There are intensifying actions to combat the mosquito Aedes which is admittedly responsible for the transmission of diseases: chikungunya, dengue and zika. Among these dengue is a recurring problem that affects the entire world, especially the tropical areas. It is considered one of the world’s greatest public health problems by the World Health Organization, which estimates that approximately 390 million people get infected by this disease each year worldwide. In Brazil, since the first report of the disease in 80’s, dengue has continually occurred, alternating epidemic periods with peaks of increasing disease. Therefore, this study aims to assess the feasibility of using unmanned aerial vehicle, popularly known as drone, in aid of the dengue control program executed in Maringá - PR. In conclusion the use of this aircraft is feasible, since it is an economically attractive investment due to its low cost against the annual investment with manpower.

A simple, low-cost pyrene derivative containing a benzilmonohydrazone moiety has been exploited for the selective detection of Cu2+ by colorimetric, absorption, emission and bio-imaging methods. The sensitivity of the fluorescence based assay is 7.8 nM for Cu2+, which is far below the limit mentioned in the World Health Organization.

Abstract With a newly World Health Organization (WHO)–prequalified typhoid conjugate vaccine (TCV), Gavi funding for eligible countries, and a WHO policy recommendation for TCV use, now is the time for countries to introduce TCVs as part of an integrated typhoid control program, particularly in light of the increasing burden of antimicrobial resistance. Continued vaccine development efforts will lead to secure supply of low-cost vaccines, and ongoing vaccine studies will provide critical vaccine performance data and inform optimal deployment strategies, in both routine use and in outbreak settings. TCV programs should include thoughtful communication planning and community engagement to counter vaccine hesitancy.

We are in the middle of an unprecedented pandemic named COVID-19 by the World Health Organization (WHO) which is caused by a novel coronavirus. The novelty of the virus and its disease is so new that the entire world is experiencing its consequences on various aspects. The pandemic is still unfolding and creating some new patterns around us. Besides the buzzword, that is, the vaccine is far from our sight. So naturally, we have to look for existing solutions if they can be implemented until the vaccine arrives. From Hydroxychloroquine (HCQ) to Bacillus Calmette Guèrin (BCG) all are being used in trials whether they can be pre-vaccine medicine or not. The variable effect on individual sections of the population has to be studied to deliver a targeted response, especially in resource lacking countries. In addition to these medical problems like social distress and quarantine measures which are taking a toll on people's minds, another unwarranted problem of Infodemic has struck us. So, this paper will review the ongoing steps and challenges and how we can efficiently respond to them to conquer this pandemic.

: Severe Acute Respiratory Syndrome (SARS) aka SARS-CoV spread over southern China for the first time in 2002-2003 and history repeated again since last year and take away more than two million people so far. On March 11, 2020 COVID-19 outbreak was officially declared as pandemic by World Health Organization (WHO). Entire world united to fight back against this ultimate destruction. Around 90 vaccines are featured against SARS-CoV-2 and more than 300 active clinical trials are underway by several groups and individuals. So far, no drugs are currently approved that completely eliminates the deadly corona virus. The promising SARS-CoV-2 anti-viral drugs are favipiravir, remdesivir, lopinavir, ribavirin and avifavir. In this review, we have discussed the synthetic approaches elaborately made so far by different groups and chemical companies all around the world towards top three convincing anti-viral drugs against SARS-CoV-2 which are favipiravir, remdesivir and lopinavir.

Artemisinin Combination Therapies

Malaria is among the deadliest infectious diseases in the world caused by Plasmodium parasites. Due to the high complexity of the parasite’s life cycle, we partly depend on antimalarial drugs to fight this disease. However, the emergence of resistance, mainly by Plasmodium falciparum, has dethroned most of the antimalarials developed to date. Given recent reports of resistance to artemisinin combination therapies, first-line treatment currently recommended by the World Health Organization, in Western Cambodia and across the Greater Mekong sub-region, it seems very likely that artemisinin and its derivatives will follow the same path of other antimalarial drugs. Consequently, novel, safe and efficient antimalarial drugs are urgently needed. One fast and low-cost strategy to accelerate antimalarial development is by recycling classical pharmacophores. Quinacrine, an acridine-based compound and the first clinically tested synthetic antimalarial drug with potent blood schizonticide but serious side effects, has attracted attention due to its broad spectrum of biological activity. In this sense, the present review will focus on efforts made in the last 20 years for the development of more efficient, safer and affordable antimalarial compounds, through recycling the classical quinacrine drug.

As of late toward the finish of 2019, another illness was found in Wuhan, China. This illness was analyzed to be brought about by another kind of Covid and influenced nearly the entire world. Chinese scientists named this novel infection as 2019-nCov or Wuhan-Covid. Notwithstanding, to try not to misjudge the World Health Organization commotions it as COVID-19 infection while interfacing with the media COVID-19 is new internationally just as in India. This has upset peoples and group minds. There are different gossips and tidbits about the Covid in Indian culture which causes alarm in neighborhoods and people group minds. It is the need of society to know legends and realities about Covid to lessen the frenzy and make the correct preparatory moves for our security against the Covid. Subsequently, this article attempts to bring to the open fantasies and present current realities to the ordinary citizens. We have to confirm fantasies spreading through online media and keep our selves prepared with realities and be confident of what we know and do at this COVID 19 era at individual levels. Fitting these activities in individual minds across nations is bound to benefit the whole world.

The endemicity of malaria in tropical areas of the world persists, especially in countries south of Saharan Africa. The efforts and concerns invested by the World Health Organization and other health agencies to eradicate malaria are commendable. However, in spite of all these efforts, the loss in economic and human resources continues. In a previous report, the long-term health effects of insecticide-impregnated bednet (IIBN) use were highlighted with the expectation of attracting serious thoughts and further research on the issue. This present paper is an update on that expectation. Results from a comprehensive literature search show that not much work has been done on the effects of long-term exposure to IIBNs in combating malarial infection. The efficacy of IIBNs is not in question. What is in question is whether long-term exposure to IIBNs have any health effects. The aims and outcomes of the research found in the literature on the subject to date seem to support only the efficacy of the temporal use of plain bednets, but not the use of IIBNs, and do not tell much about the long-term effects of IIBN exposure. All pesticides are toxic by nature and present risks of adverse effects. While there is agreement that IIBNs can be effective in reducing malarial morbidity and mortality under field trials, a number of factors relating to their long-term-exposure health effects have yet to be determined. Further reliable research projects are recommended urgently. However, some of the anticipated behavioral effects caused by insecticidal use will be avoided by the use of untreated nets instead.
