COVID-19: What You Need to Know About Antibody Testing
As the number of COVID-19 cases in the U.S. surpasses 800,000, many Americans want to know if recovered patients have immunity to the novel coronavirus.
The answer could come from an antibody test.
Antibody tests measure the number of antibodies – proteins made by plasma cells – in the blood. The body's immune system uses antibodies to neutralize pathogens such as viruses and bacteria.
While these tests are commonly used to tell if someone is immune to diseases such as measles or chickenpox, they're not yet widely available for COVID-19. But it's not clear what the results would mean, said infectious disease specialist Rekha Murthy, MD, vice president of Medical Affairs and associate chief medical officer at Cedars-Sinai.
"We have the expectation that a positive antibody test can be associated with protection against future infections. But since this pandemic has evolved so quickly,

Radiation Effective in Sterilizing Personal Protective Equipment Except For Respiratory Masks
Radiation is an effective and established tool to sterilize personal protective equipment (PPE) that is in high demand during the COVID-19 pandemic, except for respiratory face masks as it weakens their filters, the International Atomic Energy Agency (IAEA) said.
While radiation is not recommended to sanitize certain types of used masks for hospital staff, the IAEA encourages Member States to continue to irradiate other PPE for sterilization prior to their use, including surgical masks and gloves.
Upon request from several countries, the IAEA reviewed findings from five institutions that tested the use of ionizing radiation – gamma and electron beams – to sterilize used respiratory masks, such as models N95 and FFP2 commonly worn by medical personnel. As numbers of COVID-19 infections increase, shortages in protective equipment for staff on the frontline of the pandemic continue to pos

Unique System for Using UVC Light to Sterilize Masks in Bulk Developed at Rensselaer
New device for making masks reusable in fight against COVID-19 being tested at Mount Sinai
The shortage of critical personal protective equipment (PPE) has been a persistent problem for medical and other front-line workers as they battle the COVID-19 pandemic at close range day after day. A team of researchers at Rensselaer Polytechnic Institute has developed a potential solution: a machine that uses ultraviolet (UVC) light to sterilize thousands of protective masks each day, rendering them safe for reuse.
“At Rensselaer, we are focused on solving global challenges, and the COVID-19 pandemic is certainly among the most significant of these in our lifetimes,” said Rensselaer President Shirley Ann Jackson. “Our interdisciplinary approach, combined with the passion and ingenuity of our researchers, enables us to contribute solutions in this crisis that will continue to be helpful even a

New American Academy of Dermatology Survey Finds Most Americans Know Sun Protection is Important, Yet Many Aren't Protecting Themselves
In recognition of Skin Cancer Awareness Month in May, dermatologists remind the public to #PracticeSafeSun to reduce their risk of skin cancer
As more Americans head outdoors for warmer weather and fresh air amid “shelter-in-place” measures, dermatologists from the American Academy of Dermatology have an important reminder: practice safe sun. Skin cancer is one of the most preventable types of cancer, but new data from the AAD shows that many Americans aren’t taking the necessary steps to protect themselves.
According to a recent AAD survey, 76% of Americans agree that sun protection is an important healthy habit, yet only 41% report regularly protecting themselves outdoors — increasing their risk for skin cancer. While exposure to the sun’s harmful ultraviolet (UV) rays is the most preventable risk factor for skin cancer, the survey also revealed that 28% of Americans admit they rarel
