The main way that SARS-CoV-2, the virus that causes COVID-19, spreads between people is by respiratory droplets. These are the tiny droplets of water that come out when you talk, cough, and breathe out and that other people can breathe in. The most common way we get infected with COVID-19 is when we breathe in the virus. Although less common, we can also get infected when we touch a surface that has virus on it. “When you touch something that has live virus on it and then you touch your face without cleaning your hands first, you can get virus into your eyes, your nose, and your mouth,” said Dr. Abigail Carlson, an infectious diseases physician with the Centers for Disease Control & Prevention (CDC), as part of CDC Project Firstline’s Inside Infection Control video ...
U.S. Latinos continue to deal with a heavy burden of COVID-19. Even if they don’t feel sick, a Latino or any person who is infected with SARS-CoV-2, the virus that causes COVID-19, can spread the virus to others. But how does that spread happen?
How Viruses Spread
Even when you have a mild infection, there is virus in your nose, throat, and lungs. Virus particles can spread through respiratory droplets that come out when you talk, breathe, cough, or blow air out of your nose or mouth. When you release respiratory droplets, they can land on someone’s eyes, nose, or mouth, or someone can breathe them into their respiratory tract. If this happens, the virus in the droplets can infect them. Respiratory droplets can also fall on surfaces. If someone touches that surface ...
SARS-CoV-2 is the official scientific name of the virus that causes the disease COVID-19. When we get infected with SARS-CoV-2, we can get sick with COVID-19, which stands for Coronavirus Disease 2019. When you are sick with COVID-19, you may have fever, chills, cough, difficulty breathing, and other symptoms.
How We Use the Terms SARS-CoV-2 and COVID-19
COVID-19 is the term we most often use to talk about the pandemic. We use SARS-CoV-2 when we talk about the virus and what it does in the body to make people sick. “In healthcare, you may see SARS-CoV-2 on test results, which are often recorded by the official name of the virus,” said Dr. Abigail Carlson, an infectious diseases physician with the Centers for Disease Control & Prevention (CDC), as part of CDC ...
About 24% of teachers say they have been told to limit classroom conversations about political and social issues, such as racism, according to a recent survey. The nationally representative survey was taken by over 3,800 teachers and principals by the RAND Corporation in January of 2022 to gauge educator’s views on politicized topics in schooling. In the survey, 54% of teachers and principals urged no legal limits on classroom conversations about racism, sexism, and other topics that some people disagree about. “In a time when simply carrying out the essential functions of their jobs is a herculean task, educators have been faced with the additional challenge of addressing contentious, politicized topics in their schools and classrooms,” according to the report. How does ...
Respirators are a common type of personal protective equipment (PPE) – but not the only one. Gowns, gloves, goggles, and face shields are other kinds of PPE that Latino and all frontline healthcare workers use to help the spread of germs and viruses, including the virus that causes COVID-19.
Gowns
In healthcare, gowns are worn over your work clothes to reduce transmission of germs. They make it easier to remove germs and body fluids that might get on you while you work. “Germs that get on your clothes can spread to you. But they can also spread to other surfaces and other people,” said Dr. Abigail Carlson, an infectious diseases physician with the Centers for Disease Control & Prevention (CDC), as part of CDC Project Firstline’s Inside Infection Control video series. ...
COVID-19 is not over, especially for Latinos. To help people stay vigilant in stopping the spread, the CDC recently published an updated Summary of Guidance for Minimizing the Impact of COVID-19 on Individual Persons, Communities, and Health Care Systems. “To prevent medically significant COVID-19 illness and death, persons must understand their risk, take steps to protect themselves and others with vaccines, therapeutics, and nonpharmaceutical interventions when needed, receive testing and wear masks when exposed, receive testing if symptomatic, and isolate for [greater than or equal to] 5 days if infected,” the CDC reported on Aug. 11, 2022. Vaccines and Therapeutics to Reduce Medically Significant Illness The CDC recommends a strategic approach to minimize the impact ...
Infection control saves lives, and every frontline healthcare worker plays a critical role. To better support healthcare workers to prevent infections in health care, it is essential to equip them with the infection control knowledge they need and deserve to protect themselves and their patients from infectious disease threats, like COVID-19. This is why CDC launched Project Firstline, an infection control training and education collaborative designed with healthcare workers, for healthcare workers. Project Firstline intends to provide equity of understanding for all: nurses, certified nursing assistants, environmental service technicians, doctors, allied health professionals, and administrative/intake staff. The innovative content is designed so that regardless of previous ...
We all know that some viruses make us sick, like norovirus, which causes vomiting and diarrhea; rhinovirus, which causes the common cold; and SARS-CoV-2, the virus that causes COVID-19. But how do these viruses make us sick? What happens when a virus gets into the body? Our bodies are made up of billions of microscopic building blocks, called cells. On the outside of our cells, there are tiny parts that stick out. Those tiny parts are made of proteins that act like a lock on a door. If you have the right “key” for the “lock,” then you can get into the cell. Some virus cells can have tiny parts that stick out on their outsides, too. Those tiny parts can work like a “false key” that can fit the “lock” to some types of our bodies’ cells. It’s not an exact ...
Ventilation is the movement of air in and out of spaces. Good ventilation can help remove things from the air that we don’t want to breathe in, such as chemicals and dust – and small virus particles released by someone who is infected with a respiratory virus, like SARS-CoV-2. “The fewer virus particles in the air, the less likely you are to breathe them in, or that the virus particles will land on your eyes or a surface that you might touch,” said Dr. Abigail Carlson, an infectious diseases physician with the Centers for Disease Control & Prevention (CDC), as part of CDC Project Firstline’s Inside Infection Control video series.
The Importance of Air Changes
Good ventilation involves air changes, which means that the air in a room is replaced with new or filtered ...
