Reproduction coefficient may refer to various quanitties:

Reproduction of photons in a cavity with active medium,

Reproduction of electrons in photomultiplier or in a Geiger counter

multiplication of number of neutrons in nuclear reactor,

multiplication of number of patients due to transmittance of some decease,

etc.

In particular, term Reproduction coefficient is applied to spreading of infection Covid19. The same quantity is denoted also with term Rnumber (or R number). This number is average number of new patients, who get ill due to contact with one ill person.

Covid19

Sparse data on R

China

For Wuhan, 2020.01.24, R is estimated to range from 3.6 to 4 [1]

For China, since 2020.01.01 to 2020.02.07, R is estimated to range from 1.4 to 6.49, with mean 2.28 [2]

UK

2020.09.18, in the UK R coefficient is estimated to be between 1.1 and 1.4 [3]

Masks

     Efficiency of masks [4]

Use of face masks is reported to reduce the coefficient R for one or two orders of magnitude.

Efficiency of medical mask is estiamted as

\(E = 1-R/R_0 \)
where
\(R_0\) is reproduction coefficient under condition, that the people do not use the face masks, and
\(R\) is the reproduction coefficient under condition, that all the people use masks in public places.

Various estimates for the efficiency are suggested in year 2020:

2020.04.19, intyroverts estimate of the efficiency to be 98.5% [5]

2020.04.23, myupchar.com estimate of the efficiency to be 97% [6].

2020.05.04, nashaniva estimates the efficiency of masks almost 100% ("В масках вероятность заражения снижается до минимума") [7].

2020.05.04, Саулюс Чаплинскас estimates the efficiency of masks to be 98.5% [8].

2020.06.02, Rachael Rettner suggests the estimate of the efficiency 85% [9][10].

2020.06.04, Ирина Иванова estimates the efficiency of masks more than 90% (probability of transfer reduces tens times, "при ношении масок риск заразиться коронавирусом снижается в десятки раз") [11][12].

2020.07.21, don24 repeats the same estimate, more than 90%. [13].

Second wave of covid19

\(\phantom{012345678901234567}\)

According to the estimates of the efficiency of masks, since the mass use of the face masks, the reproduction coefficient of Covid19 should be significantly below unity.
Since the 2020 spring, almost 100% of people wear masks in the public places.
So, the pandemic is supposed to decay exponentially.
Then, the "second wave" [15][16][14] of Covid19 cannot be attributed to the unwanted transfer of the infection from ill pacients to new victims.

The reasonable hypothesis explains the "second wave" as manifestation of the total hybrid Putin world war of the Russian officials against the Human civilization.

Under condition of total corruption of the top Russian officials, there are no mechanisms that would prevent them from using of bioweapon in this war; the aliases of the Russian usurper, like Boshirov and Petrov, intentionally spread the infection, in the same way, as they apply unstable nuclei of Po-210 or poison novichok for murdering.

This concept shows good agreement with reports about use of the Russian diplomatic post for contraband. Centners of cocaine, Po-210, Novichok, highly pure biopreparate and other weapon of mass murdering can be smuggled with the Russian diplomatic post.

The Pasechick institute and GNC Vektor are reported to manufacture bioweapon. These facilities are located in Russia. So, the intentional spreading of infection by the Russian terrorists appears as natural and reasonable hypothesis. This hypothesis shows good agreement with other evidences of terroristic activity of the Russian proxies. After to shout down the passingers airplanes (see Katyn-2, MH17), to use the nuclear weapon (see Putin kiled Litvinenko, to use the chemical weapon (See 2018.03.04.Теракт, in Russian), one could expect, that the Russian terrorists will use the bioweapon too. It could be delivered with the diplomatic post; use of the Russian diplomatic post for contraband is also reported (see Кокаин в диппочте, in Russian).

Carriers of the Russian diplomatic passports appear as the main suspect in the terroristic attack on all the countries. The attack with bioweapon perfectly fits the general concept of the hybrid war. Within this concept, the civilized countries should consider ways to resist: search well the Russian diplomatic post and detend, interrogate the Russian officials, especially carriers of the diplomatic passports, as the primary suspects.

Comments// By Mathieu Pollet • last updated: 05/10/2020 - 14:06 Countries across Europe are seeing a resurgence in COVID-19 cases after successfully slowing outbreaks early in the year.// Some countries — such as Albania, Bulgaria, Czech Republic, Montenegro, North Macedonia — are seeing higher case numbers than earlier in the year.// France, the UK, Poland, the Netherlands and Spain are likely dealing with the much-feared second wave and have started taking action to curb it.// While on the face of it infection numbers might be higher, it could be accounted for by the increase in testing - many countries didn't have the capacity to carry out tests in such a high volume earlier in the year.

TOKYO -- A hospital in the capital has once again set aside beds normally used by regular inpatients for those infected with the COVID-19 virus in response to instructions by the Tokyo Metropolitan Government following a resurgence of infections.// Amid the "first wave" of infections, the Japanese Red Cross Musashino Hospital in the suburban Tokyo city of Musashino had converted a total of 30 beds, including 20 beds for regular patients and 10 high care unit beds, into those for use by patients infected with the novel coronavirus. After the state of infections settled down, in May the hospital left five intensive care unit beds for COVID-19 patients and restored the rest to regular use. However, following a request by the metropolitan government, which aims to secure a total of 2,800 beds, the hospital has once again converted 20 regular patient beds into those designated for COVID-19 patients.

Japan is now “in the midst of a second wave” of COVID-19, warned an infectious disease expert on Aug. 19, in stark contrast to the central government. // The government has long stopped short of labeling the surge in new cases since early July as such.// “We were able to somehow overcome ‘the first wave’ after the state of emergency was declared," said Kazuhiro Tateda, the head of the Japanese Association for Infectious Diseases, speaking at the annual conference that began in Tokyo on Aug. 19. "But we are now in the midst of a second wave.”
