Will there be a second wave of coronavirus?

With more countries planning to reduce restrictions imposed due to the coronavirus -- United Kingdom Prime Minister Boris Johnson and German Chancellor Angela Merkel -- worry about the potential of a “reanimation” or second wave.

But will there be a second wave?

As it says The Guardian, conveys Telegraph, epidemics of infectious diseases behave in various ways but the 1918 flu pandemic that killed more than 50 million people and is regarded as a typical example of a pandemic that occurred in many waves, with the second heavier than the first.

This has been repeated despite the mildest in the subsequent pandemics.

Other flu bodies included in 1957 and 1968 all had multiple waves.

The H1N1 2009 flu pandemic began in April and was followed, in the US and the northern hemisphere, by a second wave in autumn.

How and why numerous wave explosions occur, and how later waves of infection can be prevented, has become an element of epidemiological modeling studies and preparation for pandemics, which have looked at everything, from social behavior and health policies, to inoculation and <x0 community immunity construction”, also known as “

While the second wave and secondary peaks within the period of a pandemic are technically different, concern is essentially the same: the disease can be powerfully converted.

Is there evidence that the coronavirus is back somewhere?

This is being seen very carefully.

Without a vaccine, and without widespread immunity to the new disease, an alarm is being sounded from Singapore's experience, the country that has seen an unexpected “reanimate <x1nd of infections, despite being praised for the early treatment of the explosion.

Although Singapore created a strong system for tracking contact for the general population, the disease resurfaced in the sharp accommodation of dormitories used by thousands of foreign workers with inadequate sanitation and common management.

With 1,426 new cases reported Monday and nine dormitories, the largest of which holds 24,000 men declared isolation units, Singapore's experience, although very specific, has demonstrated the disease's ability to return powerfully to countries where people are in the vicinity and the ability of the virus to exploit every weakness in public health regimes designed to fight it.

And despite China's obvious success in bringing the explosion to Hubei province, there has been an increase in cases north of the country.

A new group of coronavirus cases in the northern-East city of Harbin near the Russian border has forced authorities to impose new deadlocks after reporting local broadcasts in recent weeks.

All of this raises questions about when, and how to reduce deadlocks to avoid a second wave or “reanimate”.

What do experts worry about?

Conventional wisdom among scientists suggests that the second wave of resistant infections occur after the capacity for treatment and isolation becomes exhausted.

In this case the concern is that the social and political consensus supporting the impasse is being “defeated” by the public disappointment that has triggered protests in the US and elsewhere ) and the urgent need to reopen economies.

The threat falls when the population's sensitivity to the disease falls under a certain threshold or when widespread vaccine becomes available.

In general terms, the ratio of sensitive and immune individuals to a population at the end of a wave determines the possible size of a later wave, sends in the Telegraph.

The concern now is that with a vaccine still a few months away, and with a real rate of infection still assuming, populations around the world remain quite sensitive to both “rest” and the following waves.

Justin Lesser, an associate professor of epidemiology at Johns Hopkins University, wrote surprisingly about the Washington Post in March: “The epidemics are like fires. When fuel is abundant, they become enraged uncontrollably, and when it is scarce, they slowly burn”.

Epidemiologists call this intensity “infection”, and the fuel that drives it is population sensitivity to pathogens.

While repeated outbreak waves reduce sensitivity (both through full or partial immunity), they also reduce the power of infection, reducing the risk of the disease even among those with no immunity.

The problem is that we don't know how much “carburant” is still available to the virus.
