[1] Viruses are the most common cause of pneumonia in children, while ...
Four million per year [ 12 ][ 13 ] Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. [ 3 ][ 14 ] Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. [ 15 ] The severity of the condition is variable.
Classification of pneumonia. Pneumonia can be classified in several ways, most commonly by where it was acquired (hospital versus community), but may also by the area of lung affected or by the causative organism. [1] There is also a combined clinical classification, which combines factors such as age, risk factors for certain microorganisms ...
A runny nose, cough, congestion or sore throat can arise because of any of the three viruses or a common cold. But a loss of taste and smell is more commonly associated with Covid than with flu or ...
Human metapneumovirus (HMPV or hMPV) is a negative-sense single-stranded RNA virus of the family Pneumoviridae [ 1 ] and is closely related to the Avian metapneumovirus (AMPV) subgroup C. It was isolated for the first time in 2001 in the Netherlands by using the RAP-PCR (RNA arbitrarily primed PCR) technique for identification of unknown ...
Fever, sweating, and shaking chills. Shortness of breath. Rapid, shallow breathing. Sharp or stabbing chest pain that gets worse when you breathe deeply or cough. Loss of appetite. Low energy and ...
Potential vaccines being researched fall into five broad categories: live-attenuated, protein subunit, vector-based, virus particle subunit, and messenger RNA. Each targets different immune responses, and thus may be better suited to prevent disease in different at-risk groups. Live-attenuated vaccines have shown some success in RSV-naive infants.
The symptoms of COVID-19 are variable depending on the type of variant contracted, ranging from mild symptoms to a potentially fatal illness. [1][2] Common symptoms include coughing, fever, loss of smell (anosmia) and taste (ageusia), with less common ones including headaches, nasal congestion and runny nose, muscle pain, sore throat, diarrhea ...
