COVID-19: The new saliva test promises to be cheaper and faster

Dr B. J. C. Perera

Extensive and rapid result oriented testing to detect coronavirus infections is a vital key during the on-going pandemic. Detecting an infection early would help to contain the spread of the virus and help save lives. Many countries around the world have been exasperated over testing shortages and delays for a considerable time.
A new saliva-based test for COVID-19 could offer a fast and inexpensive solution to millions of people. This new laboratory diagnostic test has been developed by researchers at the Yale School of Public Health in the USA. In a paper published on 04th August 2020 in the preprint server medRxiv, a team from Yale documented the new tool called ‘SalivaDirect’. Another team, comprising many of the same researchers, had earlier this year detailed that saliva could be collected in any sterile container and that it remained mostly stable, without the need for special tubes or preservatives.
Until now, detecting the novel coronavirus SARS-CoV-2 involved the reverse transcription-polymerase chain reaction test. This “RT-PCR” test is conducted by collecting a sample from the back of a person’s nose or mouth. While effective, the nasopharyngeal swabbing is unpleasant and the test is not cheap. There is also a limit to the amount of COVID-19 testing that can be done through this method.
This is where the new ‘SalivaDirect test’ could be a real game-changer as it promises to be faster, less expensive and more flexible. With saliva being quick and easy to collect, this test could indeed be a significant advance in COVID-19 diagnostics. Up to now, the results have shown that SalivaDirect is highly sensitive and produces similar results as nasopharyngeal swabbing. Now, further tests are being conducted to see if the method can be successful as a test for asymptomatic individuals, too. Compared to nasopharyngeal swabs, researchers found a “high agreement” of more than 94 per cent in detecting true positives between the two methods.
The SalivaDirect test doesn’t require a special swab or collection device. It can also be used with reagents from various vendors. The researchers had simplified the test so that it only costs a couple of dollars. The cost per sample could be as low as $1.29 to a high of $4.37, with the addition of a saliva collection aids.
A key step in the traditional COVID-19 testing includes extracting the virus’s RNA after the sample is collected before it can be detected by sensitive PCR-based methods. SalivaDirect removes the extraction step and replaces it with something very simple. An enzyme is added and the mixture is heated up. This process removes the most expensive step which is the most time consuming one which requires the most skill as well. The new test can run approximately 90 samples in fewer than three hours and has the potential to scale higher in bigger laboratories having automation. What’s even more encouraging is that Yale is offering SalivaDirect’s protocol open source. This means that researchers around the world can take and modify the method for use in their own labs depending on the resources they have.
Moreover, the saliva-based test is safer, too. In the traditional method, when the swab is inserted into the back of the throat, it often leads to a cough or a sneeze. Thus, there’s always a risk of the discharge of droplets from the person carrying the virus. With SalivaDirect, that risk is minimized as only the saliva will be collected. It can be further reduced if the sample is self-collected under the supervision of a healthcare professional. Thus far, the only condition with SalivaDirect is that the sample collected should be clear liquid saliva. This effectively means that the technique may not be suitable for hospitalized COVID-19 patients because their saliva samples may contain blood or mucus that can affect the final reading. Barring this, SalivaDirect does seem to be a good, low-cost, and effective method for rapid detection of COVID-19.
The United States of America Food and Drug Administration (FDA) has now given Emergency Use Authorization to SalivaDirect. The low-cost and non-invasive procedure requires minimal processing and retains much of the accuracy of traditional nasopharyngeal swabs. FDA Commissioner Stephen Hahn says in a press release announcing the emergency use authorization, “Providing this type of flexibility for processing saliva samples to test for COVID-19 infection is ground-breaking in terms of efficiency and avoiding shortages of crucial test components like reagents”.
SalivaDirect has already been used voluntarily by several teams of professional basketball players. People such as coaches, staff, and players from both the National Basketball Association (NBA) and the National Basketball Players Association (NBPA) of the United States of America began voluntarily using the test in June, and their participation was central in gaining FDA Emergency Use Authorization.

Kashmir terror attack underscores need for South Asian stability and amity

The most urgent need for the South Asian region right now, in the wake of the cold-blooded killing by gunmen of nearly 30 local tourists in Indian-administered Kashmir two days back, is the initiation of measures that could ensure regional stability and peace. The state actors that matter most in this situation are India and Pakistan and it would be in the best interests of the region for both countries to stringently refrain from succumbing to knee-jerk reactions in the face of any perceived provocations arising from the bloodshed.
The consequences for the countries concerned and the region could be grave if the terror incident leads to stepped-up friction and hostility between India and Pakistan. Some hardline elements in India, for instance, are on record in the international media as calling on the Indian state to initiate tough military action against Pakistan for the Kashmiri terror in question and a positive response to such urgings could even lead to a new India-Pakistan war.
Those wishing South Asia well are likely to advocate maximum restraint by both states and call for negotiations by them to avert any military stand-offs and conflicts that could prove counter-productive for all quarters concerned. This columnist lends his pen to such advocacy.
Right now in Sri Lanka, nationalistic elements in the country’s South in particular are splitting hairs over an MoU relating to security cooperation Sri Lanka has signed with India. Essentially, the main line of speculation among these sections is that Sri Lanka is coming under the suzerainty of India, so to speak, in the security sphere and would be under its dictates in the handling of its security interests. In the process, these nationalistic sections are giving fresh life to the deep-seated anti-India phobia among sections of the Sri Lankan public. The eventual result will be heightened, irrational hostility towards India among vulnerable, unenlightened Sri Lankans.
Nothing new will be said if the point is made that such irrational fears with respect to India are particularly marked among India’s smaller neighbouring states and their publics. Needless to say, collective fears of this kind only lead to perpetually strained relations between India and her neighbours, resulting in regional disunity, which, of course would not be in South Asia’s best interests.
SAARC is seen as ‘dead’ by some sections in South Asia and its present dysfunctional nature seems to give credence to this belief. Continued friction between India and Pakistan is seen as playing a major role in such inner paralysis and this is, no doubt, the main causative factor in SARRC’s current seeming ineffectiveness.
However, the widespread anti-India phobia referred to needs to be factored in as playing a role in SAARC’s lack of dynamism and ‘life’ as well. If democratic governments go some distance in exorcising such anti-Indianism from their people’s psyches, some progress could be made in restoring SAARC to ‘life’ and the latter could then play a constructive role in defusing India-Pakistan tensions.
It does not follow that if SAARC was ‘alive and well’, security related incidents of the kind that were witnessed in India-administered Kashmir recently would not occur. This is far from being the case, but if SAARC was fully operational, the states concerned would be in possession of the means and channels of resolving the issues that flow from such crises with greater amicability and mutual accommodation.
Accordingly, the South Asian Eight would be acting in their interests by seeking to restore SAARC back to ‘life’. An essential task in this process is the elimination of mutual fear and suspicion among the Eight and the states concerned need to do all that they could to eliminate any fixations and phobias that the countries have in relation to each other.
It does not follow from the foregoing that the SAARC Eight should not broad base their relations and pull back from fostering beneficial ties with extra-regional countries and groupings that have a bearing on their best interests. On the contrary, each SAARC country’s ties need to be wide-ranging and based on the principle that each such state would be a friend to all countries and an enemy of none as long as the latter are well-meaning.
The foregoing sharp focus on SAARC and its fortunes is necessitated by the consideration that the developmental issues in particular facing the region are best resolved by the region itself on the basis of its multiple material and intellectual resources. The grouping should not only be revived but a revisit should also be made to its past programs; particularly those which related to intra-regional conflict resolution. Thus, talking to each other under a new visionary commitment to SAARC collective wellbeing is crucially needed.
On the question of ties with India, it should be perceived by the latter’s smaller neighbours that there is no getting away from the need to foster increasingly closer relations with India, today a number one global power.
This should not amount to these smaller neighbours surrendering their rights and sovereignty to India. Far from it. On the contrary these smaller states should seek to craft mutually beneficial ties with India. It is a question of these small states following a truly Non-aligned foreign policy and using their best diplomatic and political skills to structure their ties with India in a way that would be mutually beneficial. It is up to these neighbours to cultivate the skills needed to meet these major challenges.
Going ahead, it will be in South Asia’s best interests to get SAARC back on its feet once again. If this aim is pursued with visionary zeal and if SAARC amity is sealed once and for all intra-regional friction and enmities could be put to rest. What smaller states should avoid scrupulously is the pitting of extra-regional powers against India and Pakistan in their squabbles with either of the latter. This practice has been pivotal in bringing strife and contention into South Asia and in dividing the region against itself.
Accordingly, the principal challenge facing South Asia is to be imbued once again with the SAARC spirit. The latter spirit’s healing powers need to be made real and enduring. Thus will we have a region truly united in brotherhood and peace.

Perfect … and healthy

Got a few more beauty tips to give you … for a perfect complexion, or, let’s say, a healthy skin.
* Honey Face Mask:
Take a tablespoon of raw honey and then warm it up by rubbing it with your fingertips. Apply the warm honey all over your face. Let this natural mask stand for about 10 minutes and then wash it off gently with warm water.
* Coconut Milk Face Mask:
You need to squeeze coconut milk out of a grated raw coconut and apply this milk all over your face, including your lips.
(This will help you gain a glowing skin. It is one of the best natural tips for skin care)
* Orange, Lemon, and Yoghurt Moisturiser:
To prepare this moisturiser, you need a tablespoon of orange juice, a tablespoon of lemon juice and a cup of plain yoghurt.
Mix them together and apply the paste all over your face, leaving it as a mask for 10 to 15 minutes. Next, take a damp handkerchief and use it to clean your face.
(This moisturiser brightens the complexion of your skin)
* Cucumber and Lemon:
Apply equal parts of cucumber and lemon juice on your face before taking a bath. Allow it to sit for 10 minutes before rinsing it off. This natural face beauty tip will brighten your skin tone and lighten blemishes if used on a regular basis. The best aspect is that it is appropriate for all skin types!
* Healthy Diet:
Aside from the effective home remedies, there are certain other factors to consider for skin care – and the first of them is your diet. Without the right nutrients, your skin cannot reverse the damage it suffers every day.
Eat fruits that are high in vitamin C because they contain antioxidants.
Adjust your diet to get the right amount of protein and unsaturated fats, as well as fresh green vegetables. All of this provides the right amount of nutrients so your skin can heal and improve itself naturally.
* Sun Protection and Care:
Another thing to keep in mind is not to step out of your home without sunscreen, especially with this awful heat we are experiencing at the moment. The hard rays of the sun can do you more damage than you could ever imagine.
By the way, you can prepare your own sunscreen lotion with glycerin, cucumber juice and rose water. You can also keep this lotion in the fridge.
