We are surrounded by the news about COVID-19 and other viruses(病毒),but how much do you really know about them? Viruses that infect(感染) humans nearly always cause illness.Fortunately, just as we know a lot ab
COVID-19 is a respiratory disease. It can do a lot of damage to your respiratory tract, which includes your lungs. COVID can cause a range of breathing problems, from mild to critical. Older adults and people with other health conditions like heart disease, cancer, and diabetes may have ...
In contrast, serological tests look for specific antibodies that the body has produced to fight the virus. "If they detect those antibodies, [the test] gives a positive result," Adalja said. Singapore has developed an experimental antibody test for COVID-19, Science magazine reported, and Chin...
However, the makers of T-Detect (the onlyFDA-authorizedCOVID-19 TCR assay) have stated that they don’t know if being vaccinated would affect the test’s accuracy. One study found that people who were never sick with COVID-19 had a positive TCR assay resultafter being vaccinated. If you...
As the vaccines for COVID-19 continue to roll out and tens of millions more doses get into tens of millions more arms, I’m coming to the reluctant conclusion that I could, if I so desired, do nothing but blog about the antivaccine misinformation about these p...
While COVID-19 remains a concern, other pathogens pose significant risks. Although the pandemic's acute phase has lessened, healthcare-associated infections (HAIs) and secondary infections remain a threat, especially for those with compromised health or seeking medical treatment. ...
More than 10 days of positive tests are not a known risk factor for long Covid, but they do raise questions about where the virus could linger. Some viruses are known to hide in tissues that don't produce symptoms —like fat cellsorthe gut, for example — before reemerging on...
Overall, one clear strategy for improving the breadth of the immune response is to incorporate other proteins in addition to the S into vaccines. These should be proteins, or subunits of proteins, that are relatively conserved among SARS viruses, and potentially other types of coronaviruses. Much...
Further, an increase in the COVID-19 testing capacity to detect earlier coronavirus disease helps to reduce the spread of the virus, while its vaccines help to avoid contact with the coronavirus disease and improve the immune system by building antibodies that resist it. Thus, it is critical ...
Particularly in healthcare settings, the co-circulation of SARS-CoV-2, influenza and other respiratory viruses renders the use of rapid multi-target diagnostic tests necessary to guide infection control [11]. Paid sick leave may reduce ill presenteeism among HCP due to healthcare-associated ...
