Influenza, commonly known as "the flu", is an infectious disease caused by an influenza virus. Symptoms can be mild to severe. The most common symptoms include: high fever, runny nose, sore throat, muscle and joint pain, headache, coughing, and feeling tired. These symptoms typically begin two days after exposure to the virus and most last less than a lty: Infectious disease. Influenza is caused by infection of the respiratory tract with influenza viruses, RNA viruses of the Orthomyxovirus genus. Influenza viruses are classified into 4 types: A, B, C, and D. Only virus types A and B commonly cause illness in humans.
This is Part 2 of 2 Anatomy Video Lectures on the Respiratory System by Professor Fink. In this Video Lecture, Professor Fink describes the . Several other zoonotic coronaviruses are endemic in the human population. They cause about a third of mild respiratory tract infections (rhinorrhea (runny nose), headache, sneezing, malaise and sore-throat). Coryza (acute inflammation of the upper respiratory tract) with fever and cough is .
Influenza is a highly contagious respiratory disease that causes high global morbidity and mortality each year. The dynamics of an influenza infection on the host metabolism, and how metabolism is altered in response to neuraminidase inhibitor drug therapy, is still in its infancy but of great importance. We aim to investigate the suitability of ferret nasal wash samples for metabolomics-based Cited by: 1.

In a series of landmark papers, Shope reported on the histopathologic changes in the respiratory tract of pigs, ferrets, and mice, describing changes compatible with those in human influenza virus infection, namely, desquamation of the ciliated epithelium of the tracheobronchial airways and peribronchial mononuclear cell inflammatory infiltrates (86, 88, 89).

Parainfluenza viruses (type 3 in particular) are significant causes of lower respiratory tract infection in adults when the virus is active in the community. In another 63 cases the histopathology of the epithelium of the respiratory tract was typical of influenza (StraubHers ); but no influenza-virus infection could be demonstrated, partly because no blood-serum from late stages was by: The pathology of respiratory syncytial virus (RSV) infection was evaluated 1 day after an outpatient diagnosis of RSV in a child who died in a motor vehicle accident.
We then identified 11 Cited by: Influenza viruses are significant human respiratory pathogens that cause both seasonal, endemic infections and periodic, unpredictable pandemics. The worst pandemic on record, inkilled approximately 50 million people worldwide. Human infections caused by H5N1 highly pathogenic avian influenza viruses have raised concern about the emergence of another pandemic.
The histopathology Cited by: Animal models of pandemic influenza indicate better replication within the lower respiratory tract and higher titer virus shedding as compared to seasonal influenza.
60 Histopathologic findings in these models mimic that of human disease and display features of necrotizing bronchiolitis, alveolar exudates, and antigen positive pneumocytes Cited by: 1.
Influenza virus binds to cell receptors via sialic acid (SA) linked glycoproteins. They recognize SA on host cells through their haemagglutinins (H). The distribution of SA on cell surfaces is one determinant of host tropism and understanding its expression on human cells and tissues is important for understanding influenza pathogenesis.
The objective of this study therefore was to Cited by: Emerging respiratory infections: The infectious disease pathology of SARS, MERS, pandemic influenza, and Legionella. Bradley BT(1), Bryan A(2).

Using a multidisciplinary approach, Human Respiratory Viral Infections is set at the level between the definitive reference work and an essential clinical ing recent advances in human respiratory viral research, the text builds on the basic sciences of epidemiology, virology, molecular biology, and immunology to cover clinical diagnosis, mechanism of pathogenesis.
William W. Johnston, Craig E. Elson, in Comprehensive Cytopathology (Third Edition), Fine-Needle Aspiration. The cytology of the respiratory tract has been revolutionized by a combination of two factors: evolution of highly sophisticated radiologic imaging techniques, making possible the precise visualization and localization of masses in the lungs, and reintroduction of a sampling.
Lower respiratory tract infections are more likely than upper respiratory tract infections to cause fever, dyspnea, or chest pain. Cough is often present in either upper or lower respiratory tract infections. People with influenza commonly have acute onset of fever, myalgia, headache, and cough.
Influenza is a viral infection of the respiratory tract. Infection is normally confined to the upper respiratory tract but certain viral strains have evolved the ability to infect the lower respiratory tract, including the alveoli, leading to inflammation and a disease pattern of diffuse alveolar by: Transplacental transmission of the H5N1 virus warrants careful investigation, since maternal infections with common human influenza virus are generally thought not to affect the fetus.
36 A sero-epidemiological study showed no evidence of transplacental transmission in pregnant women with human influenza infection. 37 Our placenta autopsy showed viral genomic sequences in cytotrophoblasts and resident macrophages; furthermore, the virus Cited by: The conducting portion is made up of: nasal cavities, nasopharynx, larynx, trachea, bronchii and bronchioles.
The trachea branches to give rise to two primary (main) then branch successively to give rise in turn to secondary and tertiary bronchii. These then branch to give rise to several orders of progressively smaller airways called bronchioles, the smallest of which are.
Studies of infectious diseases have been limited by the lack of models that recapitulate normal cellular physiology and pathology.
Developments in organotypic models have paved the road towards further studies of viral infections and host–virus interactions. For example, human intestinal organoids were efficiently used to study many viruses, such as rotavirus, norovirus, enterovi.
Sixteen years after the first reported human cases of avian influenza A(H5N1) virus [A(H5N1)] infection [1, 2], the avian influenza A(H7N9) virus [A(H7N9)] human infections appeared in Eastern China starting in February .A total of human A(H7N9) virus infection with a case-fatality rate of 32% were reported within 3 months after the announcement of the first case on 31 Cited by: Rationale: There are no reports of the systemic human pathology of the novel swine H1N1 influenza (S-OIV) infection.
