Valaciclovir, also spelled valacyclovir, is an antiviral medication used to treat outbreaks of herpes simplex or herpes zoster (shingles). [2] It is also used to prevent cytomegalovirus following a kidney transplant in high risk cases. [ 2 ]
Ensitrelvir has been studied for its potential use as post-exposure prophylaxis against COVID-19 in a phase 3 clinical trial. [3] [4] [5] Top-line results from this trial suggested that use of ensitrelvir as post-exposure prophylaxis may significantly reduce the risk of symptomatic COVID-19 infection in exposed household contacts compared to ...
This registry based, multi-center, multi-country data provide provisional support for the use of ECMO for COVID-19 associated acute hypoxemic respiratory failure. Given that this is a complex technology that can be resource intense, guidelines exist for the use of ECMO during the COVID-19 pandemic. [85] [86] [87]
The COVID-19 virus has not been detected in drinking water. [82] Conventional water treatment (filtration and disinfection) inactivates or removes the virus. [82] COVID-19 virus RNA is found in untreated wastewater, [82] [22] [83] [a] but there is no evidence of COVID-19 transmission through exposure to untreated wastewater or sewerage systems ...
The COVID‑19 vaccines are widely credited for their role in reducing the spread of COVID‑19 and reducing the severity and death caused by COVID‑19. Many countries implemented phased distribution plans that prioritized those at highest risk of complications, such as the elderly, and those at high risk of exposure and transmission, such as ...
SARS-CoV-2 is the seventh known coronavirus to infect people, after 229E, NL63, OC43, HKU1, MERS-CoV, and the original SARS-CoV. [105] Like the SARS-related coronavirus implicated in the 2003 SARS outbreak, SARS‑CoV‑2 is a member of the subgenus Sarbecovirus (beta-CoV lineage B). [106] [107] Coronaviruses undergo frequent recombination. [108]
“The dose is really dependent on the patient.” Until more research is done, the jury is still out on whether the general population would benefit from taking daily aspirin to prevent colon cancer.
Tolerable daily intake – Amount of a chemical contaminant that is safe; No-observed-adverse-effect level – Denotes the level of exposure of an organism without any observed adverse effects; Lowest-observed-adverse-effect level; Reference dose – Maximum acceptable oral dose of a toxic substance in the US
