What is not known, however, is the mechanism of infectious cough brought on by rhinovirus. Such knowledge could help lessen the financial burden (around $40 billion in the United States) of the common cold and its accompanying cough. The common cold itself creates self-limited discomfort, but...
Those of which hold most promise are physical disruption of the epithelial lining, excess mucus production and an inflammatory response to rhinovirus infection which may be excessive. And finally, neuronal modulation, the most convincing hypothesis, is thought to potentiate cough long after the ...
Just because science has come a long way in addressing major illnesses doesn't mean that large-scale breakouts can't happen anymore. The 2020coronavirus disease(COVID-19) pandemic has left health care experts and world leaders grappling with what the best course of action is to combat the vi...
Virusesare much smaller than bacteria and are not considered living organisms. They are infectious agents with only a protein shell and a strand of RNA or DNA, depending on the type of virus. They do not reproduce on their own—like bacteria do. Instead, viruses need a host cell to do t...
While the N-terminus of the VP4 protein in other picornaviruses is known to be transiently exposed to the outside of the capsid during a process called virus breathing [48,49,50], it is not clear whether the C-terminus of the VP4 protein is exposed to the antibodies. Finally, a ...
Once virus is internalized, the cell undergoes an eclipse phase (E) during which infected cells do not yet produce the virus. The cells then transition to the infectious phase (I) at a k rate per day. Productively infected cells are cleared at a 𝛿δ rate per day. The virus is ...
A cold should get better in about a week—that goes for infants, children, and adults.1The virus can involve the sinuses and produce nasal congestion, sinus pressure, and clear mucus drainage for as long as 10 days. At that point, a viral sinus infection should begin to improve on its ...
Respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract disease in young children and elderly people. Although the virus was isolated in 1955, an effective RSV vaccine has not been developed, and the only licensed intervention is
Rhinovirus is the most common cause of colds among children and has continued to circulate in high numbers in recent years, says Murray. Less often, it can lead to hospitalizations. Another common cause of respiratory illness among kids are human parainfluenza viruses, Murray adds. In addition ...
What causes the common cold, and how is it spread? The common cold refers to a group of symptoms caused by viruses. Rhinoviruses cause the most cases of the common cold, and more than 200 different viruses have been identified that cause cold symptoms. ...
