5 ways people could transmit the coronavirus — from respiratory droplets to semen — ranked in order of risk

5 ways people could transmit the coronavirus — from respiratory droplets to semen — ranked in order of risk. The coronavirus has one main mode of transmission: respiratory droplets that leave a person's mouth or nose when they sneeze, cough, or talk. Studies have also found virus particles in the air as aerosols, as well as in feces and semen, but those pose less of a transmission threat. Coronavirus particles have been found in spit, mucus, poop, semen, floating through the air, and on various surfaces, like doorknobs and packages. But your chances of getting sick after coming into contact with the virus in these different situations vary. Here are the five ways we know the coronavirus can spread, and how risky each one is for you.

GENETICS AND PIG PRODUCTIVITY.

Improving genetic lines not only improves production but it creates disease free/resistant lines that maintains herd health and ensures profitability.A lot of pig producers sort and select breeds that will be stable in their environment and produce optimally,this they often do by importing breeding stocks or crossing various lines to come up with that that is suitable for their environment. A pig breeding network in Thai is producing genetic lines that are suitable and adaptable to Asian countries; The siam pigs run by Dr Sakchai Topanurak, Chulalongkorn University and major driving force behind SiamPigs. The goal of SiamPigs' is not only to improve production performance, but also to solve endemic and chronic herd health problems. This concept was borne out of the fact that Western pig breeds do not always come fully prepared for the Asian reality as they are full of various pathogens and different market needs,the need to select genetic lines that are resistant to disease and yielding higher lean meat percentages. The operations of breeding systems ensures a nucleus herd is free from diseases. Genetics from a high health breeding nucleus will subsequently be distributed to a production herd. Breeders lower in the breeding pyramid of course always try to keep their production herds as free from diseases as a nucleus herd would be – and also try to maintain similar high health standards, e.g. by applying strict bio security measures. This is done to enable the pigs to perform to their full genetic potential so that they can deliver effective and competitive products. SiamPigs, established in Thailand, is a network of pig producers using improved genetics, disease tolerant and disease resistant pigs as a tool. The group's goal is not only to improve production performance, but also to solve endemic and chronic herd health problems. Many pig farms have successfully reduced the risk of infection from outside the farm by applying a model that revolves around the principle of 'one nucleus, one farm' . SiamPigs developed its own breeds – Duroc line 929, Large White line 7788, Landrace line 4701 and Siam Kurobuta, with the productivity of the network's members being on par with the world's top producers. Farms in the network vary in size, starting from 400 to more than 10,000 sows. The network covers more than 100 farms in Thailand, with over 250,000 sows using breeding stock and semen developed by SiamPigs.

CALVES UNDERGO GENETIC EDITING TO PREVENT GROWTH OF HORNS.

The two calves that grace a muddy pen on the UC Davis campus will never grow horns typical of their breed. Instead, they’ll always sport soft hair on the parts of their heads where hard mounds normally emerge. The calves were designed in a petri dish at a Minnesota-based genetics lab, with the goal of making them easier to pack into pens and trucks without the nuisance of their horns taking up valuable space. Their offspring may also lack horns, and generations of hornless cows could follow, potentially saving the dairy and cattle industry millions of dollars, said Alison Van Eenennaam, a geneticist at UC Davis’ College of Agriculture and Environmental Sciences who worked with the Minnesota lab Recombinetics. This first-of-a-kind result of a process called genetic editing is a test run that’s expected to deeply impact the cattle and dairy industry and the entire food supply, Van Eenennaam said. It’s also part of a flurry of research looking at how to make cattle easier to maintain, transport and turned into food. The research has raised concerns among some farmers and animal-rights activists who warn of the health and ethical risks of consuming genetically modified food, but so far, that hasn’t stopped the research drive. At UC Davis, animal geneticist Pablo Juan Ross has been trying to perfect a technique developed a decade ago but now gaining more acceptance to design cattle that produce only male offspring.“Males grow faster than females, and in beef production they are more desirable,” Ross said. Another project uses stem cells to produce a clone animal, Ross said. Genetic editing could also help design cows that are less prone to pneumonia, which would reduce their need for antibiotics.Van Eenennaam is keen on using word processing as an analogy to describe the differences between genetic editing and engineering. She likens genetic editing to changing the spelling of a word within a document and genetic engineering to pasting in a word from a completely different document.“You’re not bringing in something foreign ... like introducing a protein from a tomato into a fish, which is what is associated in genetic engineering,” she said. The two dairy calves had a precise section of DNA responsible for horn growth was knocked out and replaced with a precise section from a cow that does not produce that trait. Many cattle varieties do not grow horns, including Angus cattle. With dairy cattle – both male and female – horns are a given, and the animals are dehorned soon after they’re born.Once the cows are sexually mature, Van Eenennaam will collect semen from the bulls to inseminate horned cows – the route by which most cows are impregnated in the cattle and dairy industry. The plan is to track the calves’ growth and development and see whether the two faithfully transmit the hornless trait to their offspring.“The odds are 100 percent if Mendelian genetics holds true,” she said.She added that it’s not clear whether other, unexpected effects of editing will appear. If successful, it will allow the industry to bypass decades of breeding for polled, or hornless, cows. At the University of Missouri, researchers focus on genetically modifying pigs to remove genetic traits for maladies such as retinitis pigmentosa, hemophilia and cystic fibrosis, said Randall Prather, an animal geneticist at the school.

EBOLA COMPLICATIONS!!!

. Ebola survivors have been noted to have complications ,usually relating to vision.The major complications are loss of vision, redness of eyes, , swollen eyes, pain and severe sensitivity to light. This is a pointer that the virus has a residual bank in some organs exhibiting various signs and probably a point of new infection. The virus is known to be present in semen of survivors, indicating some grey areas in the Ebola saga .Read the story of 2 survivors here;http://www.livescience.com/52902-ebola-survivor-eye-problems-sacra.html

EBOLA RESURGENCE IN LIBERIA.

The deadly Ebola virus has reared its ugly head again in Liberia just when the country was to be pronounced EBOLA FREE. The latest victim a 44-year old woman died on 27/3/2015, her boyfriend was an Ebola survivor indicating that sexual transmission is a route of infection of the Ebola virus. Research has shown traces of Ebola virus in semen of survivors for at least 82 days after onset of symptoms ,to this end the W.H.O has advised Ebola survivors to abstain from sex during a 90- day period following recovery. The deputy health minister and head of the Ebola response team; Tolbert Nyenswah reiterated the stand of W.H.O and suggested that survivors go a step further until the the pathway of transmission is better understood. He suggested that Ebola survivors consider use of condoms for all sexual acts beyond 3 months. The Ebola virus has been linked to non-human primates such as monkeys and apes, the fruit bats has also been linked as a reservoir host. It has been documented that hunting in deep forest for wild animals(bush meat) and bats ,subsequent preparation and consumption is a major route of infection with the Ebola virus.The management of the sick in terms of cleaning vomitus, diarrhoea and other body fluids is responsible for spread.The burial rites and community -based burial ceremonies has further propagated the spread of the virus across the borders. The contamination of bedding, clothing and surfaces also contribute to spread of virus. The symptoms include fever,vomiting,diarrhoea and hemorrhaging .The bleeding is from all orifices, the diarrhoea and vomitus are also blood tinged. The envelope on the RNA virus is easily disrupted by washing with soap and water,hence hand washing is advocated. The use of alcohol based hand sanitizers has also been proven to inactivate the virus. The use of bleach to decontaminate surfaces,floors and drains is very effective for killing the virus. COMPLACENCY has been identified as the major cause of new cases of Ebola, it will be of paramount importance to be alert and be proactive. KEEP WASHING HANDS,WASH FLOORS/SURFACES WITH BLEACH.VISIT AN HOSPITAL IF YOU HAVE ANY OF THE EBOLA SYMPTOMS AND REPORT TO HEALTH AUTHORITIES IF YOUVE HAD CONTACT WITH PERSON WITH EBOLA,OR HAVE VISITED COUNTRIES WITH EBOLA CASES.
