing between viral and bacterial infections is important for proper treatment. Viral infections usually start gradually with a runny nose, sneezing, and throat irritation. The temperature rarely exceeds 38.5°C, and the general condition is relatively good. Symptoms peak in 2-3 days and gradually subside in 7-10 days.
Bacterial infections often start more abruptly, with high fever, severe pain (in the throat, head, or chest), and pronounced fatigue. Purulent nasal discharge and sputum, as well as enlarged and painful lymph nodes, occur in both bacterial and viral infections.
Timely medical consultation is critical in certain situations:
- Temperature above 39°C that is not affected by fever-reducing medication or lasts for more than 3 days
- Shortness of breath or difficulty breathing, especially at rest
- Bloody or rusty brown mucus
- Severe headache with neck stiffness – a possible sign of meningitis
- Worsening after initial improvement – may indicate a secondary bacterial infection
In children under 3 years of age, adults over 65 years of age, pregnant women, and people with chronic diseases, consultation with a specialist should be considered earlier. In these individuals, infections are more likely to be severe and can progress rapidly.
Treatment and support for the body
The general principles of treatment for respiratory infections begin with ensuring appropriate conditions for recovery. Rest is essential – the body needs energy to fight the infection, and physical exertion can worsen the condition and prolong recovery.
Hydration is critically important – a minimum of 2.5-3 liters of fluids per day in the form of water, hot teas, soups, and broths is recommended. Fluids thin secretions, facilitate coughing, and help eliminate toxins.
Treatment of symptoms includes fever-reducing medication for temperatures above 38.5°C (or discomfort), painkillers for headaches and muscle aches, and topical preparations for the throat and nose.
Antibiotics are only effective against bacterial infections, and their misuse is a serious problem. They are prescribed for proven bacterial infections (through microbiological testing or based on symptoms) and complications such as pneumonia or sinusitis. Antibiotics are also prescribed when symptoms persist for more than 10 days without improvement and for high-risk patient groups. It is important to complete the entire course of treatment, even if there is improvement, to prevent the development of resistance.
Supporting the immune system is key to rapid recovery and preventing complications. A balanced diet should include:
- enough protein (for antibody production)
- vitamin C (citrus fruits, kiwis, red peppers)
- vitamin D (fish, eggs)
- zinc (meat, nuts, seeds)
- selenium (Brazil nuts, fish)
Probiotics support intestinal immunity, which accounts for 70% of overall immune protection. Quality sleep of 7-9 hours is necessary for the regeneration of immune cells.
In this context, immunostimulants such as Stamatin are a valuable addition to overall body care. The product contains a scientifically selected combination of active substances that support the normal functioning of the immune system. Its antioxidant properties protect cells from oxidative stress, which increases during infections. Stamatin can be taken both preventively to maintain a strong immune system and at the first signs of infection to speed up recovery.
How to protect yourself from respiratory infections
Prevention is always easier than treatment. The main preventive measures include:
- avoiding close contact with sick people (keeping a distance of at least 1.5 meters)
- frequent and proper hand hygiene (washing with soap for at least 20 seconds and subsequent disinfection)
- avoiding touching your face, eyes, and nose with unwashed hands
Ventilating rooms is extremely important – it is recommended to open windows for 10-15 minutes every 2-3 hours, even in winter.
Strengthening the immune system is a long-term strategy that includes:
- Regular physical activity – moderate exercise for 30-45 minutes a day stimulates the production of immune cells and improves circulation. Intense exercise is not necessary – brisk walking, swimming, or yoga are perfectly sufficient.
- Stress management – chronic stress suppresses immune function by increasing cortisol. This hormone reduces lymphocyte production and suppresses the inflammatory response needed to fight infections. Techniques such as deep breathing, meditation, or 10 minutes of calm music a day can significantly reduce stress.
- Quitting smoking – cigarette smoke damages the cilia in the airways that clear away microbes. In smokers, this “self-cleaning” is disrupted, allowing pathogens to penetrate deeper into the lungs.
Prevention
The best protection against respiratory infections is a combination of vaccination, healthy habits, and sensible support for the immune system. Preventive intake of Stamatin during the fall and winter seasons provides additional protection for the body, as the product’s ingredients help the immune system fight off infection on its own.
Vaccination remains the most effective method of protection against specific infections. The flu vaccine is recommended annually, especially for high-risk groups, and reduces the risk of illness by 40-60% when there is a good match with the circulating strains.
The pneumococcal vaccine protects against Streptococcus pneumoniae, the most common cause of bacterial pneumonia. The pertussis vaccine is part of the mandatory immunization schedule, but immunity weakens over time and booster doses are recommended.
Respiratory infections will continue to be part of our lives, but with the right knowledge, timely response, and adequate prevention, we can significantly reduce their impact. The combination of basic hygiene measures, a healthy lifestyle, and immune support with quality products such as Stamatin gives us all the tools we need for successful protection. It is important not to underestimate the symptoms, to respond in a timely manner, and to invest in prevention rather than wait for complications to arise.

FAQ:
Can I get sick again from the same virus during the season?
- Yes, this is possible with some viruses. For example, there are over 200 types of rhinoviruses that cause the common cold, so you can catch different variants during a single season. Influenza viruses can also mutate during an epidemic. Immunity after an infection usually lasts 3-12 months depending on the virus, but with a weakened immune system, this period may be shorter.
Why do antibiotics sometimes “help” with viral infections?
- This is a misconception—antibiotics do not work on viruses. The apparent improvement is due to natural recovery, which coincides with their use. In some cases, however, the viral infection weakens the mucous membranes and a secondary bacterial infection develops (e.g., sinusitis after a cold), in which case antibiotics do help. That is why a doctor’s assessment is important.
Should I avoid dairy products when I have a cough and runny nose?
- This is a myth with no scientific basis. Dairy products do not increase mucus production, but they can temporarily thicken saliva, creating a feeling of more secretions. In fact, yogurt and kefir are beneficial because of their probiotics.
