Respiratory Infection Symptoms

Primarily respiratory infections are two types – lower respiratory infections and upper respiratory infections. In upper respiratory infections, pharynx, sinus and nose are affected mainly, whereas lower respiratory infection mainly afflicts the respiratory system from trachea to lungs. Mostly, upper respiratory infections are developed by the microbial pathogens such as bacteria and viruses. The signs and symptoms of these infections appear after 1 – 3 days, after the virus attacks the respiratory system. Sharing infected food, hand shaking, touching the mouth or nose with the infected hands may cause upper respiratory infections. People who smoke regularly are more vulnerable to lower respiratory infections. It is said that pneumonia causes lower respiratory infections.

Respiratory Infection Symptoms:

People are advised to know whether they are suffering from lower respiratory infection or upper respiratory infections. Although their symptoms are almost similar, there is a very minute difference. Thus, it can be difficult for identifying, whether the infection is because of malfunctioning in lower or upper respiratory system.

Symptoms of Lower Respiratory Infection:

Lower respiratory infections are most serious and severe compared to upper respiratory infections. Cough is the primary symptom of lower respiratory infection. It is very intense and brings up phlegm that is stained with blood. Body pain, a tight feeling in chest, sore throat, blocked nose, sinusitis, headache, wheezing and breathlessness are other symptoms of lower respiratory infection. Fatigue and high fever are other symptoms.

Symptoms of Upper Respiratory Infections:

Runny or stuffy nose, facial pressure, muscle ache, sneezing, sore throat and headache are the most common symptoms of upper respiratory infections. Excess mucous and nasal congestion are other upper respiratory infection symptoms. In some cases, coughing up blood can also be a symptom of this condition. Laryngitis, bronchitis, sinusitis, common cold and ear infection are other upper respiratory infection symptoms. In many cases, these symptoms disappear in a couple of weeks.

Mostly, respiratory infections can be cured without any treatment. But, sometimes infection may become severe and needs proper treatment. If you observe any of the above discussed symptoms, you are advised to consult the health care provider immediately.
