Latin America and South Asia did not reach at peak yet. Africa is just rising. If it's happened then good for all but the situation does not in favor of just a month dear Dr. Nasser Said Gomaa Abdelrasheed
The mistake of opening lockdown too early has killed lots of people already. It is like a new wave, but this one is intentional.
Around here (Canada) the lockdown is lifted, but everyone is still keeping the distance, too scared to meet people, go to stores and still avoiding restaurants (although they open up slowly). The new waves are happening in big cities and factories that are "forced" to open.
The second wave that is gradually unfolding is due to human contacts which is potent enough to create an endemic situation. The cases in Nigeria has been surging in recent days after restrictions are gradually been relaxed by the government. Its likely the world will not be free as soon as we are thinking if appropriate measures are not taken as the second wave may be deadlier than the first
The answer to this question will depend on the measures put in place by governments after the lifting of containment, but one thing is certain: the second wave of contamination may be more or less severe than the first. Scientists agree that too sudden a relaxation of control measures could result in a rapid rise in the number of cases and a return of severe forms to hospital and intensive care. A recent study showed that measures taken against virus transmission contribute to a reduction in the development of herd immunity; "leading to the possibility of a second wave of infections" once these measures are lifted.
With the lifting of containment, fears on both sides are enormous over the return of a second wave of the Covid-19 epidemic. But some scientists, however in minority positions, believe that this second wave will not come.
It’s iconoclastic, but no more so than the WHO (World Health Organization) which says that the coronavirus can never disappear, says epidemiologist Laurent Toubiana. My thesis is that there is no second wave, he continues.
No second wave, this means no massive influx of patients caused by the release from confinement, which could overwhelm resuscitation services. The media bridgehead of this theory is Professor Didier Raoult. Nowhere is there a second wave […] Eventually some sporadic cases will appear here or there (but) the epidemic is ending, specifies this last.
In my opinion too, even if the uncertainty remains, several indicators suggest a contained risk, at least in the short term. In other words, the worst is behind us. However, this situation should be taken with great caution, because even if we do not see a second wave in any country in the world, only sporadic cases and re-imports from the current pandemic phase, nothing is definitively sure with a pandemic.
Warning: patients having recovered from COVID-19 may be getting reinfection due to the false-sense of security of being immune to COVID-19.
Not only the relaxations in lock downs causing a resurgence of increased number of COVID-19 cases in certain areas, a real problem is that patients who have recovered from COVID-19 and not taking social distancing, and other preventive measures due to false belief that they are immune, are being reinfected.
Until proven otherwise, even after having recovered from COVID-19, they should not forgo the preventive measures for COVID-19.
We are now seeing patient with COVID-19 after testing negative and still being cohorted with other COVID-19 patients are becoming again reinfected.
It depends on whether the new varieties of SARS-CoV-2 Coronavirus (causing Covid-19 disease) that arise as a result of constant mutations will also cause specific disease symptoms. The key issue is whether the natural immunity obtained by humans after infection with SARS-CoV-2 Coronavirus and more or less mild illnesses on Covid-19, recovery will still be active against new varieties of Coronavirus or whether new varieties of Coronavirus that will be created in the coming years will be significantly different analogously as in the case of influenza virus.
In Italy the number of infections has never reached zero. If common sense rules (e.g. social distance, use of PPE) are not adopted, a second wave can be expected.
Surprisingly, the WHO denies the concept of waves (i.e. significant epidemiological changes in the number of infections). I personally believe that, in the current global situation, the limitation of restrictive measures inevitably leads to an increase in the human-human transmissibility of SARS-CoV-2.
When an infectious disease starts, it increases at an exponential rate, reaches its peak and then declines substantially due to preventive measures undertaken such as lock downs. For the ending of the first wave of COVID 19 pandemic, the virus should have been fully controlled, which is rather impossible, as there remains many asymptomatic and symptomatic individuals, and also vast majority of the peoples are still susceptible to the virus. So, another wave will start with a sustainable rise in infection, leading to second wave of infection, after the with drawl of lock down.
Thanks for nice sharing dear Munira Nasiruddin and there is still confusion about second wave or second peak of the first wave in different countries. Covid-19 is spreading in "one big wave" and is not affected by seasonal trends, according to World Health Organization (WHO) spokesperson Margaret Harris. Hong Kong thinks about third wave. China, Australia, Spain, Japan all facing second wave of cases. USA, Brazil and India are still in the first wave with several peaks. Whatever it is we need to preventive measures to protect ourselves.
and it's an arbitrary cut off point for second or third wave actually. WHO thinks first wave for many countries but doesn't deny for the second wave. Yes, USA, Brazil, India are still in the first wave but Hong Kong thinks third wave of new cases for their country. The UK is thinking for second wave and new outbreaks are in other countries like Australia, Spain, Germany Japan, China, Belgium etc. Nothing is absolute here and it varies according to country context.
Slum dwellers, rickshaw pullers, day laborers and destitute are not under lock down in Bangladesh. But they are not under threat of Covid-19, so far we have observed. So, with drawl of lock down and another wave are for whom? We have to rethink the matter deeply that present action of Covid-19 is for whom and why?
Thanks dear M. A. Azadi . Bangladesh is not an example only...look at USA, Europe, latin America please. India reports >50,000 cases 7 days in a row..take a lesson from China where they can conduct more than a million tests per day..hope you can guess better now...Follow WHO's bulletin and you can hear Fauci too...science is more important than politics and emotions...Fauci said it.
Thanks dear Muhammed Ashraful Alam for your nice global analysis. Yes, it is 100% true that science is more important than politics and emotions----as Dr Fauci said. Yes, I know the rate of variation of infection in different countries. Except Educational Institutions and high quality rich peoples, no where in Bangladesh absolute lock down is maintained. Rather, some areas (as I mentioned) are exposed to open air directly and mostly unhygienic conditions prevail there, and also no lock down is maintained there. But the rate of infection is found to be very low compared to the peoples maintaining more hygienic condition. So, I pointed out, natural adaptation is more important than hygienic condition, which should be considered deeply.
Think so dear Dunya Mohamed Hameed and new outbreaks are in so many countries (Europe, Australia, Japan, Hong Kong, China, Vietnam, New Zealand etc.) and the pandemic is still roaring.
and no need to be a scientist or physician to comment on it. You are absolutely fine to describe and global cases are now more than 21.3 million and USA alone has more than 5.4 million cases. Latin America tops 6 million cases and India hits 2.5 million. Europe is worried again with new outbreaks. Same in Japan, Hong Kong, Australia, New Zealand, China, Vietnam etc. -all are in crisis actually. Cases are rising in Africa too and the pandemic is still roaring across the world. It's beyond control and the world is in the vaccine race. And confusion and controversy are also there.
Yes, I think, after the withdrawl of lock down, another wave of COVID-19 will come, and it is already being experienced in some countries. People will have an open acess to movement and contamination and this will be the cause of increase of infection and hence the possibility of another wave.
Yes, but it is difficult to predict the scale of the development of the second wave of the SARS-CoV-2 (Covid-19) coronavirus pandemic. This process has already started in some countries around mid-August 2020. Then the scale of new SARS-CoV-2 coronavirus infections began to increase. However, earlier, in May - June, many countries began to lift anti-pandemic restrictions to a greater or lesser extent (e.g. wearing protective masks, restrictions on the movement of citizens in public places, home quarantine, closed service establishments and institutions, etc.) or their reduction. scale. In addition, in the period June - July 2020, the holiday and tourist season began in many countries. Lifting anti-pandemic restrictions and withdrawing lockdown were indirectly related to the issue of the beginning of the tourist season and to the previously demonstrated decreasing level of new infections and the increasing number of people who recovered from Covid-19 disease (May - August 2020). However, this is history and now more and more data appearing in the media suggest that now (at the end of August 2020) the second wave of the SARS-CoV-2 (Covid-19) coronavirus pandemic is already starting.
Sometimes it's difficult to draw a demarcation line between first wave and second wave of cases dear Sonika Kumari . We have seen so many peaks in the first wave of USA, India and Latin America whereas Europe, Australia, New Zealand, Japan, South Korea are worried about second wave and Hong Kong just faced its third wave of cases.
