A face shield is a piece of rigid, transparent plastic attached to a headband. The plastic piece covers the face, extending below the chin.

It is important to protect other people from getting COVID-19. Even if you are fully vaccinated and have a booster, wearing a mask provides an extra layer of protection, especially when you are around a person who may be at greater risk of COVID-19. Likewise, people who are at greater risk should strongly consider wearing a mask to help protect themselves.

N95 respirators offer a higher level of filtration than cloth, surgical or procedural masks. However, they are not necessary to protect people from viruses under normal circumstances. In order to be optimally effective, respirators must be fit-tested and worn properly, tightly fitted against the person’s face.

Although being fully vaccinated and/or boosted reduces your chance of catching or spreading the coronavirus, it does not eliminate it entirely. If you are infected with the coronavirus and do not know it, a mask keeps your respiratory droplets and particles from infecting others. Check the mask recommendations in your area to help decide whether you need to mask.

Like many medical facilities across the nation, our supply chain is feeling the effects of Hurricane Helene’s aftermath. Johns Hopkins Medicine currently has a sufficient sterile fluid supply to meet treatment, surgical and emergency needs. However, we have put proactive conservation measures into place to ensure normal operations, always with patient safety as our first priority. Examples of sterile fluids include intravenous (IV), irrigation and dialysis fluids. Learn more.

Johns Hopkins Medicine does not permit bandanas, gaiters or masks with exhalation valves to be worn by patients, staff members or visitors at our locations.

Yes. If you are actively infected with the coronavirus and cannot stay completely away from others in your home, droplets from your nose or mouth could infect another person. Stay away from others as much as possible and wear your mask around others until your doctor says it’s safe to discontinue wearing it.

N95 respirators, Dräger respirators and powered air purifying respirators (PAPRs) are used by medical professionals caring for patients with viral infections such as COVID-19, and when performing high-risk or aerosol-generating procedures.

In non-health care settings, multiple-layer fabric cloth masks are excellent barriers for containing respiratory droplets if they are worn consistently and properly, covering the nose and mouth.

Dentists and dental hygienists sometimes wear them when working close to patients’ mouths. Doctors, nurses and technologists might use face shields, together with face masks, when performing procedures that could propel blood or other substances into the air.

Sudden whiteouts don’t occur that often across all of Central New York, but definitely are more common north of Syracuse, due to lake effect snow.

Face masks provide protection against transmission of respiratory viruses. Additional steps to help the spread of respiratory viruses include hand washing, respiratory etiquette, and avoiding others when you are sick.

Support from the private sector, weather forecasting companies and the media has played a big role in the issuing of snow squall warnings.

You should not wear a face shield in place of a mask or wear clear shield-like face masks, which are different than face shields and have gaps around the face and therefore do not provide the same protection as wearing a mask.

The CDC provides an overview of various types of masks and respirators. In general, the most important things you can do are to choose a mask that fits well, and wear it consistently and properly when it is recommended or in situations that you are required to do so.

None of these three types of face coverings works as well as a proper face mask. A good mask has a double layer of washable, breathable fabric that helps keep the wearer from spreading potentially infected droplets into the air. A bandanna tied around the face does not work as well as a mask because it is open at the bottom. A gaiter (a tube of thin, stretchy knit fabric that can be worn around the neck and pulled up to cover the nose and mouth) is usually too thin to provide adequate protection. Likewise, masks with exhalation valves can allow droplets to escape into the air.

When you hear a buzz from your phone, if you are driving or about to head out, read it over as soon as you can and be sure to head the warnings so you don’t become a statistic on the highway.

According to Dave Nicosia, warning coordination meteorologist with the National Weather Service in Binghamton, a study done over a 20-year period showed that over 800 people were killed on the highways due to sudden snow squalls.

These are loose-fitting masks designed to cover the mouth and nose. Medical grade surgical or procedural masks provide excellent protection due to their filtration and fluid resistance. A simple “knot and tuck” technique can be used to improve the fit of rectangular surgical or procedural masks.
