Inhaled COVID-19 vaccine prevents disease and transmission in animals
(University of Iowa Health Care) In a new study assessing the potential of a single-dose, intranasal COVID-19 vaccine, a team from the University of Iowa and the University of Georgia found that the vaccine fully protects mice against lethal COVID-19 infection. The vaccine also blocks animal-to-animal transmission of the virus. (Source: EurekAlert! - Infectious and Emerging Diseases)

Has the COVID-19 pandemic lessened bullying at school?
(Wiley) Students reported far higher rates of bullying at school before the COVID-19 pandemic than during the pandemic across all forms of bullying--general, physical, verbal, and social--except for cyber bullying, where differences in rates were less pronounced. The findings come from a study published in Aggressive Behavior. (Source: EurekAlert! - Infectious and Emerging Diseases)

Study reveals how our immune system reacts to COVID-19 variants
(University of Sydney) Australian scientists researching how our immune system responds to COVID-19 have revealed that those infected by early variants in 2020 produced sustained antibodies, however, these antibodies are not as effective against contemporary variants of the virus.

Wolbachia and the paradox of growth regulation
(Instituto Gulbenkian de Ciencia) The findings, described in a study published in PLOS Genetics, expand on the complex role of a region of the genome of Wolbachia called Octomom, which is known to regulate its growth inside the host. And bring to light a paradox. If Octomom is deleted, Wolbachia grows uncontrolled inside the host. If amplified, with extra copies, it also grows uncontrolled. Both absence and excess lead to the same observable characteristic. (Source: EurekAlert! - Infectious and Emerging Diseases)

Mapping dengue hot spots pinpoints risk for Zika and chikungunya
(Emory Health Sciences) Data from nine cities in Mexico confirms that identifying dengue fever " hot spots " can provide a predictive map for future outbreaks of Zika and chikungunya. All three of these viral diseases are spread by the Aedes aegypti mosquito. (Source: EurekAlert! - Infectious and Emerging Diseases)

New study shows mathematical models helped reduce the spread of COVID-19
(University of Colorado Anschutz Medical Campus) Colorado researchers have published new findings in Emerging Infectious Diseases that take a first look at the use of SARS-CoV-2 mathematical modeling to inform early statewide policies enacted to reduce the spread of the Coronavirus pandemic in Colorado. Among other findings, the authors estimate that 97 percent of potential hospitalizations across the state in the early months of the pandemic were avoided as a result of social distancing and other transmission-reducing activities such as mask wearing and social isolation of symptomatic individuals.
