Nu ai cum sa opresti infectarea asa usor... is zeci de mii de oameni care au fost in zona aia si au plecat. e o zona mare , f populata , lumea se misca.

Acum conteaza doar cat de puternica e infectarea si cat de usor se transmite virusul. Daca e pe cale de aer... atunci e o problema mare de tot.

Serpii vanduti in piata fara norme sanitare ar fi rezervorul de virus iar comerciantii de acolo pacientii zero, de aia s-a raspandit usor la clienti si dupa aia unii de la altii.

is altii care spun ca de la liliac... ma uitam pe flipboard...

virusul apare de la mizerie? sau e o mutatie in animalul respectiv din cauze naturale?

poti sa creezi un virus? sau poti doar sa schimbi un virus in altul?

Nu e asa usor ca trebuie sa fie functional adica datele alea chiar sa faca ceva... secventele sufera mutatii, unele utile ajung sa se promoveze.
Virusurile nu sunt vii... ei nu pot trai fara gazda, sunt colectii de ARN/RNA. Cum ajung sa muteze e ceva ce numai microbiologii pot explica, trebuie cautat documentatie de specialitate.

Cateva statistici interesante, cunoscute pana la aceasta ora.

[attachment=2338608:coronavirus1.jpg] [attachment=2338609:coronavirus2.jpg]

[attachment=2338610:coronavirus3.jpg]

Quick Facts :
  • The 2019 novel coronavirus (2019-nCoV, or Wuhan coronavirus) has spread to 19 countries and territories worldwide, with 6,097 confirmed cases and 132 deaths as of January 29, 2020.

  • In the United States, there are 5 confirmed cases by the CDC: 1 in Arizona, 2 in California, 1 in Washington state, and 1 in Illinois.

  • Wuhan (the city where the virus originated) is the largest city in Central China, with a population of over 11 million people.

  • Germany, Japan and Taiwan have reported the first cases in patients who didn't’t personally visit China, but contracted the virus from someone else who had visited Wuhan, China.

  • A pathogen’s harmfulness is determined by the combination of Ro (reproductive number) and the case fatality rate.


Reproductive Number (Ro) of 2019-nCoV

The novel coronavirus' reproductive number (Ro, pronounced R-nought or r-zero), which measures how rapidly a disease spreads, is estimated at the highest value ever recorded: 3.8, according to preliminary studies [5][6]. For comparison, the RO for the common flu is 1.3 and for SARS it was 2.0. Ro represents the average number of people who will catch the disease from a single infected person, so if R0 for coronavirus is 3.8, it means that on average every case of novel coronavirus would create nearly 4 new cases.


Fatality Rate of 2019-nCoV

The novel coronavirus' case fatality rate is currently estimated at around 2%. For comparison, the case fatality rate with seasonal flu is less than 0.01% (1 death per every 10,000 cases)[7]. Fatality rate for SARS was 10%, and for MERS 34%.


Comparisons:
  • Every year an estimated 290,000 to 650,000 people die in the world due to complications from seasonal influenza (flu) viruses. This figure corresponds to 795 to 1,781 deaths per day due to the seasonal flu.

  • SARS (Nov. 2002 - Jul. 2003): was a coronavirus that originated from Beijing, China, spread to 29 countries, with 8,096 people infected and 774 deaths (with a fatality rate of 9.6%).

  • MERS (2012) killed 858 people out of the 2,494 infected (with a fatality rate of 34.4%).

iti explic eu. ai auzit de tehnica CRISPIR? cam asa ceva se intampla cu virusii. o particula din aer patrunde prin invelis si muteaza o secventa ADN. asta se poate intampla inclusiv la oameni.
ce inseamna muteaza? pur si simplu indeparteaza o secventa ADN sau o muta altundeva pe spirala si astfel apare un nou specimen. sunt miliarde de mutatii care se intampla in aerul deschis insa numai cateva reprezinta de fapt adaptari la mediu , pur si simplu evolutia triaza miliardele alea de mutatii
