Normal viruses infect cells in order to take advantage of cellular mechanisms to reproduce themselves. A class of viruses known as "retroviruses" have a slightly peculiar mechanism to achieve this - they synthesise a special enzyme called "reverse transcriptase", which translates their own RNA into DNA which is incorporated into the host cell's genome. The ...

The Washington Times article you linked itself contains multiple quotes pouring cold water on the notion that the Wuhan coronavirus was produced by the Chinese government. Rutgers University microbiologist Richard Ebright: “at this point there’s no reason to harbor suspicions” that the lab may be linked to the virus outbreak. Bar Ilan University ...

Latest study confirms that the chances increase due to a variety of factors diminishing immune response, at least in mouse cells: Temperature-dependent innate defense against the common cold virus limits viral replication at warm temperature in mouse airway cells (Ellen F. Foxman, doi: 10.1073/pnas.1411030112) ... To gain insight into the mechanism of ...

According to the World Health Organization: More than two thirds (70%) of all malaria deaths occur in this age group. In 2015, about 305,000 African children died before their fifth birthdays. This data was used by an African organization africacheck.org when trying to estimate the number of malaria deaths in children under 5 in Africa: Then, using a ...

You are quoting the WHO and then say 'no citation is provided'. The WHO is the source. They are well equipped to research these kind of questions and it is part of their job to issue recommendations and rules about these kind of things. So receiving a package from China is safe, source the WHO. On the other hand, travelling to Wuhan in person is currently ...

Summary Based on current evidence, the Zika virus appears to be the likely cause of Brazil's microcephaly outbreak. There is limited evidence to support pyriproxyfen as a cause, but further, more specific, studies are required to test this hypothesis. Zika Virus There are several strands of evidence which point to the Zika virus as the likely (but not ...

I wish to add to the above answer. Approximately 9% of the genome is viral in origin, but current research suggests there is less of 'you' than there are other viral related sequences. Here is a very nice listing of the percentages of various genetic elements within the human genome: http://sandwalk.blogspot.com/2008/02/theme-genomes-junk-dna.html Although ...

It is too early to tell. We do not know its origin. We have neither any evidence for nor anything against this claim. 1. First of all: While the question 'as is' misrepresents the origin of the claim: The Washington Times article just says this: Coronavirus may have originated in lab linked to China's biowarfare program That does not say 'the lab made ...

Yes, there are two ways in which untreated rabies can develop, one, affecting roughly 70% of untreated people, is called "furious rabies" and leads to dramatic changes in behaviour. From the WHO (my bold): The incubation period for rabies is typically 1–3 months, but may vary from <1 week to >1 year. The initial symptoms of rabies are fever and often ...

The CDC now say the Zika virus is the cause. On April 13, 2016, a new report was published by doctors from the CDC in the New England Journal of Medicine. Zika Virus and Birth Defects — Reviewing the Evidence for Causality, DOI: 10.1056/NEJMsr1604338 This review examined the available evidence and concluded: On the basis of this review, we conclude ...

The Tencent screenshot is almost certainly a hoax, for the simple reason that such screenshots are extremely easy to fake. For example, here's how easy it is to get a "screenshot" of the New York Times showing millions of people dead in Japan. First, we search for coronavirus and pick a random article. Here's a good one: Next, hit F12 to open up developer ...

Take a look at this live map of the virus. The calculation is based on the number of deaths, divided by the number of confirmed cases (multiplied by 100 to get it as a percent%). As of February 3rd 2020, that would be 362 / 17405 * 100 ~= 2.08% fatality rate.

As has been stated, there is no evidence that such is the origin. From the other direction, the phylogeny of the virus seems to indicate that it diverged from an existing virus in bats. And, that ancestral virus is also ancestral to several other viruses in bats and humans, including SARS. Though SARS seems to have followed a path from bats, through civets, ...

The question assumes that organisms came before viruses. From the latest attempts to deduce what happened many years ago, a current belief is that viruses and organisms had a single originating organism. This means that in terms of the current species, the two likely already were subjects of Endogenosymbiosis, where one didn't necessarily directly come ...
