After a person recovers, it is unclear how long they remain contagious. Genetic material of the virus may be detectable up to two weeks after infection, but that "does not necessarily mean that infectious virus is present," according to the CDC. Is there an average length for COVID-19 ill...
There are many parallels between Covid-19 and HIV/Aids. There are both highly infectious novel viruses which reached pandemic proportions very quickly, and, at this point, there is no vaccine against either of them. But what happens when the two viruses collide? Unlike all the other regions ...
It has not just been the examples cited in the above document that concern me but the widespread lack of education among public health physicians regarding aerosol dispersion of infectious respiratory diseases, asymptomatic infection, potential for spread via fomites, selection-use-limitations on PPE, ...

(Fig.1) by which systemic infectious agents induce neurodegeneration, occurring exclusively in vulnerable brain areas with underlying AD pathology. The Amyloid deposition may not cause neurodegeneration by itself, but rather result in brain susceptibility to the neurotoxic effect of infectious agents. ...
But we're not sure whether people are infectious when they have recovered but the virus can still be detected in their bodies. One study from Hong Kong found the virus could be detected for20 days or longerafter the initial onset of symptoms in one-third of patients tested. ...
The Amyloid deposition may not cause neurodegeneration by itself, but rather result in brain susceptibility to the neurotoxic effect of infectious agents. This suggests a “hit and run” mechanism, where the infectious agent-derived PAMPs -induced neurodegeneration may be masqueraded, as it occurs ...
Until younger children are eligible to get vaccinated, “we’ve got to do our best to protect them,” Dr. Stephen Parodi, national infectious disease leader for Kaiser Permanente,told CNN in November. “For the youngest children that we have, we still got to take those protective measures w...
Table 4. Association between concern about the spread of COVID-19 and the age group of the participants. According to Table 5, concern about the spread of COVID-19 was not significantly associated with the educational level of teachers. In this regard, it is observed that the predominant ...
In the base case (25 percent more infectious; 25 percent greater immune evasion; 25 percent less severe disease), the COVID-19-related hospitalization rate in the United States could peak significantly higher in the next six months than in the past six. In the pessimistic scenarios, the pea...
