A persistent cough is the most obvious outward sign of chronic obstructive pulmonary disease (COPD). It develops gradually over several years.
COVID-19 is caused by an infection with SARS‑CoV‑2. The disease may be mild or very severe. Observing the public health rules and getting the coronavirus vaccine are important preventive measures.
Pneumonia typically brings on a sudden high fever, coughing and breathlessness. People without any pre-existing conditions normally recover after a few weeks.
With acute bronchitis, the lower airways (bronchi) become temporarily inflamed. Initially, there is a dry cough but phlegm may later be coughed up from the airways.
An allergy occurs when the immune system has an overly sensitive reaction to a harmless substance such as plant pollen. There are various ways to treat an allergy.

Lung cancer is one of the most common types of cancer. Around 57,000 people get lung cancer every year in Germany.
Many children and adults are affected by hay fever in the spring and summer months, when plants grow and bloom. It is caused by an allergic reaction to pollen in the air, affecting the upper airways.
A pulmonary embolism is when a blood vessel supplying blood to a lung gets blocked. This kind of blockage is an emergency as it can be life-threatening.
MERS is a viral infection of the respiratory tract, which occurs predominantly on the Arabian Peninsula. The virus is mainly transmitted from dromedary camels to humans.
Flu is a common respiratory infection in pigs, caused by influenza viruses that occur primarily in these animals. In rare cases, people can become infected and ill as a result.
SARS is an infectious disease of the lungs, which is caused by the SARS-CoV coronavirus. The virus first appeared at the end of 2002 and spread to more than 30 countries until the middle of 2003.
Bird flu (avian influenza) primarily affects birds but can also be transmitted to humans through close contact with infected birds. Infection is rare but often has severe symptoms.
Inflammation of the epiglottis is usually caused by bacteria. Immediate treatment is required, as it can cause acute shortness of breath.
Acidosis is a condition in which the body’s pH balance is disrupted. As a result, the pH value of the blood drops and becomes “acidic”. This acidity is usually due to an underlying illness.
Pleural effusion is a build-up of fluid in the pleural space, i.e. the area between the lungs and the chest wall. Shortness of breath and chest pain are typical signs.

People with obstructive sleep apnea (OSA) find it difficult to breathe while sleeping and have their breathing interrupted – usually without noticing it. So sufferers are very sleepy during the day.
In an animal allergy it is not the fur that causes a reaction, but proteins that are found in the animal’s saliva, for instance. Avoiding contact with the animal can help, as can taking medication.
It is true that the plague is now rare, but it has not been completely eradicated. Pneumonic plague may occur on its own or as a result of bubonic plague.
