I do not understand that. Does that mean there were two simultaneous outbreaks independent of each other?

it does not said that but it identified 3 type of virus strain Type A is the one transmitted from in the Animal. type B is derive from it .Type B is the prevalent type in Wuhan

CORONAVIRUS has mutated into three distinct strains to continue its deadly spread across the globe, experts have discovered.
Researchers who mapped some of the original spread of Covid-19 in humans say they have found there are three different, but closely related variants.

They reconstructed the early evolutionary paths of the virus as it spread from the epicentre in Wuhan, China, out to Europe and North America.
By analysing the first 160 complete virus genomes to be sequenced from human patients, scientists found the variant closest to that discovered in bats was largely found in patients from the US and Australia - not Wuhan.
Dr Peter Forster, geneticist and lead author from the University of Cambridge, said: "There are too many rapid mutations to neatly trace a Covid-19 family tree.

"We used a mathematical network algorithm to visualise all the plausible trees simultaneously.
"These techniques are mostly known for mapping the movements of prehistoric human populations through DNA.
"We think this is one of the first times they have been used to trace the infection routes of a coronavirus like Covid-19."

The experts believe the virus - called SARS-CoV-2 - is constantly mutating to overcome immune system resistance in different populations.
They used data from samples taken from across the world between December 24, 2019, and March 4, 2020.
Their findings showed there were three distinct, but closely related, variants of Covid-19, which they called A, B and C.

Researchers found that the closest type of coronavirus to the one discovered in bats - type A, the original human virus genome - was present in Wuhan, but was not the city's predominant virus type.
Mutated versions of A were seen in Americans reported to have lived in Wuhan, and a large number of A-type viruses were found in patients from the US and Australia.

Wuhan's major virus type was B and prevalent in patients from across east Asia, however it didn't travel much beyond the region without further mutations.

The researchers say the C variant is the major European type, found in early patients from France, Italy, Sweden and England.

It is absent from the study's Chinese mainland sample but seen in Singapore, Hong Kong and South Korea.

The analysis also suggests one of the earliest introductions of the virus into Italy came via the first documented German infection on January 27, and that another early Italian infection route was related to a "Singapore cluster".

Well, that's because the thought of India being capable of challenging the West is enough to send anyone into paroxysms of laughter so intense that they'd require assisted breathing more acutely than any COVID-19 patient. I'd say the West thinks of you as lapdogs, but they don't bother thinking of you at all.

Besides, the vast majority of the people around the world are stupid cattle who'll eat whatever grass they're fed. Unfortunately, due to historical circumstance, it's the West that gets to decide what kind of grass to put in the cattle's trough. Yet another sad consequence of China's late industrialization.

As for me, I don't get upset that cattle are becoming more anti-Chinese - they're cattle. They don't think, they have thoughts implanted into them by their owners.

What it used to be when China was weak and beneath notice is irrelevant.

China doesn't want "sympathizers," that's what the poor and pitiful want. What China wants - and what it will get whether given freely or not - is respect.

Wow, chill man. We will talk again when things will actually turn ugly. Till then try not to get spanked in the UK.

Well, it would be a bad bad idea to intentionally get people sick, or potentially sick. No matter who volunteers. That's a big no no in any kind of medical research or treatment development in any country. It's ok to ask sick people to volunteer for an experimental treatment, provided that the patients have been fully informed of the risks and they give full consent to the treatment. It is however not ok to intentionally get healthy people sick under any circumstances. NO! That idea itself is against the very concept of what medicine is about.

The longest and the most important part of the vaccine development is the safety part, as I've mentioned before. Also as I've mentioned before, with any vaccines, we are not simply looking at getting a few million people vaccinated at this moment. We are looking to get BILLIONS and BILLIONS of people vaccinated in the next few decades. Any issues with the vaccine will be magnified many folds. No one will develop a temporary vaccine that will be used in the next few months and later find out that this vaccine causes permanent infertility of young kids when they grow up... If we vaccinate 50% of the population on earth, that will mean the end of mankind...

Another concern is the targeted populations. The coronavirus targets older populations with preexisting conditions. Vaccines will target everyone. that means a large population of young kids, who would otherwise be unaffected by the virus, will be affected by the vaccine. Any longer term side effects of the vaccines WILL have bigger impact on the kids because they have many more years to live. Keep in mind that these little kids most likely will live a healthy and full-filling life without the vaccine...

With vaccines, the goal is NOT to trade lives with the virus. You don't want to have the mentality of "OK, I'm going to kill 1000 with the vaccines, but the virus will kill 10,000". That's not how you look at a vaccine. A vaccine won't save all the 10,000 people that would be killed by the virus without a vaccine. Even with the vaccine, many will still die. Just look at the seasonal flu, even with the mass vaccination that we have now in the US, ~70,000 still died of the flu in the current flu season. Close to 100 million in the US still got infected of the seasonal flu. An effective and safe vaccine will save many, but not all of them. So with a questionable vaccine, you will have people dying of the virus (unable to be saved by the vaccine) AND people killed by the vaccine itself. What you end up with is not much of a difference. What is different is that many people, who would otherwise show little symptom to the virus, will be killed by the vaccine.

Wishing for a vaccine as this point is highly unrealistic. No responsible pharmaceuticals nor medical researchers will release a premature vaccine at this point. No one!

speaking of vaccines,

"As of 8 April 2020, the global COVID-19 vaccine R&D landscape includes 115 vaccine candidates (Fig. 1), of which 78 are confirmed as active and 37 are unconfirmed (development status cannot be determined from publicly available or proprietary information sources)."

I am in the air-conditioning business, let me answer some of your questions,
. HEPA filters on air handling units are only found on special applications i.e hospital operating theatres, production purpose i.e electronics, the reason you won’t find them on comfort cooling application is everything from equipment designed to use and power consumption is very expensive.
. The universal optimum temperature of air-condition space is 24 deg.C but of course the lower the temp.Is set the higher the power consumption as you have pointed out.
. Central air -conditioning duct work is a main source of spreading all kinds of nasty due to either because the building is old or because the duct work is filthy due to failure of proper maintenance done, that is air filter changed regularly or washed. Note:- HEPA filter is not only expensive but are of throw away use, cannot be serviced.
.Been in the industry for 36 years, had never come across UV light to kill bacteria on central air-conditioning applications.
Hope this clears up some of your concerns, cheers and stay safe.

Kienchin, I read somewhere that HEPA filter can only filter out bacteria but not virus which is smaller than bacteria. Am I correct ?

Chinese doctors garrisoning in Africa hold the fort during pandemic

Since 1963, China has sent around 21,000 medical personnel to African countries, helping 220 million patients there, which has been praised throughout the continent. The Chinese medical team is the most distinguished and longest cooperation project between China and Africa, involving most countries and regions, according to the China-Africa Institute.

When the COVID-19 pandemic spread around the world, current Chinese medical teams garrisoning in several African countries, such as Sudan, Ethiopia and Cameron, work to help local prevent the deadly disease.

Equatorial Guinea has close cooperation with China and is willing to learn China's experience, Chen Shuo, a deputy director of ophthalmology in Dongguan Songshanhu Central Hospital and member of the 30th batch of medical team aiding the Republic of Equatorial Guinea from South China's Guangdong Province, told the Global Times.

According to China Central Television, Equatorial Guinea reported its first confirmed case of COVID-19 on March 15, the day it announced the closure of schools, strict quarantine and testing procedures, and enhanced immigration control.

"When the novel coronavirus was found in other countries, the country began to remind people to wash their hands and wear face masks through mobile phone messages. Local epidemic prevention and control was conducted timely," Chen said.

Chen acted as the leader of medical team at Malabo, the capital of Equatorial Guinea.

The Chinese medical team selected the latest prevention and treatment plan of COVID-19 and some effective prevention and treatment experience in China, translated it into Spanish, and sent it to the Ministry of Health of Equatorial Guinea.

Medical experts in Beijing with substantial experience against COVID-19 gave online lectures about the latest and detailed exploration to Chinese medical staff aiding Africa to better assist locals fighting against the pandemic.

"For example, chloroquine was found to be effective in the treatment of novel coronavirus in China. These are the experiences of frontline doctors in China accumulated through thousands of cases, which we hope to convey to Africa. We also teach and explain the use of ventilator. Local medical resources are scarce, and there are few local doctors who can skillfully operate the ventilator," Chen introduced.

Lol. Tell that to the Africans and the African Union that ironically defended tedros after trump slammed him.

Anyway enjoy the comments from Ghana, an 'ally' of China.
