The longer a susceptible person stays in such a space, the greater chance of transmission. Airborne transmission is complex, and hard to demonstrate unequivocally [20] but the Wells-Riley model can be used to make simple estimates of infection probability. [21] Some airborne diseases can affect non-humans.
Primarily white blood cells, mainly mononuclear cells, generate the inflammation. [60] As well as damaging the lungs, many viruses simultaneously affect other organs and thus disrupt other body functions. Viruses also make the body more susceptible to bacterial infections; in this way, bacterial pneumonia can occur at the same time as viral ...
The neutrophils, bacteria, and fluid leaked from surrounding blood vessels fill the alveoli and result in impaired oxygen transportation. Bacteria can travel from the lung into the blood stream ( bacteremia ) and can result in serious illness such as sepsis and eventually septic shock , in which there is low blood pressure leading to damage in ...
An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...
The low blood pressure seen in those with sepsis is the result of various processes, including excessive production of chemicals that dilate blood vessels such as nitric oxide, a deficiency of chemicals that constrict blood vessels such as vasopressin, and activation of ATP-sensitive potassium channels.

Bloodstream infections (BSIs) are infections of blood caused by blood-borne pathogens. [1] The detection of microbes in the blood (most commonly accomplished by blood cultures [2]) is always abnormal. A bloodstream infection is different from sepsis, which is characterized by severe inflammatory or immune responses of the host organism to ...
A routine chest X-ray is not always necessary for people who have symptoms of a lower respiratory tract infection. [4] Influenza affects both the upper and lower respiratory tracts. [citation needed] Antibiotics are the first line treatment for pneumonia; however, they are neither effective nor indicated for parasitic or viral infections. Acute ...
It is estimated that DVT affects one in 5,000 travellers on long flights. [9] [10] Risk increases with exposure to more flights within a short time frame and with increasing duration of flights. [10] According to a health expert in Canada, even though the risk of a blood clot is low, given the number of people who fly, it is a public health ...
