Are self-tests for COVID-19 available?
If we get infected with an infectious disease, will we not want to protect our family and others from it? But, unless we know our disease status timely and reliably, how can we help prevent further infection transmission? How will we link up, and benefit from, health and clinical care pathways until we know that we are infected? When self-tests for COVID-19 are available, there is no excuse not to make them affordable and accessible to everyone without any further delay, so that these easy to use tests can complement the confirmatory RT-PCR tests and other diagnostics for those who need them – and serve as an entry point for health and clinical care pathways.
Global organizations and experts wrote an open letter to WHO to authorize and recommend the use of COVID-19 rapid antigen detection tests for self-testing
That is why more than one hundred global organizations and experts have issued an open letter calling upon the United Nations health agency (World Health Organization – WHO) to authorize and recommend the use of COVID-19 rapid antigen detection tests for self-testing in low- and middle-income nations. People should be able to know their COVID-19 status in a simple, cheap and non-discriminatory manner. Such information will help them to take prompt action to break the chain of onward infection transmission, and rapid linkage to the healthcare pathway will be another important outcome of this, argues this open letter that was issued towards the end of January 2022.
Why self-test for COVID-19?
More than 10 billion COVID-19 vaccine doses have been administered globally in a world of over 7 billion people. But more than 3 billion people have yet to receive even their first dose. Vaccine inequity has cost unnecessary human suffering and untimely deaths. Now, inequity in accessing self-tests is a looming danger we cannot, and must not, have to deal with if we are to deliver on the tall promise of health for all where “no one is left behind”.
85% of the global population lives in low- and middle-income nations yet only 40% of COVID-19 tests were done in these places. “The reported average per capita daily testing rate of high-income countries is nearly 10 times higher than that of middle-income countries and close to 100 times higher than that of low-income countries” reads the open letter.
In Africa alone, 85% of COVID-19 infections are going undetected according to WHO. This inequity in access to the diagnostic tools that trigger life-saving individual and public health measures is part of the same ‘medical apartheid’ that has plagued the rollout of COVID-19 vaccines, added the open letter.
Self-testing is a necessary tool to enable rapid linkage to care and initiation of outpatient treatment to prevent hospitalisation and death, especially among those at high risk of disease progression.
There is another reason why home self-tests are important to be made available, affordable, and accessible to all. A photograph published in news in early February 2022 shows ‘healthcare workers under police protection’ going door to door to conduct COVID-19 testing.
Noted infectious diseases expert Dr Ishwar Gilada is right in commenting on this news that “Looking here, people have been right in doing home self-tests using rapid antigen detection tests and the following self-quarantine if they were positive for COVID-19, without notifying to authorities! Who wants to be stigmatised in this way? Look at the health team without social distancing and posing [with the person being tested fully visible].”
We do not know if the health authorities and police (or media) took permission from the person, who is being tested in the photograph, to take and make the photo public, but we do know that such top-down approaches to infection control have been counterproductive for public health as well as for human rights.
Open letter calls upon WHO to issue self-testing guidelines
The open letter calls upon the WHO to expedite the finalisation and release of a self-testing guideline for SARS-CoV-2 infection that includes a strong recommendation in favour of widespread access to self-testing. It is believed that the Guideline Development Process of WHO is currently underway, due to which the open letter emphasises the urgency of WHO making an immediate statement in favour of this important tool for COVID-19 control in the interim.
Dr Ishwar Gilada, who was among the first doctors to begin HIV medical management when the first HIV infection case was diagnosed in India, said to CNS (Citizen News Service): “It is very important that home self-testing be made available to everyone. We need to empower and trust people as equal partners with dignity in the fight against COVID-19. I have not seen anyone who is ‘wanting to infect others. So this fear is unfounded. People will like to protect their families and others with who they come in contact, provided they know their COVID-19 status. We saw this approach work in rights-based health responses to control other infectious diseases.”
Self-testing has the capacity of greatly expanding the number of people who know that they have contracted COVID-19 and are likely to be infectious to others. Access to self-tests promises significant benefits, particularly in resource-limited and geographically remote settings that lack sufficient RT-PCR testing capacity. Even in areas with RT-PCR testing know-how, self-testing can increase uptake among marginalised populations who are less able and/ or likely to engage with the health system because of stigma, discrimination or unaffordability.
