A few weeks ago, one of my friends had a sore throat, occasional cough and he felt mildly feverish. He went to a doctor.
While the physician diagnosed it as a case of pharyngitis, he advised my friend to undergo a PCR test for COVID-19. (That's almost the norm now.) The test returned a negative result.
With medication, his condition improved and he resumed his normal routine.
A few days ago, the occasional cough returned.
So uncertain are our days and lives now that the seeming indications of some sort of problem with the respiratory tract sent the alarm bells ringing in the family, resulting in discussions on the need to call on a doctor again.
But my friend fended off the suggestions, citing lack of any other symptoms like fever or throat pain.
Don't take anything lightly these days, came the chorus of warning.
His nephew who is a doctor in the US got roped into the discussions and he asked his uncle to get a blood test done.
The results indicated two parameters above normal. Sensing something wrong, the doctor asked his uncle to get a CT scan of the lungs done.
The results came negative for COVID-19. But the doctor and his pulmonologist colleague found in the images of the lungs indications of very mild coronavirus infection.
Not leaving anything to chance, my friend is now under medication for COVID-19 and has isolated himself at home, with no symptoms other than an occasional dry cough.
He found his predicament very strange -- no COVID-19, but there is COVID-19!
This sums up the situation right now in India. Uncertainty, doubts, anxiety.
Lack of any clarity on how the virus -- which seems to have a mind of its own -- behaves is only making matters worse.
CT SCAN
People -- who have tested negative but are suspected to be infected, because they have some symptoms -- are asked to get a CT scan of the lungs done. This is a trend that has started this year.
The proponents say a swab test result could be inaccurate because the annoying process of taking the samples from the throat and nasal tract makes the person move back resulting in the collection of an inadequate amount of sample.
They say if there is an infection, there will be tell-tale signs in the lungs which the scan unmistakably captures.
However, the exposure of the body to radiation isn't advisable, and doctors have been warning against indiscriminate use of CT scan to detect COVID-19.
But radiologists and many general practitioners feel the benefits outweigh the risk.
LOCKDOWN
Prime Minister Narendra Modi this year resisted demands -- from even Anthony Fauci -- for a national lockdown. Instead, he left the decision to individual state governments, saying the incidence of infection isn't uniform across the country.
Now almost all the states in India have some form of lockdown in place. And as a result of that, the numbers are steadily declining.
Here in Bengaluru, the lockdown was earlier scheduled to be lifted today. But it has now been extended for another two weeks, till June 7.
That's the only thing that is certain.
