WHO REPORTS ON CORONA VIRUS, Important Updates you must know & follow :
This all information is taken by the official account of WHO. In this era of social media, we never know what is true or what is not. We must look at this original WHO Report so that nothing could misguide us.
WHO REPORTS AT PREPAREDNESS AND RESPONSE OF COVID-19 :
- To view all technical guidance documents regarding COVID-19, please go to this webpage.
- WHO has developed interim guidance for laboratory diagnosis, advice on the use of masks during home care and
in health care settings in the context of the novel coronavirus (2019-nCoV) outbreak, clinical management,
infection prevention and control in health care settings, home care for patients with suspected novel
coronavirus, risk communication and community engagement and Global Surveillance for human infection with
novel coronavirus (2019-nCoV).
- WHO is working closely with International Air Transport Association (IATA) and have jointly developed a
guidance document to provide advice to cabin crew and airport workers, based on country queries. The
guidance can be found on the IATA webpage.
- WHO has been in regular and direct contact with Member States where cases have been reported. WHO is also
informing other countries about the situation and providing support as requested.
- WHO is working with its networks of researchers and other experts to coordinate global work on surveillance,
epidemiology, mathematical modelling, diagnostics and virology, clinical care and treatment, infection
prevention and control, and risk communication. WHO has issued interim guidance for countries, which are
- WHO has prepared a disease commodity package that includes an essential list of biomedical equipment,
medicines and supplies necessary to care for patients with 2019-nCoV.
- WHO has provided recommendations to reduce risk of transmission from animals to humans.
- WHO has published an updated advice for international traffic in relation to the outbreak of the novel
- WHO has activated the R&D blueprint to accelerate diagnostics, vaccines, and therapeutics.
- OpenWHO is an interactive, web-based, knowledge-transfer platform offering online courses to improve the
response to health emergencies. COVID-19 courses can be found here. Specifically, WHO has developed online
courses on the following topics: A general introduction to emerging respiratory viruses, including novel
coronaviruses (available in Arabic, Chinese, English, French, Russian, Spanish, Hindi, Persian, Portuguese,
Serbian, and Turkish); Clinical Care for Severe Acute Respiratory Infections (available in English, French, Russian,
and Vietnamese); Health and safety briefing for respiratory diseases – ePROTECT (available in English, French,
Russian, Indonesian, and Portuguese); Infection Prevention and Control for Novel Coronavirus (COVID-19)
(available in Chinese, English, French, Russian, Spanish, Indonesian, Italian, Japanese, Portuguese, and Serbian);
and COVID-19 Operational Planning Guidelines and COVID-19 Partners Platform to support country
preparedness and response (available in English and coming soon in additional languages).
- WHO is providing guidance on early investigations, which are critical in an outbreak of a new virus. The data collected from the protocols can be used to refine recommendations for surveillance and case definitions, to characterize the key epidemiological transmission features of COVID-19, help understand spread, severity, spectrum of disease, impact on the community and to inform operational models for implementation of
countermeasures such as case isolation, contact tracing and isolation. Several protocols are available here. One such protocol is for the investigation of early COVID-19 cases and contacts (the “First Few X (FFX) Cases and contact investigation protocol for 2019-novel coronavirus (2019-nCoV) infection”). The protocol is designed to gain an early understanding of the key clinical, epidemiological and virological characteristics of the first cases of COVID-19 infection detected in any individual country, to inform the development and updating of public health guidance to manage cases and reduce the potential spread and impact of infection.
RECOMMENDATIONS AND ADVICE FOR THE PUBLIC BY WHO :
If you are not in an area where COVID-19 is spreading or have not travelled from an area where COVID-19 is
spreading or have not been in contact with an infected patient, your risk of infection is low. It is understandable that you may feel anxious about the outbreak. Get the facts from reliable sources to help you accurately determine your risks so that you can take reasonable precautions (see Frequently Asked Questions). Seek guidance from WHO, your healthcare provider, your national public health authority or your employer for accurate information on COVID-19 and whether COVID-19 is circulating where you live. It is important to be informed of the situation and take appropriate measures to protect yourself and your family (see Protection measures for everyone).
If you are in an area where there are cases of COVID-19 you need to take the risk of infection seriously. Follow the advice of WHO and guidance issued by national and local health authorities. For most people, COVID-19 infection will cause mild illness however, it can make some people very ill and, in some people, it can be fatal. Older people, and those with pre-existing medical conditions (such as cardiovascular disease, chronic respiratory disease or diabetes) are at risk for severe disease.
Coronavirus disease (COVID-19) advice for the public issued by WHO :
Wash your hands frequently
Regularly and thoroughly clean your hands with an alcohol-based hand rub or wash them with soap and water.
Washing your hands with soap and water or using alcohol-based hand rub kills viruses that may be on your hands.
Maintain social distancing
Maintain at least 1 metre (3 feet) distance between yourself and anyone who is coughing or sneezing.
Why? When someone coughs or sneezes they spray small liquid droplets from their nose or mouth which may contain virus. If you are too close, you can breathe in the droplets, including the COVID-19 virus if the person coughing has the disease.
Stay informed and follow advice given by your healthcare provider
Stay informed on the latest developments about COVID-19. Follow advice given by your healthcare provider, your national and local public health authority or your employer on how to protect yourself and others from COVID-19.
Why? National and local authorities will have the most up to date information on whether COVID-19 is spreading in your area. They are best placed to advise on what people in your area should be doing to protect themselves.
Does Tea Cure COVID-19?
It is a well-known fact that improved immunity is the only way to fight against COVID-19 infection as there are no drugs or vaccines discovered to destroy the virus. Doctors have been treating coronavirus patients worldwide by improving immunity and fighting the virus. Similarly, improved immunity also helps prevent viral infection. Hence, immunity boosters have been playing a crucial role in the pandemic, as insisted by the World Health Organization (WHO).
Recently, a rumor has it that drinking tea does cure the coronavirus. It buzzes that the Chinese doctor Dr. Li Wenliang, who had warned in the initial stage of the COVID-19 epidemic, also found that tea cures the virus. Later it was observed that the tea consists of chemicals that kill the virus in the cells engineered in vitro experiments. But according to the Zhejiang Provincial Center for Disease Control and Prevention, in vitro tests are not enough to prove that tea helps in curing coronavirus.
According to research in the Indian Institute of Technology (IIT), Delhi, scientists have found that tea actually helps in treating coronavirus. They state that consuming Myrrh with tea is a potential cure as Myrrh and tea are effective in preventing the growth of an essential protein in the COVID-19 virus. These two plants have the power to reduce the strength of the virus, as concluded by the study of Kusuma School of Biological Sciences (KSBS) on fifty-one herbal plants on clones of the coronavirus protein.
However, clinical trials are required to come to a conclusion, says Prof. Ashok Kumar Patel, leader of the research, IIT.
Benefits of Green Tea
According to scientists, green tea is rich in anti-bacterial properties and also helps in controlling cholesterol and Blood Pressure (BP). Also, black tea is an excellent immunity booster.
Difference Between PTSD and Other Mental Ailments
Post-Traumatic Stress Disorder is the reflex action of mind against traumas in a person’s life. The trauma may be physical or sexual abuse, accidents, natural or human-made catastrophes, war combats, terrorism, loss of a loved one, or any other incident that had deeply affected the person’s psychology. It is common in people who have undergone any such disturbing events, but it is often confused with other mental ailments like depression, anxiety, substance abuse, etc.
Women are twice likely than men to develop PTSD, and children do too. Though a person may recover from PTSD at one point, he may continue to suffer from depression and anxiety for months and sometimes even years.
To treat a disorder, it is necessary that we find its origin first. So, it is essential that we identify PTSD accurately. And PTSD is often difficult to diagnose.
How to Differentiate Between PTSD and Other Mental Disorders?
Overlapping symptoms is one of the primary reasons for this confusion. For instance, a person may suffer from depression and anxiety at once or depression and PTSD at once. Sometimes, the symptoms of the two different conditions may even co-exist. Consider a person who is already suffering from depression. If he/she undergoes a traumatic incident, apart from PTSD, depression deepens. Though there is no particular cause of depression, PTSD follows any traumatic events like rape, witnessing a crime, etc.
So, here is a list of common symptoms of PTSD that will help you figure out if a person is suffering from PTSD:
It is not necessary that the symptoms start showing up right after the incident. It may take months or even years after the traumatic incident.
There are three significant symptoms:
- Recurring memories of the incident that affected you, like flashbacks or over voices, nightmares and reliving the incident through theses type of physical or emotional reactions.
- Emotional numbness and avoiding talking about the incident or anything or anyone related to it.
- Feeling on edge, jumpy, easily scared or angered, difficulty in sleeping and concentrating.
You may be down on yourself. You shall feel:
- Persistently negative moods
- Hopeless, depressed,
- Self-destructive like drinking too much alcohol or drive too fast
- Detached from people and social interactions
- easily startled or frightened, or you might always be on guard for danger
- Have trouble sleeping due to fear of nightmares that make you relive the memory
Some overlapping symptoms of PTSD and other mental illnesses are Insomnia, Lack of focus, lack of interest, Irritability, Detachment from people, and the world.
If you feel or notice a person feeling the symptoms mentioned above for four weeks or longer, then it is impulsive that you consult a psychiatrist for professional advice, diagnosis, and treatment.
Researchers suspect that SARS-CoV-2 might be evolving since 2013
Researchers of the University of Calgary in Canada, suspect that the novel Coronavirus (SARS-CoV-2) might be in evolution among humans since around 2013. But it might not be the same strain that is causing this COVID-19 pandemic.
Six strains of Coronavirus wereCoronavirus commonly prevalent among animals. But the seventh strain is an anonymous strain that is wreaking havoc in the form of COVID-19 and causing a global catastrophe by infecting the human population in the mass.
While scientists throughout the world are working hard to figure out the virus, its effects, origin, and cure, the World Health Assembly had passed a resolution to find the source of the strain.
There are multiple theories of origin. One, the virus got transferred from an animal to a human. Two, it was artificially developed in a laboratory in china for some medical reasons. However, studies rule out this possibility by saying the origin is natural and not human-made.
Recently, a team of researchers at the University of Calgary in Canada say that the SARS-CoV-2 might have been in circulation among humans beginning from as early as 2013. However, it would not be the same strain responsible for the pandemic. They have submitted their report at the Biorxiv, but the findings of the research have not yet been reviewed by the peers.
It is upon the survival mechanism of the viruses that they keep evolving with the changes with the host organism, i.e., if the host evolves, the virus evolves too. So, when the virus jumped from an animal to human, it would nave underwent genetic modification that would produce a new strain of the same virus, only that now it is more powerful and infective. This implies the virus that had mild or no effect on the animal host may have enormous impacts on the human host. For example, the strain of the virus in the bats did not affect the bats, as their immune system was equipped to co-exist with the virus. However, once it jumped hosts, we obviously tend to fall sick.
What does the Canadian Study say?
The study was conducted by the University of Calgary in Canada between 30 December 2019 to 20 March 2020, when they collected about 479 genome sequences of the novel Coronavirus to study its phylogeny. Phylogeny is the study of the evolutionary development of the virus and its relation to other closely related viruses.
The researchers examined the spike protein of the strain of SARS-CoV-2 and how it attaches to the receptors in the human body. This attachment of the novel Coronavirus and the receptors to the human cells determine how the virus invades the healthy tissues. They found 16 variant strains of the virus and about 11 missense mutations out of the 479 genomes. A mutation is when a single nucleotide change makes the DNA/RNA code for a different protein. Thus, some of them gave rise to a separate phylogenetic tree.
Another one of their findings included that the SARS-CoV-2 might be a combination of both bat virus and the pangolin virus. The study found that the genome of novel coronavirus matched 96 percent with that of bat virus and 90 percent with that of the pangolin virus. They predict that this variant might have developed due to a co-infection in the host.
To trace the origin of this novel Coronavirus, the researchers created an ancestral sequence of the receptor-binding domain (RBD) of the spike protein of SARS-CoV-2 and labeled it N1. RBD is the part of the spike protein that actually binds with the receptor. The animal virus, which is the common ancestor, was labeled N0.
With what they discovered in the experiment, the scientists concluded that the binding affinity of SARS-CoV-2 might not be a determinant of its infectivity. Further, they predict that there should be some other factors that increased their infectivity in humans. The main conclusion is that the ancestral virus could have been infecting humans too, but with unnoticeable symptoms.
