Pneumonia is an infection that causes inflammation in one or both lungs. The pulmonary alveoli fill with fluid or pus making it difficult to breathe. [1] Pneumonia can be caused by bacteria, viruses, fungi or parasites. [1] Viruses are the most common cause of pneumonia in children, while in adults bacteria are a more common cause. [2]
Human metapneumovirus (HMPV) was first classified as a pneumovirus in 2001. It is a negative-strand RNA virus that is the second most common cause of lower respiratory infection in young children. Pneumoviruses are intermediate in size between viruses of the families Paramyxoviridae and Orthomyxoviridae. Cytoplasmic inclusions are considerably ...
RSV is the leading viral agent among pneumoviruses in pediatric upper respiratory diseases globally. New pneumoviruses have been discovered in the Netherlands among 28 children according to studies. Certain studies have isolated the children in hospitals to identify specific causes, contagion levels, and treatment options among those children. [2]
Virus classification is the process of naming viruses and placing them into a taxonomic system similar to the classification systems used for cellular organisms. Viruses are classified by phenotypic characteristics, such as morphology, nucleic acid type, mode of replication, host organisms, and the type of disease they cause.
Lack of scientific study to support the efficacy of any particular treatment No Blastomyces dermatitidis: Blastomycosis: KOH prep, cytology, or histology Itraconazole or ketoconazole: No Machupo virus: Bolivian hemorrhagic fever: No Clostridium botulinum; Note: Botulism is not an infection by Clostridium botulinum but caused by the intake of ...
Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [ 5 ] [ 6 ] [ 7 ] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
Pneumonia is a lung infection characterized by symptoms such as fever, chills, coughing, rapid or labored breathing, and chest pain. [28] For the elderly, those who contract pneumonia have also shown these lesser nonspecific symptoms, but also tend to show that they have tachypnea a few days before clinical certainty that they have contracted ...
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]
