Is Fever Screening A Good Way to Test COVID-19?

Published

With the lockdown being lifted one by one slowly across the globe, norms such as social distancing, sanitization of places, wearing masks, fever screening are put into place to prevent contracting the virus.

Fever screening is increasingly used to admit people into hospitals, work areas, railway stations, shops, schools, colleges, etc.

However, fever screening does not necessarily be suitable for testing the COVID-19. There are some fundamental physiological and clinical reasons to back this up.

Fever is only a reflex reaction of the body to counter the entry of a microbe into our body. By increasing the temperature of the body, the body becomes defensive to the infection of the virus. On such a condition, we take antipyretics like paracetamol t increase blood flow and sweating, which helps in bringing back the average body temperature.

Fever screening should be done by measuring the core temperature of the body. This is only possible when you put the thermometer in your mouth or rectum.

But Infrared thermometers and thermal cameras are not suitable for measuring the core temperature. They are used for measuring only the surface temperature, i.e., the skin’s temperature and the inner eye temperature.

The temperature of the skin changes with change in environment, body activities, etc. for example, when the temperature is hot outside or when you exercise, your skin will seem warm with the temperature above the core temperature. Similarly, when it is winter, your skin temperature will be below core temperature.

Besides, when you have a fever, your forehead skin temperature will be lower than the core temperature, because the warm blood is kept away from the surface of the skin. Hence, thermal camera screening may be misleading, giving false positive and false negative test reports. It will lead to a waste of time and money and also lead to a rapid spread in some cases.

Therefore, using infrared thermometers and thermal cameras is not reliable.

There are asymptomatic patients, and also every fever does not mean an infection of COVID-19. Besides, consuming antipyretics may suppress the fever and avoid detection by the thermal cameras.

Hence fever screening is not a proper measure to test for the virus.

Thermal cameras were introduced in airports and railway ports during the breakdown of the 2002/3 Severe Acute Respiratory Syndrome (SARS) pandemic. But they failed miserably in preventing the spread of the viral infection due to medical and technological reasons.

Difference Between PTSD and Other Mental Ailments

Published

on

By

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

Published

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.
