The CDC continues to monitor the spread of COVID-19 and makes recommendations for wearing face face masks, both for those who are fully vaccinated as well as those who are not fully vaccinated.
The CDC also recommends that masks and physical distancing are required when going to the doctor’s office, hospitals or long-term care facilities, including all Johns Hopkins hospitals, care centers and offices.
Can wear a face mask prevent coronavirus from spreading?
Yes. Although being fully vaccinated greatly reduces your chance of catching or spreading the coronavirus, it doesn’t eliminate it entirely. If you are infected with the coronavirus and do not know it, a protective face mask is very good at keeping your respiratory droplets and particles from infecting others. If you haven’t yet received your COVID-19 vaccine, wearing a mask can also help prevent germs that come from another person’s respiratory droplets from getting into your nose and mouth.
Since the coronavirus can spread through droplets and particles released into the air by speaking, singing, coughing or sneezing, medical face masks are still a good idea in crowded indoor public places that contain a mixture of vaccinated and unvaccinated individuals.
Wearing a mask is still recommended in health care settings and other places where people around you may have risk factors for severe consequences of COVID-19. These include people over age 65 and those living with heart disease, diabetes, obesity, chronic lung disease, immunity problems or cancer.
Do I need to wear a face mask if I currently have COVID-19?
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 who has not been vaccinated yet or who has a weakened immune system. Stay away from others as much as possible and wear your disposable face mask around others until your doctor says it’s safe to discontinue wearing it.
Medical gauze is a type of thin medical fabric with a loose open weave used in wound care. Both gauze pads and gauze sponges are made of 100% cotton. They wick vertically to draw exudates out of wounds and are stronger than other types of dressings due to their longer fibers. Our gauze is offered in both sterile and non-sterile forms. For open wounds, it is recommended to use sterile gauze only.
Do I need to bandage a cut or scrape?
You do not need to bandage every cut and scrape. Some heal more quickly when left uncovered to stay dry. But if the cut is on a part of the body that might get dirty or rub against clothes, put on a bandage to protect it. Change the bandage every day or whenever it gets wet or dirty.
