From a public health standpoint, it is useful to define stages of an infectious disease with respect to both clinical disease and potential for transmission (Figure 3). With respect to disease, the incubation period is defined as the time from exposure to an infectious agent until the time of...
With improved public health measures including sanitation processes and sewage treatments, as well as improved healthcare services and the introduction of antibiotics and vaccination protocols, the prevalence of infectious diseases appeared to be declining. As a result, health care professionals and ...
First, it is possible that the changes in anti-nucleocapsid IgG antibodies, which are sometimes interpreted as evidence of re-exposure to SARS-CoV-2 [20], may not necessarily be caused by re-infection but by other factors including infection with human coronaviruses of the common cold. More...

Contaminated water or raw sewage may mix with soil in areas where the rainfall is usually heavy, such as in the tropics. The protozoa that cause malaria and the mosquitoes that act as carriers thrive in such conditions; the resulting increased propagation of both the protozoa and the mosquitoes...

Phages isolated from sewage were able to lyse the intestinal cytolytic E. faecalis strain and alleviated alcohol-induced liver damage. 3.4. Phages and Intestinal Inflammation Bacterial components and phage DNA, released from the lysed bacteria, are the main ligands that trigger intestinal immunity ...
Samples are taken from index case patients (e.g., blood, feces, throat swabs) as well as from possible reservoirs (e.g., food, water, sewage, environment). A working hypothesis is established based on the first findings, taking into account all plausible explanations. The epidemic pattern ...
