Meteorological factors and Covid-19 incidence in 310 regions across the world

This study analyzed l data from 311 regions across 116 countries with reported cases of COVID-19 by March 12, 2020, and found that temperature, humidity, and wind speed were inversely associated with the incidence rate of Covid-19. This means that it is likely that as temperature, humidity and wind speed increase the spread of COVID-19 decreases.

Mobility traces and spreading of COVID-19

The authors have built human mobility models, for which they are experts, and attach a virus infection dynamics to it. This results in a virus spreading dynamics model. The preliminary model shows that complete lockdown works. About 10 days after lockdown, the infection dynamics die down in the model. Infections in public transport play an important role, they say. The simulations say that complete removal of infections at child care, primary schools, workplaces and during leisure activities will not be enough to sufficiently slow down the infection dynamics.

A mathematical model of COVID-19 transmission between frontliners and the general public | medRxiv

This study formulates a conceptual mathematical model on the transmission dynamics of COVID-19 between the frontliners (e.g. healthcare workers, customer service and retail personnel, food service crews) and the general public. The take-home message of this preliminary model is that everyone in the community, whether a frontliner or not, should be protected or should implement preventive measures to avoid being infected.

Role of Chloroquine and Hydroxychloroquine in the Treatment of COVID-19 Infection- A Systematic Literature Review | medRxiv

This is a systematic literature review summarizing the available evidence regarding the role of chloroquine in treating coronavirus infection. It says there is theoretical, experimental, preclinical and clinical evidence of the effectiveness of chloroquine in patients affected with COVID-19. There is adequate evidence of drug safety from the long-time clinical use of chloroquine and hydroxychloroquine in other indications. More data from ongoing and future trials will add more insight into the role of chloroquine and hydroxychloroquine in COVID-19 infection it concludes.

Association of Cardiac Injury With Mortality in Hospitalized Patients With COVID-19 in Wuhan, China

New study in JAMA Cardiology says COVID-19 can not only be deadly for people with existing heart conditions, but it can also cause cardiac injury for people without pre-existing heart conditions. The study looked at 416 COVID-19 patients hospitalized in Wuhan, China and found that 19.7% suffered a cardiac injury, which put them at higher risk for a fatal version of Coronavirus.

Genetic variants of COVID-19

There are several genetic strains of COVID-19 circulating around the world. Information is found on NextStrain, an online resource for scientists that uses data from academic, independent and government laboratories all over the world to visually track the genomics of the SARS-CoV-2 virus. It currently represents genetic sequences of strains from 36 countries on six continents.

Physical interventions to interrupt or reduce the spread of respiratory viruses: systematic review

A wide-ranging study points out that simple public health measures seem to be highly effective at reducing the transmission of respiratory viruses. It recommends implementing the following interventions: frequent handwashing (with or without antiseptics), barrier measures (gloves, gowns, and masks), and isolation of people with suspected respiratory tract infections.

What is the evidence for loss of smell and loss of taste as a clinical feature of COVID-19?

The authors are of the opinion that evidence regarding the complete loss of smell, or anosmia and the loss of taste or dysgeusia in people who had no other symptoms but who tested positive for COVID-19 are mostly anecdotal and therefore should be treated as preliminary and with caution.

Loss of sense of smell as marker of COVID.pdf

A Statement from ENT UK at The Royal College of Surgeons of England, the association of ear, nose and throat physicians in the United Kingdom says a growing body of data from COVID-19 patients in several countries strongly suggests that “significant numbers” of those patients experienced the complete loss of smell known as anosmia as one of the disease’s symptoms.

Identifying SARS-CoV-2 related coronaviruses in Malayan pangolins

A new paper, 26 March, describes multiple lineages of pangolin coronavirus and their similarity to the SARS-CoV-2. A previous study had suggested that Pangolins could be intermediate hosts.  Although bats are likely reservoir hosts for SARS-CoV-2, this study says that pangolins should be considered as possible hosts in the emergence of novel coronaviruses and should be removed from wet markets to prevent zoonotic transmission. The study was done on Malayan pangolins (Manis javanica) seized in anti-smuggling operations in southern China. Pangolins are the world’s most trafficked animals.

The SARS, MERS and novel coronavirus (COVID-19) epidemics, the newest and biggest global health threats: what lessons have we learned?

This paper finds that Inadequate risk assessment regarding the urgency of the situation, and limited reporting on the virus within China has, in part, led to the rapid spread of COVID-19. Compared with SARS and MERS, COVID-19 has spread more rapidly, due in part to increased globalization and the focus of the epidemic. The conclusion is that we did not learn from the two prior epidemics of coronavirus and were ill-prepared to deal with the challenges the COVID-19 epidemic has posed. Future research should attempt to address the uses and implications of the internet of things (IoT) technologies for mapping the spread of infection.

We shouldn’t worry when a virus mutates during disease outbreaks

Mutation. The word naturally conjures fears of unexpected and freakish changes. Ill-informed discussions of mutations thrive during virus outbreaks, including the ongoing spread of SARS-CoV-2. In reality, mutations are a natural part of the virus life cycle and rarely impact outbreaks dramatically say virologists writing in the journal Nature Microbiology.

Are viruses alive?

 Viruses are kind of mysterious – there is debate on whether on not they are “alive”.  At a basic level, viruses are proteins and genetic material that survive and replicate within their environment, inside another life form. In the absence of their host, viruses are unable to replicate and many are unable to survive for long outside the host. Therefore, if they cannot survive independently, can they be defined as being ‘alive’? Taking opposing views, two microbiologists discuss how viruses fit with the concept of being ‘alive’ and how they should be defined.

WHO launches global megatrial of the four most promising coronavirus treatments

An article from the publishers of Science on 22 March on WHO megatrials. WHO is focusing on what it says are the four most promising therapies: an experimental antiviral compound called remdesivir; the malaria medications chloroquine and hydroxychloroquine; a combination of two HIV drugs, lopinavir, and ritonavir; and that same combination plus interferon-beta, an immune system messenger that can help cripple viruses.

Twitter thread on Chloroquine (CQ) and Hydroxychloroquine (HCQ) by Dr. Gaetan Burgio

Unusually, we include a Twitter feed here as it represents a good analysis of the efficacy of the antimalarial drug chloroquine as a treatment for COVID-19. It is from Dr. Gaetan Burgio, a geneticist at the Australian National University who dug into the available & published data and reveals that as of this date the evidence remains anecdotal and a clinical trial is incomplete and not following scientific rigour. More research is needed.

How to stop future pandemics in 3 easy steps

While many of us are social distancing and self-quarantining, we have a lot of time to wonder, how did we get in this coronavirus mess in the first place? The answer is a zoonotic disease – a disease that can leap from animal to human. In order to prevent future pandemics, we need to change our relationship with wildlife. So what does that mean exactly?

1. Stop wildlife trade
2. Stop wildlife consumption
3. Stop destroying nature

Decisions on how to apply quarantine should be based on the best available evidence. This paper reviews the psychological impact of quarantine using three electronic databases. Results show that in situations where quarantine is deemed necessary, officials should quarantine individuals for no longer than required, provide a clear rationale for quarantine and information about protocols, and ensure sufficient supplies are provided.
