RESUMO

With the roll-out of worlds largest vaccine drive for Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) by Government of India on January 16 2021, India has targeted to vaccinate its entire population by the end of year 2021. Struggling with vaccine procurement and production earlier, India came up with these hurdles but the Indian population still did not seem to be mobilizing swiftly towards vaccination centers. With the initial hesitancy, as soon as the vaccination started to speedup, India was hit severely by the second wave. The severe second wave has slowed down the vaccination pace and also it was one of the major contributing factor of vaccine hesitancy. To understand the nature of vaccine hesitancy and factors underlying it, we conducted an extensive online and offline surveys in Varanasi and adjoining regions using structured questions. Majority of respondents though were students (0.633), respondents from other occupations such as government officials (0.10) were also included in the study. We observed several intriguing opinions on our eleven questions. It is interesting to note that the majority of the people (0.75) relied on fake news and did not take COVID-19 seriously. Most importantly, we noticed that a substantial proportion of respondents (relative frequency 0.151; mean age 24.8 years) reported that they are still not interested in vaccination. People who have neither been vaccinated nor have ever been infected may become the medium for spreading the virus and creating new variants. This could also lead to a resistant variant of the vaccine in the future. We expect that this extensive survey may help the government to upgrade their vaccination policies for COVID-19 in North India.

RESUMO

PurposeDue to surge in COVID cases during the second wave of the COVID pandemic, the healthcare system collapsed in India with shortage of hospital beds, injudicious use of steroids and other immunomodulators, and poor glycaemic monitoring among a population with pre-existing risk of diabetes. Fungal epidemic was announced amid COVID pandemic with several cases of COVID-associated mucormycosis and aspergillosis being reported. But, there is no data regarding mixed fungal infections in COVID patients. Materials and MethodsThe study presented a series of ten consecutive cases with dual invasive molds in patients infected with SARS-CoV-2. Among patients hospitalized with the diagnosis of COVID in May 2021 at a tertiary care center in North India, ten microbiologically confirmed dual/mixed COVID-associated mucor-aspergillosis (CAMA) were evaluated. ResultsAll patients were diabetics with the majority having severe COVID pneumonia (6/10, 60%) either on admission or in the past one month, whilst two were each of moderate (20%) and mild (20%) categories of COVID. The patients were managed with amphotericin-B along with surgical intervention. In this case series, 70% of all CAMA (Rhizopus arrhizus with Aspergillus flavus in seven and Aspergillus fumigatus in three patients) patients survived, connoting the critical importance of a high index of clinical suspicion and accurate microbiological diagnosis for managing invasive molds. ConclusionsMixed fungal infections i.e. CAMA during COVID and post-COVID periods may be an emerging disease. This outbreak is seen particularly in such patients with uncontrolled diabetes, on steroids, or cocktail therapy, or living in unhygienic environments.We believe that our findings would help gain a better insight into the risk and progression of invasive fungal mixed infections among COVID patients and thus play a pivotal role in diagnosing, classifying, and implementing an effective management strategy for treating similar cases in the future.

RESUMO

The COVID-19 pandemic has resulted several waves of infection in many countries worldwide. The large variations in case fatality ratio among different geographical regions suggests that the human susceptibility against this virus varies substantially. Several studies from different parts of the world showed a significant association of ABO blood group and COVID-19 susceptibility. It was shown that individuals with blood group O are at the lower risk of coronavirus infection. To establish the association of ABO blood group in SARS-CoV-2 susceptibility, we for the first time analysed SARS-CoV-2 neutralising antibodies as well as blood groups among 509 random individuals from three major districts of Eastern Uttar Pradesh region of India.. Interestingly, we found neutralising antibodies in significantly higher percentage of people with blood group AB (0.36) followed by B (0.31), A (0.22) and lowest in people with blood group O (0.11). This indicates that people with blood group AB are at comparatively higher risk of infection than other blood groups. Further, in line to previous reports we too observed that people with blood group O have significantly decreased risk of SARS-CoV-2 infection. Thus, among the asymptomatic SARS-CoV-2 infected individuals with blood group AB has highest, whilst blood group O has lowest risk of infection.

RESUMO

Infection born by Coronavirus SARS-CoV-2 has swept the world within a time of a few months. It has created a devastating effect on humanity with social and economic depression. Europe and America were the hardest hit continents. India has also lost lives, making the country fourth most deadly worldwide. However, the infection and death rate per million and the case fatality ratio in India were substantially lower than in many developed nations. Several factors have been proposed including genetics. One of the important facts is that a large chunk of Indian population is asymptomatic to the SARS-CoV-2 infection. Thus, the real infection in India is much higher than the reported number of cases. Therefore, the majority of people are already immune in the country. To understand the dynamics of real infection as well as the level of immunity against SARS-CoV-2, we have performed antibody testing (serosurveillance) in the urban region of fourteen Indian districts encompassing six states. In our survey, the seroprevalence frequency varied between 0.01-0.48, suggesting high variability of viral transmission between states. We also found out that the cases reported by the government were several fold lower than the real incidence of infection. This discrepancy is mainly driven by the higher number of asymptomatic cases. Overall, we suggest that with the high level of immunity developed against SARS-CoV-2 in the majority of the districts, the case fatality rate of second wave in India will be minor than first wave.
