As scientists race to develop vaccines and treatments for coronavirus there's one drug that's been getting a lot of attention the drug is 'Remdesivir' The Food and Drug Administration (FDA) has granted emergency use authorisation to use it to treat the coronavirus  Remdesivir is an antiviral drug that was originally meant to fight the Ebola virus. But it was so ineffective that it was eventually shelved. However, despite its initial failure, remdesivir was later shown to be effective against both SARS (Severe acute respiratory syndrome) and MERS (Middle East respiratory syndrome) and now being tested in clinical trials as potential treatment against coronavirus COVID-19.  Remdesivir is currently the word's best hope for treating coronavirus COVID-19. But it's not a silver bullet. Remdesivir doesn't cure coronavirus. But the experimental drug, which may speed up recovery from a coronavirus infection, is currently the best treatment we have against a COVID-19 ...

It is normal to feel stressed, anxious or have lots of worries right now. We are bound to be thinking about the COVID-19 which cause coronavirus disease and what may happen. When it reaches a point where our stress and worry is impacting upon our dail life, stopping us sleeping, or feels intolerable even with the current situation, it can feel particular stressful as we do not know exactly how, or when, things may change. We cannot say for sure when the things will be stabilise and if we, or those we care about, may be personally affected.  We may even do things we would normally do, to try feel more control and safe, like panic buying items in case they become unavailable. Which then makes them unavailable for other and passes the anxiety to others. This can all keep us locked in a cycle of stress, worry and tension. The good news is there are helpful things we can do to manage worry, feeling uncertain and break a cycle  What is the Stress  In a medical and biological co...

Testing for diseases is important because in most cases the quicker you can diagnose someone better their chance of recovery. This is the particular case for cancer where early detection and accurate diagnosis can ensure people are given the most effective treatment as quickly as possible. For coronavirus, testing serves to identify people who are infected or who have been infected with the virus in past. There are following types of test for coronavirus A PCR swab test to find out whether you currently have coronavirus An antibody blood test to find out whether you have previously had coronavirus and may have some degree of immunity The New Saliva test    PCR Swab test:  PCR (Polymerase chain reaction) in this test a swab of the nose or thorat is taken and sent to the lab. This test used to check virus genetic material. PCR is also widely used test to detect genetic material from cancer cells obtained from a biopsy.  While a PCR test for diseases such as coronavirus...

Coronavirus (COVID-19) Treatment The most common symptoms of COVID-19 Coronavirus are fever, coughing, and breathing problems. Unless you have severe symptoms, you can mostly treat COVID-19 at home, the way you treat cold and flu. Most people recover from coronavirus COVID-19 without the need for hospital care.  Scientists are trying to make new medicines and test some existing drugs to see whether they can treat COVID-19. In the meantime, there are a number of things that can relieve symptoms, both at home and at the hospital.  What experts say treat yourself at home if you have mild symptoms  Experts say there are a number of supplies you can buy now to prepare to take care of yourself at home if you have mild symptoms for COVID-19 Among your grocery items should be fresh fruit and vegetables as well as canned goods with long shelf lives  Among the medical supplies should be a thermometer, cough medicine, tissue,zinc, and vitamin c.

SARS-CoV-2(Severe acute respiratory syndrome coronavirus 2), which is refer to as coronavirus, cause coronavirus disease 19 (COVID-19). The Centres for Disease Control and prevention (CDC) states the virus that causes COVID-19 spreads mainly between people who are in close contact with one anther. The virus can be contracted from Respiratory droplets produced when an infected person coughs or sneezes or by touching a surface that has the virus on it and then touching their face.  People can take the following everyday action to protect themselves and others from thic COVID-19  Hand Washing:  Regular hand washing is one of the main ways to help prevent the transmission of coronavirus  People should use plenty of soap and water to wash their hands for at least 20 seconds,  especially after: Traveling on public transport Being in public place  Coughing  Sneezing  Blowing their nose  If a person is not able to use soap and water, they can use a h...

A vaccine trail is a clinical trial that aims at establishing the safety and efficacy of a vaccine prior to it being licensed. Developing vaccines requires special consideration because vaccines  Are given to healthy individuals to prevent disease and help contribute to heath and well-being of society as a whole  Demand a high safety threshold to achieve approval  Are highly complex substance derived from living materials that require specific manufacturing process  Require specialized testing to assure quality and safety in all vaccine distributed   How are new vaccines Developed The development cycle of a vaccine includes  Exploratory stage  Pre-clinical stage  Clinical development  Regulatory review and approval  Manufacturing  Quality control  What are clinical trials Clinical trials are research studies involving human volunteers that often evaluate the safety and efficacy of preventative measures or treatment product...
