Tracking COVID-19 trends in hard-hit states
Currently, there are over 10 million confirmed cases and more than 240,000 casualties attributed to COVID-19 in the U.S. Researchers at Louisiana State University have applied computational models to investigate infection rates in relation to social distancing measures. Their paper, Effect of mitigation measures on the spreading of COVID-19 in hard-hit states in the US, was recently published in PLOS ONE. (2020-11-24)

New insight into the effect of hydroxychloroquine undermines its use in COVID-19
Researchers at Radboud university medical center have discovered an as yet unknown effect of hydroxychloroquine. It inhibits the action of a type of white blood cells important in the first line of defense against infections. Based on this research, hydroxychloroquine is unlikely to be beneficial in clearing viral infections including the new coronavirus SARS-CoV-2, they write in their publication in Cell Reports Medicine.

Understanding lung infections in patients with cystic fibrosis
For young people with cystic fibrosis, lung infection with Staphylococcus aureus, MRSA, is common and is treated with antibiotics in the hope that this will prevent a decline in lung function. However there has recently been debate over the role S. aureus plays in CF lung disease. Researchers from the University of Warwick have used a new model of CF lungs which could be used to make better decisions about future use of antibiotics. (2020-11-19)

Time to rethink predicting pandemic infection rates?
Doubling times and exponential growth go hand in hand, so it became clear to Joseph Lee McCauley, when watching the COVID-19 rates, that modeling based on past infections is impossible, because the rate changes unforeseeably from day to day due to social distancing and lockdown efforts. In AIP Advances, McCauley explains how he combined math with a statistical ensemble to understand how macroscopic exponential growth with different daily rates arise from person-to-person disease infection. (2020-11-17)

Immunological memory after cured Sars-CoV-2 infection
After recovery from SARS-CoV-2 infection, immune cells are formed which remain in the body and could mediate a rapid immune response in case of re-infection. The Freiburg study was published in the online edition of Nature Medicine on November 12, 2020 and gives hope for vaccine development. (2020-11-17)

Why are some COVID-19 infected people asymptomatic?
Immune cells in the lungs are important for the immune system's recognition and fight against viruses. However, the virus that produces COVID-19 is not recognised by these cells, as the virus may hide its genomic material, and as a result the cells' immune system against the virus is not activated. This may help explain why some people with COVID-19 are asymptomatic in the early stages of the disease. (2020-10-28)

In study of 30,000 mild-to-moderate COVID-19 patients, antibody responses can persist for five months
Researchers who studied antibody responses in 30,000 patients with mild-to-moderate COVID-19 report that the patients' antibodies were relatively stable for at least five months. (2020-10-28)

Random effects key to containing epidemics
To control an epidemic, authorities will often impose varying degrees of lockdown. In the journal Chaos, scientists have discovered, using mathematics and computer simulations, why dividing a large population into multiple subpopulations that do not intermix can help contain outbreaks without imposing contact restrictions within those local communities. When infection numbers are high, random effects can be ignored. But subdividing a population can create communities so small that the random effects matter. (2020-10-27)
