Stepping up the combat against COVID-19. India’s Ministry of Health & Family Welfare recently declared sector-wise category of districts as hotspots (red area) and non-hotspots (green region), based on reported cases.

Districts without instance are categorize as green. A hotspot district can circulate to the green region if no new case mentions for 28 days.

States are advised to perceive hotspots primarily based on the doubling rate of confirmed cases. This identity of hotspots, the Ministry says, will complete on a weekly foundation if no longer earlier. Strict containment measures are to carry out in those hotspot areas.


Over to the east of India lies Bangladesh. It, too, became pretty unscathed in the 2020 waves of the pandemic. However, this has caused humans to become complacent about the virus and now not adhere to social distancing measures. March and April saw a next upward push in COVID instances in Bangladesh, which precipitated the government to impose new regulations. On April 19, Bangladesh recorded its highest each day dying rate at 112 deaths. A complete lockdown changes into carried out on April 14.

Since instances started to push upward, the authorities have imposed restrictions following the lockdown. A ban on public gatherings in regions where infection charges are excessive and a journey ban to and from countries the authorities consider an overblown threat. Planned elections for a few areas got postponed. Vaccinations are underway, however, progressing slowly, with only 2. Eighty-one million have received both doses of the vaccine, and approximately eight million doses are given. The key for Bangladesh is to hope that India’s issues no longer spill over the border and wreak havoc on the healthcare gadget. The government and fitness officers must now work challenging to convince the population. People must take this virus critically, and restrictions must be adhered to.


Two nationwide COVID-19 antibody seroprevalence research from Brazil displays that many cities along the Amazon had been hit the toughest at the start of the epidemic in May and June, at the side of poorer and Indigenous groups.

“Existing seroprevalence research in Brazil has focused on the extra evolved parts of the USA. It is representing the aid of the southern and southeastern areas. So it’s crucial that we have extra accurate information about the national situation.”

The researchers conducted two household surveys in the most populated cities in 133, known as ‘mesoregions’. The Brazilian Institute of Geography and Statistics used a regional hub to record demographic and socioeconomic information across Brazil. Hence, overlaying 26 states and the Federal District.

The studies included greater than 25000 participants inside the length of May 14-21 and over 32000 from June four-7. At each place, the researchers randomly selected families and decided on one man or woman from all household contributors to check for COVID-19 antibodies.

Participants additionally responded to short questionnaires on sociodemographic statistics (intercourse, age, training, ethnicity, household size, and household property) and compliance with bodily distancing measures.

 Most amazing locating changed into the cluster of high prevalence in eleven cities alongside the Amazon River. Along with ranges that were the various highest ever said in population-based studies. This finding of high occurrence in a tropical area contradicts commonplace understanding. The continents such as Africa are probably included in opposition to COVID-19 because of high ambient temperature.”

Some Beliefs of Authors

The authors believe the high seroprevalence rates in Indigenous Brazilians are due to a geographical area. Along with family length (generally overcrowded residing conditions), and poverty. Mortality charges for most clinical conditions are better in Indigenous Brazilians. After all, this population turned primarily left at the back throughout Brazil’s speedy financial and fitness advances that commenced in the Nineteen Nineties.

The authors say: “All should interpret our consequences in phrases of the debatable control of the pandemic by using the national government. Testing becomes constrained to individuals with intense signs throughout the early degrees of the pandemic. Let’s get in touch with tracing turned into simply non-existent. Two consecutive fitness ministers have to resign in less than one month. Due to their opposition to the president’s stance concerning physical distancing and the usage of hydroxychloroquine to treat COVID-19. After seeing that May 15, the United States has not had a health minister… The controversial coping with the epidemic by suing the federal government probably contributed to the speedy unfold of COVID-19 in the united states’ most susceptible populations.”

While to start with, many kingdom governors have supported social distancing measures and a few forms of lockdown. Some have now progressively reopened, despite the persisting excessive incidence of the latest instances and deaths.

The authors conclude: “The effect of relaxing those measures continues to be too early to assess. However, in addition, waves of serological surveys will allow monitoring of the progression of the pandemic and help check the effectiveness of coverage modifications.”

The authors have additionally executed extra seroprevalence surveys* since the mentioned in this paper. Therefore, with an average prevalence of 3.Eight% within the 1/3 look at from June 21-24. Observing through a pointy decline to at least one. 4% within the ultimate survey round, achieved from August 27-30, after a c programming language of 66 days.


This amazed the researchers because they look ahead to cumulative seroprevalence to keep rising (seroprevalence measures the proportion of people who have had the infection at some unspecified time in the future, no longer the proportion who’re presently inflamed).
