Are there face masks that should not be worn during the COVID-19 pandemic?
COVID-19Pregunta habitualVer respuesta completaAre there face masks that should not be worn during the COVID-19 pandemic?Face coverings limit the volume and travel distance of expiratory droplets dispersed when talking, breathing, and coughing. A face covering without vents or holes will also filter out particles containing the virus from inhaled and exhaled air, reducing the chances of infection. But, if the mask include an exhalation valve, a wearer that is infected (maybe without having noticed that, and asymptomatic) would transmit the virus outwards through it, despite any certification they can have.So the masks with exhalation valve are not for the infected wearers, and are not reliable to stop the pandemic in a large scale. Many countries and local jurisdictions encourage or mandate the use of face masks or cloth face coverings by members of the public to limit the spread of the virus.

What is the percentage of people who need to be immune against COVID-19 in order to achieve herd immunity?
COVID-19Pregunta habitualVer respuesta completaWhat is the percentage of people who need to be immune against COVID-19 in order to achieve herd immunity?We are still learning about immunity to COVID-19. Most people who are infected with COVID-19 develop an immune response within the first few weeks, but we don’t know how strong or lasting that immune response is, or how it differs for different people. There have also been reports of people infected with COVID-19 for a second time. Until we better understand COVID-19 immunity, it will not be possible to know how much of a population is immune and how long that immunity last for, let alone make future predictions. These challenges should preclude any plans that try to increase immunity within a population by allowing people to get infected.31 dic 2020

Can COVID-19 vaccines protect people against the SARS-CoV-2 virus when it has mutated?
COVID-19Pregunta habitualVer respuesta completaCan COVID-19 vaccines protect people against the SARS-CoV-2 virus when it has mutated?Vaccines against some viral diseases remain effective for many years and provide long-lasting protection. Others, such as the flu vaccine, need to be regularly updated to remain effective. This is because viruses constantly mutate when they circulate among people.Many SARS-CoV-2 mutations have no impact on vaccine effectiveness, but some are of concern due to a possible reduction in how well the existing vaccines will work. Scientists around the world are carefully monitoring mutations of SARS-CoV-2 virus to assess how well the currently available COVID-19 vaccines can protect people against them, and vaccine producers are exploring ways to update vaccines as necessary to improve protection as new variants are detected.Even with some COVID-19 vaccines’ reduced effectiveness against some of the new variants, COVID-19 vaccines are expected to offer some protection from severe forms of the disease.hace 6 días
