Why Does Covid-19 Cleaning Matters?
MERS-Covid-19 could thrive on plastic and metal surfaces for up to 48 hours.
It represents the universal environmental conditions in indoor spaces like a hospital ward, especially when at 20°C and 40% relative humidity. Also, bacterial culture from air and surfaces show that MERS [similar to COVID-19] could survive on surfaces even several days past contact with an infected patient.
The coronaviruses are sensitive to heat.
Ultraviolet light, non-ionic detergents, liquid solvents, and oxidizing agents also affect the virions adversely. Moreover, higher temperatures or increased levels of relative humidity also decrease viability. The most common incubation period of COVID-19 is between 2 and 14 days. However, there are also cases with incubation period of up to 27 days.
Do you really think face masks keep the uninfected safe! They don’t.
Except when used under high-exposure conditions, such as by health care workers, donning a face mask every day (especially cheap paper or cloth masks), doesn’t keep viruses from infecting you.
“Those who are not ill or on the frontlines of medicine may not benefit from wearing a mask,” said Dr. Michael Chang. He’s assistant professor of pediatrics at McGovern Medical School, and an infectious disease specialist with UT Physicians.
“Wearing a mask when you are not sick essentially gives you a false sense of confidence that you don’t need to wash your hands as often, or not touch your face as much,” Chang explained in an UT Health news release. “And, because masks can be uncomfortable, you may actually touch your face more. In addition, contamination can occur when masks are taken off and put back on.”
Also, when lay people snap up face masks needed to protect health care workers, that puts everyone at risk. Every nurse or doctor infected means fewer people to care for the very ill.
Late last month, U.S. Surgeon General Dr. Jerome Adams acknowledged the situation, tweeting ” “Seriously people — STOP BUYING MASKS!”
One exception to the rule: If you develop symptoms of COVID-19, such as fever and coughing, wearing a face mask could help lower the transmission of infectious droplets in air, experts say.
Hand-washing only kills coronavirus if water is hot- Not Correct!.
Washing your hands with hot water isn’t any more effective than with cold water. Frequent hand-washing with soap and water is recommended as one of the best ways to limit the spread of the coronavirus, but the temperature of the water doesn’t matter.
When “washing hands with soap and water, it’s really the mechanical scrubbing action that’s cleaning your hands,” Chang explained. “You can use warm or cold water. You have to be sure you wash/scrub long enough (at least 20 seconds) and completely dry your hands.”
Researchers at Yale say the coronavirus shows up in stool days before a person shows symptoms.
Researchers say they think sewage can predict COVID-19 outbreaks for two months, they have tested sludge at New Haven’s wastewater treatment plant. Yale Engineering and a state lab found coronavirus levels in sewage nearly
match the official testing numbers but they show up a week earlier. “There’s a delay of about a week from you getting sick to becoming tested, and then that data being reported,” said Dr. Jordan Peccia, of Yale School of Engineering.
That extra week can give a critical early warning to a coming spike in infections.
“This is something that could be used as a surveillance method, to be able to monitor the amount of activity that’s going on in the community without having to test everybody,” said Dr. Doug Brackney, of Connecticut Agricultural Experiment Station. For now, the testing is just in New Haven, but it could be expanded across the state. Connecticut is on the leading edge of this research. One study found about half of COVID-19 infections show up in human feces. It is still not clear if the virus can be transmitted that way.

COVID-19 Cleaning in the washrooms of your offices
Closing the toilet lid is highly recommended amid the coronavirus outbreak, according to a report, as a group of researchers have found that the bug can spread through fecal matter that escapes from the bowl during a flush.
The disease caused by the coronavirus, which scientists had already warned can be spread from fecal-oral transmission, can also be transmitted via “aerosolized feces,” according to Forbes, citing a study published by the Association for Professionals in Infection Control and Epidemiology.
Aerosolized feces can be propelled into the air through what’s called a toilet plume — the spread of aerosols, sometimes containing infectious fecal matter, caused by a flush.
Nasal vs Fecal Covid-19 test results…not the same!
Researchers found that testing people for SARS-CoV-2 — the virus that causes COVID-19 — too early in the course of infection is likely to result in a false negative test, even though they may eventually test positive for the virus.
What is the risk of coronavirus to pregnant women and their unborn babies?
We do not currently know if pregnant women have a greater chance of getting sick from COVID-19 than the general public. With viruses from the same family as COVID-19, and other viral respiratory infections, such as influenza, pregnant women have had a higher risk of developing severe illness.
The main source for MERS-CoV was dromedary camels.
These virus animal reservoirs served as the intermediate host source for human infections of the same strain. For MERS, there have been no documented human-to-human transmission or community outbreaks apart from close contacts. [COVID-19 has been found in minks, dogs, and a host of other mammals so far, meaning the transferability of COVID-19 is yet to be determined).
Coronavirus in saliva could travel more than 5m in a ‘slight breeze’ (k)
Staying two metres apart may not be far enough to stop outdoor coronavirus transmission, a study has suggested.
Research from the American Institute of Physics has found saliva droplets can travel more than five metres in five seconds if there a slight breeze of around 4kph (2.5mph). Professor Dimitris Drikakis, one of the authors of the study published in the journal Physics of Fluids, said shorter adults and children could be at greater risk if they are near the trajectory of the droplets. He added: “The droplet cloud will affect both adults and children of different heights.”
