How
fast can coronavirus spread via hospital surfaces?
New research aims to mimic how
SARS-CoV-2, a Covid-19 virus, can spread to complete hospital settings. For
safety, the researchers did not use the SARS-CoV2 virus but re-activated a
portion of the DNA from the plant, which can infect humans, and placed it in
milliliters of water where copies of SARS-CoV2 were stored in viral respiratory
samples.
Result: The DNA virus left in a hospital bed train was found in almost
half of all sites used in the ward within 10 hours and continued for at least
five days. This study, conducted by University College London and Great Ormond
Street Hospital (GOSH), has been published as a book in the Journal of Hospital
Infection. Investigators put the DNA-containing water at the train station in a
separate room - that is, a room for high-risk or infected patients - and placed
the samples in 44 locations in the hospital yard over the next five days.
They
found that within 10 hours, distributed genetic material had spread to 41% of
the sample sites across the hospital ward, from thousands of beds to arms held
in the waiting room to book toys and books in the play area. This increased to
59% in three days, to 41% on the fifth day. The highest proportion of sites
that are considered surrogate are immediately from the bed area - including the
ear by room for several other beds - and clinical areas such as treatment
rooms.
On the third day, 86% of the sample sites at the clinic were tested
positive, and by the fourth day, 60% of the sample sites at the clinic were
diagnosed. Sars-CoV-2 is likely to be distributed inside body fluids such as
sputum droplets, and research has used DNA virus in water. Too much sticky
fluid such as mucus can spread easily. One reason for the study is that,
although it shows how quickly the virus can spread when left on the surface, it
cannot detect the potential for a person to become infected with the virus.
Our
research demonstrates the significant role that plays a role in spreading the
virus and how important it is to adhere to hygiene and hand hygiene. A person
with SARS-CoV2, however, will spread the virus to more than one site, with
coughing, sneezing and facial scratches. ”
New research has found that
patients with high blood pressure have twice the risk of COVID-19 mortality
compared to patients without high blood pressure. Their search was published in
the European Heart Journal on Friday. Researchers in China and Ireland analyzed
data from more than 2,800 Covid19 patients admitted between February 5 and
March 15 at Wuhan's HuoShen Shan Hospital, which specializes in Covid patients.
Of these patients, 29.5% (850) had a medical history of high blood pressure
(hypertension).
Researchers found that 34 of the 85 hypertensive (4%) patients
with Covid-19 achieved a comparison with 22 of the 2,027 patients with
unhealthy hypertension (1.1%) - an increase of 2.12 after adjusting for side
effects, such as age, sex and other health conditions. In addition, the study
found that patients with high blood pressure who did not take control
medication were at higher risk of Covid-19 mortality.
Among hypertensive
patients who were not taking medication for this condition, 11 out of 140 (7.9%)
died of coronavirus compared with 23 of 710 (3.2%) of those taking medication
a2.17-fold after adjusting for confounding factors. In a meta-analysis,
researchers included data from HuoShen Wan patients with data from nearly 2,300
patients in three other studies to investigate mortality rates in patients
treated with drugs to control blood pressure levels.
Specifically, they
compared between patients who were treated with a drug group called RAAS
inhibitors, and those who were treated with other drugs. They found a lower
risk of death among 183 patients treated with RAAS inhibitors than 527 patients
treated with other drugs. However, investigators say that this effect should be
treated with caution as the number of patients in this analysis is small and therefore
likely due to the risk. Investigators are led by Professors Fei Li and Ling Tao
from the Beijing hospital. As this was a study looking at data from hospital
observations, researchers said it was too early to make clinical
recommendations based on these results, and that results from randomized
controlled clinical trials are needed.
