"Bromine" Poem by Michael Walkerjohn

"Can bromine kill you? "

"Bromine is corrosive to human tissue
in a liquid state and its vapors irritate eyes
and throat. Bromine vapors are very toxic with inhalation.
Humans can absorb organic bromines through the skin, with
food and during breathing. Organic bromines are widely
used as sprays to kill insects and other unwanted pests."

"An interpretable mortality prediction model for COVID-19 patients"

"… three biomarkers that predict the mortality of individual patients
more than 10 days in advance with more than 90% accuracy:
lactic dehydrogenase (LDH) , lymphocyte and high-sensitivity
C-reactive protein (hs-CRP) . In particular, relatively high levels
of LDH alone seem to play a crucial role in distinguishing the vast
majority of cases that require immediate medical attention."

co·mor·bid·i·ty
/ˌkōmôrˈbidədē/
noun
plural noun: comorbidities
"… the simultaneous presence of two chronic diseases or conditions
in a patient."

"… Nearly All NYC-Area COVID-19 Hospitalizations Had Comorbidities
The most common preexisting conditions among the patients
were diabetes, obesity, and hypertension."

"… Droplets from Speech Can Float in Air for Eight Minutes:
Study
The experiments did not involve SARS-CoV-2, but researchers say
the results support precautions to avoid possibly
spreading COVID-19 by talking."

"Recognition of aerosol transmission of infectious agents: a commentary"
Published: 31 January 2019

Abstract
"Although short-range large-droplet transmission is possible
for most respiratory infectious agents, deciding on whether the
same agent is also airborne has a potentially huge impact on the
types (and costs)of infection control interventions that are required."

"The concept and definition of aerosols is also discussed, as is the
concept of large droplet transmission, and airborne transmission which
is meant by most authors to be synonymous with aerosol transmission
although some use the term to mean either large droplet or aerosol
transmission."

"However, these terms are often used confusingly when discussing
specific infection control interventions for individual pathogens
that are accepted to be mostly transmitted by the airborne (aerosol)
route. It is therefore important to clarify such terminology, where
a particular intervention, like the type of personal protective
equipment (PPE)to be used, is deemed adequate to intervene for
this potential mode of transmission, i.e. at an N95 rather than
surgical mask level requirement."

"With this in mind, this review considers the commonly used term
of ‘aerosol transmission' in the context of some infectious agents
that are well-recognized to be transmissible via the airborne route.
It also discusses other agents, like influenza virus, where the
potential for airborne transmission is much more dependent on
various host, viral and environmental factors, and where its
potential for aerosol transmission may be underestimated."
