Weekly Updates Research, Findings, Transmission and Global Statistics
…to help in understanding and acting responsibly in the community and to help protect yourself and those around you.
Live and expansive statistics and facts about the coronavirus and covid 19 pandemic, its process and information to help decide the best behaviour and practise in responding, and to protect yourself and others in the wider community, there’s no one to blame but ourselves if it gets worse, the median age of new infections is now around 30, so EVERYONE should be aware and act accordingly.
Latest concerns re TRANSMISSION when with others (friends, family, groups)
When it comes to COVID-19, the evidence overwhelmingly supports aerosol transmission, and there are no strong arguments against it. For example, contact tracing has found that much COVID-19 transmission occurs in close proximity, but that many people who share the same home with an infected person do not get the disease. To understand why, it is useful to use cigarette or vaping smoke (which is also an aerosol) as an analog. Imagine sharing a home with a smoker: if you stood close to the smoker while talking, you would inhale a great deal of smoke. Replace the smoke with virus-containing aerosols, which behave very similarly, and the impact is similar: the closer you are to someone releasing virus-carrying aerosols, the more likely you are to breathe in larger amounts of virus. We know from detailed, rigorous studies that when individuals talk in close proximity, aerosols dominate transmission and droplets are nearly negligible.
If you are standing on the other side of the room, you would inhale significantly less smoke. But in a poorly ventilated room, the smoke will accumulate, and people in the room may end up inhaling a lot of smoke over time. Talking, and especially singing and shouting increase aerosol exhalation by factors of 10 and 50, respectively. Indeed, we are finding that outbreaks often occur when people gather in crowded, insufficiently ventilated indoor spaces, such as singing at karaoke parties, cheering at clubs, having conversations in bars, and exercising in gyms. Superspreading events, where one person infects many, occur almost exclusively in indoor locations and are driving the pandemic. These observations are easily explained by aerosols, and are very difficult or impossible to explain by droplets or fomites.

When we think of COVID-19, we tend to believe it has two distinct types: patients either get very sick and wind up in the intensive care unit or they have a mild form that’s similar to a cold and quickly get better. But it’s now becoming clear that there’s a third category: people who are infected, were not hospitalized (but may have been if hospitals had not been overwhelmed), don’t make a quick recovery, but suffer from long-term and often disabling symptoms.

Covid-19 symptoms vary widely, and undertesting in many countries means that many people may have already had the coronavirus without having received a positive diagnosis. Is it possible to find out, and how should you behave if you think you may have been infected? Link to article
“We don’t think it’s clear yet whether it’s the virus infecting the lungs and the blood vessels, or if it’s the body’s immune system which goes out of control which then causes lung and blood vessel injury,” Darley said. “Or, it could be a combination of both.
