What Do Poles Fall Ill With in November? Symptoms, Risks, and What to Especially Monitor During Late Autumn

November is a unique month regarding health. Across Poland - including in large cities such as Poznań - a dynamic increase in the number of cases related to seasonal infections begins. Deteriorating weather, falling temperatures, higher humidity, and shorter days affect the immune system, which is particularly strained at this time of year. Added to this are frequent temperature changes (moving from cold air into heated rooms), larger crowds of people, and seasonal vitamin D deficiency. All of this means that November brings the first major wave of infections - often dynamic, with many complications, even in previously healthy individuals.

Below is a description of the most common illnesses affecting Poles in November, along with indications of when to react more quickly and pay special attention to symptoms requiring medical consultation.

Influenza - the dominant virus of late autumn

November marks the beginning of the flu season. The illness usually starts abruptly: high fever, muscle aches, chills, a sharp cough, and general malaise. Unlike a common cold, the infection lasts longer and causes more severe symptoms. Patients in Poznań report an increasing number of sudden illnesses during this period, especially after gatherings in enclosed spaces - offices, lecture halls, and public transport. The flu in November can be the first signal of the upcoming winter peak in cases.

RSV - the virus that most often attacks the youngest

Although RSV is mainly associated with infants and young children, it is increasingly diagnosed in adults and seniors as well. Preschool and nursery groups are most at risk, which is why pediatricians in Poznań observe a sharp increase in cases specifically in November. The most common symptoms include coughing, wheezing, shortness of breath, and breathing difficulties. In children, RSV can lead to bronchiolitis or pneumonia, which requires a prompt medical evaluation.

Flu-like infections and colds - a mix of many viruses

November is a time when dozens of viruses circulate simultaneously, and the symptoms of individual infections often overlap. Patients report:

• low-grade fever or moderate fever,
• runny nose and nasal congestion,
• cough,
• sore throat,
• weakness and drowsiness.

In Poznań, the rapid spread of viruses is influenced by the intensive use of public transport and closed, heated rooms where transmission is easy.

Sinusitis - a frequent complication of November infections

Air humidity and frequent temperature changes put a particular strain on the mucous membranes. This causes nose and throat infections in November to very often turn into sinusitis. Pain when bending over, purulent nasal discharge, facial pain, and fever require a doctor's evaluation, especially if symptoms last more than 7-10 days. In Poznań, smog often adds to the problem, further irritating the respiratory tract.

Exacerbation of chronic diseases - asthma and COPD

November is one of the most difficult months for patients with respiratory diseases. Cold air, viral infections, and moisture can rapidly worsen symptoms of asthma and chronic obstructive pulmonary disease (COPD). For residents of Poznań, episodes of poor air quality contribute to the severity of symptoms. Shortness of breath, wheezing, an increasing cough, or a decrease in exercise tolerance are signals that a medical check-up is necessary.

Gastrointestinal infections - "winter" viruses of early autumn

Although the season for noroviruses and rotaviruses is more associated with mid-winter, in practice, many outbreaks already appear in November. The onset of the illness is usually sudden: nausea, vomiting, diarrhea, abdominal cramps, and fever. The greatest threat is dehydration, especially in children and the elderly. In Poznań, such infections often spread in kindergartens, canteens, and workplaces.

Ear infections - a painful consequence of autumn infections

Untreated or unresolved colds very often end in ear inflammation - especially in children. Acute pain, fever, ear discharge, or sudden hearing loss require urgent medical evaluation. In November, when infections are most prevalent, ENT clinics and family doctors in Poznań record the highest number of cases of this particular condition.

Cardiovascular problems - the effect of infections and weather changes

Viral infections in November can also affect the cardiovascular system. Some patients experience:

• heart palpitations,
• weakness,
• blood pressure spikes,
• chest pain.

Cold air and inflammation increase the risk of complications, especially in people with chronic diseases. November is a month when cardiology patients more frequently see a doctor due to worsening symptoms.

What else to watch out for in November?

• deteriorating mental health - short days and a lack of light increase the risk of low mood,
• muscle and joint pain associated with rapid temperature changes,
• recurring throat infections caused by indoor heating and dry air.

When to contact a primary care physician?

If infection symptoms worsen, persist for more than a few days, or are accompanied by warning signals (shortness of breath, high fever, severe pain, dehydration), a consultation with a primary care physician is recommended. Early diagnosis and appropriate treatment help avoid complications, which appear more frequently in November than in other autumn months.

People who are not assigned to any primary care physician can use the instructions available in the section rejestracja nowego pacjenta.

If traveling to the clinic is difficult, an available alternative is porady telemedyczne Poznań, which allows for a consultation without leaving home.
