Title: Respiratory Illnesses Sweep Germany: 7 Million Affected

Germans are grappling with a surge in respiratory illnesses, with over 7 million people currently infected. The Institut Robert Koch (RKI) reports a high level of respiratory illnesses, making it clear that the number of cases is already high for this time of year, according to their latest report covering the week of September 30th to October 6th, 2024. The incidence of acute respiratory infections (ARE) stands at around 7.3 million people, whether or not they have consulted a doctor.

Common cold viruses and Sars-CoV-2 are primarily responsible for this increase. However, it’s not always easy to distinguish between a common cold, corona, or flu. Focus.de helps explain the differences between these pathogens.

Understanding the Differences

  • Covid-19 (Sars-CoV-2)
    Symptoms range from headache, fatigue, fever, dry cough, loss of appetite, and night sweats. More rare symptoms include diarrhea, skin irritation, red eyes, or mouth inflammation. Particles are transmitted through breathing, coughing, sneezing, or speaking. The contagion period usually lasts up to 10 days.

  • Flu (Influenza Virus)
    Unlike a common cold, the flu hits harder and symptoms onset abruptly. These include high fever, severe headache, muscle aches, and overall weakness. Other symptoms may include nausea, vomiting, or diarrhea, but they’re less common. People with the flu are contagious for up to 7 days after symptoms appear, and illness typically lasts 5-7 days.

  • Respiratory Syncytial Virus (RSV)
    RSV particularly affects infants and young children, but it can also cause severe symptoms in adults. Symptoms include fever, persistent coughing, and respiratory difficulty. In infants, RSV can lead to bronchiolitis or pneumonia. The virus is extremely contagious, with a contagion period of up to 8 days. Severe cases may require hospitalization.

  • Common Cold (Rhinovirus)
    Colds are the mildest of these afflictions, with gradual symptoms like nasal congestion, sneezing, sore throat, and light cough. Fever is rare and usually doesn’t exceed 38°C. Unlike flu or COVID-19, a cold doesn’t cause severe fatigue or high fever. Symptoms usually disappear within 7-10 days.

The surge in respiratory illnesses underscores the importance of taking preventive measures, such as regular hand washing, face mask use, and staying home when sick, to help curb the spread of these viruses. If you experience any concerning symptoms, consult a healthcare professional for proper diagnosis and treatment.
