What’s a Respiratory Droplet and Why Does It Matter?

Different viruses are spread in different ways. The main way that SARS-CoV-2, the virus that causes COVID-19, spreads between people is by respiratory droplets. “In this case, a ‘droplet’ doesn’t just mean water that you can see, like big raindrops or splashes in the sink or a pool,” 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. “These droplets we’re talking about are actually really tiny, and where they come from may surprise you.” Where Do Respiratory Droplets Come From? You might think that when you breathe out, all that comes out is air. But our breath contains water too, in the form of respiratory droplets. ...

Why Do Cleaning and Disinfection Matter in Healthcare?

Cleaning removes dust, dirt, and germs from surfaces and objects. Disinfection makes sure that as many germs as possible are destroyed or killed. Cleaning and disinfection are both important infection control actions in hospitals and other healthcare settings because they keep germs away from people and help keep germs from spreading. Seems like common sense, right? “Even though it’s common sense, it’s important to think through all the reasons why we’re so careful about keeping an environment clean,” said Dr. Abigail Carlson, an infectious diseases physician with the CDC, as part of CDC Project Firstline’s Inside Infection Control video series. The Importance of Cleaning and Disinfection: The Immune System When we are healthy, our bodies have many built-in ways to ...

Contact Time: What is It and How Does it Impact Infection Control?

We know germs can cause illnesses. We also know that frontline healthcare workers can take action to protect themselves, their colleagues, and their patients from infectious disease threats. Cleaning and disinfecting are two of these important actions for infection control. A fundamental part of this process is “contact time.” This is the amount of time a disinfectant must sit on a surface, without being wiped away or disturbed. Contact time allows the disinfectant to do its job: Killing germs. “There are a lot of germs in healthcare. That's no surprise to any of us,” said Dr. Abigail Carlson, an infectious diseases physician with the U.S. Centers for Disease Control and Prevention (CDC), as part of CDC Project Firstline’s Inside Infection Control video ...

COVID-19 continues to have a large impact on Latinos and other communities of color, particularly when it comes to cases and deaths. However, the toll extends beyond the physical impacts of the virus. Racial and ethnic minority populations are more likely to experience COVID-19–related discrimination than their white counterparts, according to a new study from the National Institute on Minority Health and Health Disparities (NIMHD). Learn what the study found on COVID-19–related discrimination, the impact of discrimination on health, and what we do to improve the situation for Latinos and others of color. What Did the NIMHD Study Find on COVID-19-Related Racial/Ethnic Discrimination? This is the largest study to date on discrimination related to COVID-19. Dr. Paula D. ...

How Does Infection Control Work on COVID-19 Variants Like Omicron?

COVID-19 has changed a lot of practices for frontline healthcare workers, from screening employees and patients at entrances to wearing masks all the time. The pandemic has also taught us more about variants. As a virus like COVID-19 spreads, it can mutate and change — these changes are known as variants, such as the Delta and Omicron variants. New variants of viruses are common. Fortunately, the strategies healthcare workers use for infection control are designed to work regardless of the variant, said Dr. Abigail Carlson, an Infectious Diseases physician with the U.S. Centers for Disease Control and Prevention (CDC). “The tools that we use for infection control work. And the way they work for COVID-19 hasn't changed,” Carlson said. “It's all the more important to ...

María Elena Bottazzi: The Latina Scientist Who Helped Create a COVID-19 Vaccine


Maria bottazzi

When María Elena Bottazzi left Honduras, she never expected to one day be nominated for a Nobel Peace Prize. Bottazzi is a microbiologist at the Texas’s Children’s Hospital Center for Vaccine Development at Baylor College of Medicine in Houston, Tex. She, along with Dr. Peter Hotez of Baylor Medicine, created the Corbevax vaccine for COVID-19. They wanted to create a unique vaccine that was patent-free and cheaper to produce than the vaccines already on the market. “Peter and I aspire to benefit people, which is why we created a vaccine for the poorest communities in the world. The team that we have built shares the same interest in promoting public health and, obviously, learning at the same time,” Bottazzi said, according to NBC Latino. Bottazzi and Hotez were ...

Study: Peer Modeling with Psychological Inoculation Can Promote COVID-19 Vaccinations


covid-19 vaccines peer modeling with psychological inoculation study2

COVID-19 vaccination is often deterred by misinformation, from conspiracy theories to exaggerated side effects on social media. Vaccine misinformation is potent among Latinos due to lack of reliable information that is culturally relevant or in Spanish, along with little government outreach. That is why UT Health San Antonio researchers studied a new type of advertisement on Facebook to push people to get vaccinated. They used video testimonial ads of Latino peer role models, like Rosa Herrera, who tout the benefits of the COVID-19 vaccine, while providing psychological inoculation by acknowledging misinformation, rejecting it, and receiving the vaccine. Compared to generic vaccine promotion ads from the CDC, the Latino peer model ads yielded a significantly higher rate of ...
