Tech-assisted COVID-19 tracking is having some issues

Privacy advocates warn that the danger of creating new government surveillance powers for the pandemic could lead to much bigger problems in the future.

Harnessing today's technology to the task of fighting the coronavirus pandemic is turning out to be more complicated than it first appeared.

The first U.S. states that rolled out smartphone apps for tracing the contacts of COVID-19 patients are dealing with technical glitches and a general lack of interest by their residents. A second wave of tech-assisted pandemic surveillance tools is on its way, this time with the imprimatur of tech giants Apple and Google. But those face their own issues, among them potential accuracy issues and the fact that they won't share any information with governments that could help track the spread of the illness.

Contact tracing is a pillar of infection control. It's traditionally conducted by trained public health workers who interview those who may have been exposed, then urge them to get tested and isolate themselves. Some estimates call for as many as 300,000 U.S. workers to do the work effectively, but so far those efforts have lagged.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
