Coronavirus Covid-19 - opšta tema

[steins]

 
Privatna? Idioti.

Da da. Samo je jedno, mislim Delta, al mi nemoj verovati, rekla da mora da joj se javi ukoliko neki od osigiranika dodje sa suspektnim COVIDom, ali nisu dali dalje instrukcije.

ima li neko od naših italijana ili @vememah, nekuzvaničnu italijansku statistiku od broju umrlih od covida u odnosu na sezonski grip ?

 

čini mi se da se pojavljivao neki grafikon ali sada ne mogu da ga nađem, a moram nekima da predočim da me se više okanu

To je sigurno veemah bio, saće on sa graficima... ipak ne sećam se da sam video.
Zadnjih par godina po oko 8 miliona gripoznih bilo, ako ne i duplo...

samo što za smrtnost nema nekih brojeva jer se retko radio neki test prilikom autopsije da se zna dal je grip u uzrokovao/doprineo ali procena je 8.000 do 12.000 godišnje

Imas npr i broj umrlih od gripa u hrvatskoj za celu sezonu bude 20-100, kako kad. Danas su bas objavili da su zakljucili sezonu gripa al sam zaboravila koliko su pobrojali, 20ak

Sad uzmes da je trajao mnogo duze nego covid za sad i da je tamo uz sve mere do danas 55 smrtnih slucajeva jasna je usporedba

 

Ovo prilazem jer je italija drastican primer (odredjene opstine ovde date) a cro je npr prosecno pogodjena covidon

Verujem da se mogu brojke za grip izGuglati i za srbiju, ako ne za ovu onda za prosle sezone

 

Primetno je da u tim godisnjim izvestajima hrvati daju i broj vakcinisanih te sezone i isticu vezu sa brojem umrlih

vec sam pomijala - tokom epidemije h1n1 - od juna 2009. do marta 2010. preminulo je 137 osoba (registrovani samo oni koji su umrli u bolnici).

Evo za ovu sezonu evropa influenza, ima dole grafik

Ja se uopste ne secam neke frke kod nas oko toga, a bas je bilo lose, prema tom podatku

 

Evo za USA h1n1 vs covid19

 

From April 12, 2009 to April 10, 2010, CDC estimated there were 60.8 million cases (range: 43.3-89.3 million), 274,304 hospitalizations (range: 195,086-402,719), and 12,469 deaths (range: 8868-18,306) in the United States due to the (H1N1)pdm09 virus.

 

USA covid19 do sada ima vec preko 55000 preminulih

Interview

Germany's Covid-19 expert: 'For many, I'm the evil guy crippling the economy'

Laura Spinney

Germany’s leading coronavirus expert Christian Drosten on Merkel’s leadership, the UK response and the ‘prevention paradox’

Sun 26 Apr 2020 12.00 BST
Last modified on Sun 26 Apr 2020 18.40 BST

Christian Drosten, who directs the Institute of Virology at the Charité Hospital in Berlin, was one of those who identified the Sars virus in 2003. As the head of the German public health institute’s reference lab on coronaviruses, he has become the government’s go-to expert on the related virus causing the current pandemic.

In an exclusive interview, Drosten admits he fears a second deadly wave of the virus. He explains why Angela Merkel has an advantage over other world leaders – and why the “prevention paradox” keeps him awake at night.

Q: Germany will start to lift its lockdown gradually from Monday. What happens next?
A: At the moment, we are seeing half-empty ICUs in Germany. This is because we started diagnostics early and on a broad scale, and we stopped the epidemic – that is, we brought the reproduction number [a key measure of the spread of the virus] below 1. Now, what I call the “prevention paradox” has set in. People are claiming we over-reacted, there is political and economic pressure to return to normal. The federal plan is to lift lockdown slightly, but because the German states, or Länder, set their own rules, I fear we’re going to see a lot of creativity in the interpretation of that plan. I worry that the reproduction number will start to climb again, and we will have a second wave.

Q: If the lockdown were kept in place longer, could the disease be eradicated?
A: There is a group of modellers in Germany who suggest that by prolonging lockdown here for another few weeks, we could really suppress virus circulation to a considerable degree – bringing the reproduction number below 0.2. I tend to support them but I haven’t completely made up my mind. The reproduction number is just an average, an indication. It doesn’t tell you about pockets of high prevalence such as senior citizens’ homes, where it will take longer to eradicate the disease, and from where we could see a rapid resurgence even if lockdown were extended.

Q: If there were such a resurgence, could it be contained?
A: Yes, but it can’t happen based on human contact-tracing alone. We now have evidence that almost half of infection events happen before the person passing on the infection develops symptoms – and people are infectious starting two days prior to that. That means that human contact-tracers working with patients to identify those they’ve been exposed to are in a race against time. They need help to catch all those potentially exposed as quickly as possible – and that will require electronic contact-tracing.

Q: How close we are to achieving herd immunity?
A: To achieve herd immunity we need 60-70% of the population to carry antibodies to the virus. The results of antibody tests suggest that in Europe and the US, in general, we are in the low single digits, but the tests are not reliable – all of them have problems with false positives – and herd immunity is also not the whole story. It assumes complete mixing of the population, but there are reasons – in part to do with the social networks people form – why the whole population may not be available for infection at any given time. Networks shift, and new people are exposed to the virus. Such effects can drive waves of infection. Another factor that could impact herd immunity is whether other coronaviruses – those that cause the common cold, for example – offer protection to this one. We don’t know, but it’s possible.

Q: Should all countries be testing everybody?
A: I’m not sure. Even in Germany, with our huge testing capacity, and most of it directed to people reporting symptoms, we have not had a positivity rate above 8%. So I think targeted testing might be best, for people who are really vulnerable – staff in hospitals and care homes, for example. This is not fully in place even in Germany, though we’re moving towards it. The other target should be patients in the first week of symptoms, especially elderly patients who tend to come to hospital too late at the moment – when their lips are already blue and they need intubation. And we need some kind of sentinel surveillance system, to sample the population regularly and follow the development of the reproduction number.

Q: What is known about the seasonality of the virus?
A: Not a lot. The Harvard modelling group led by Marc Lipsitch has suggested that transmission might slow over the summer, but that it will be a small effect. I don’t have better data.

Q: Can we say for sure that the pandemic started in China?
I think so. On the other hand, I don’t assume that it started at the food market in Wuhan. It is more likely to have started where the animal – the intermediate host – was bred.

Q: What do we know about that intermediate host – is it the “poor pangolin”, as it’s come to be known?
A: I don’t see any reason to assume that the virus passed through pangolins on its way to humans. There is an interesting piece of information from the old Sars literature. That virus was found in civet cats, but also in raccoon dogs – something the media overlooked. Raccoon dogs are a massive industry in China, where they are bred on farms and caught in the wild for their fur. If somebody gave me a few hundred thousand bucks and free access to China to find the source of the virus, I would look in places where raccoon dogs are bred.

Q: Will it be useful to identify patient zero – the first human to have been infected with this virus?
A: No. Patient zero is almost certain to have acquired a virus that is very similar to some of the first sequenced viruses, so it wouldn’t help us solve our current problem. I don’t think you could even argue that it would help us prevent future coronavirus pandemics, because humanity will be immune to the next Sars-related coronavirus, having been exposed to this one. Other coronaviruses could pose a threat – a prime candidate is the Middle East respiratory syndrome (Mers) virus – but to understand that threat we have to study how Mers viruses are evolving in camels in the Middle East.

Q: Are human activities responsible for the spillover of coronaviruses from animals into people?
Coronaviruses are prone to switch hosts when there is opportunity, and we create such opportunities through our non-natural use of animals – livestock. Livestock animals are exposed to wildlife, they are kept in large groups that can amplify the virus, and humans have intense contact with them – for example through the consumption of meat – so they certainly represent a possible trajectory of emergence for coronaviruses. Camels count as livestock in the Middle East, and they are the host of the Mers virus as well as human coronavirus 229E – which is one cause of the common cold – while cattle were the original hosts for coronavirus OC43, which is another.

Q: Flu has always been thought to pose the greatest pandemic risk. Is that still the case?
A: Certainly, but we can’t rule out another coronavirus pandemic. After the first Ebola outbreak, in 1976, people thought it would never come back again, but it took less than 20 years to do so.

Q: Is all the science being done around this coronavirus good science?
A: No! Early on, in February, there were many interesting preprints [scientific papers that have not yet been peer-reviewed] around. Now you can read through 50 before you find something that’s actually solid and interesting. A lot of research resources are being wasted.

Q: Angela Merkel has been praised for her leadership during this crisis. What makes her a good leader?
She’s extremely well-informed. It helps that she’s a scientist and can handle numbers. But I think it mainly comes down to her character – her thoughtfulness and ability to reassure. Maybe one of the distinguishing features of a good leader is that they are not using this present situation as a political opportunity. They know how counterproductive that would be.

Q: From where you stand, how is the UK handling the situation?
A: It’s clear that testing was implemented a little bit too late in the UK. Public Health England was in a position to diagnose the disease very early on – we worked with them to make the diagnostic test – but rollout in Germany was driven in part by market forces, which made it fast, and that wasn’t the case in the UK. Now, though, I have the impression that the UK is really gaining momentum in this regard, and that it is coordinating testing efforts better than Germany.

Q: What keeps you awake at night?
A: In Germany, people see that the hospitals are not overwhelmed, and they don’t understand why their shops have to shut. They only look at what’s happening here, not at the situation in, say, New York or Spain. This is the prevention paradox, and for many Germans I’m the evil guy who is crippling the economy. I get death threats, which I pass on to the police. More worrying to me are the other emails, the ones from people who say they have three kids and they’re worried about the future. It’s not my fault, but those ones keep me awake at night.
