India is witnessing an alarming surge in cases in the past few days. The second wave is spreading much, much faster than the first.
Experts believe the surge is partly fuelled by the new strains of the coronavirus, including a more infectious homegrown variant. The laxity in preventive measures, coupled with new variants, has resulted in a nationwide crisis.
Here’s a guide to help you tide over the 2nd wave:
WHEN TO TEST
On having symptoms:
Symptoms include fever, loss of smell and taste, body ache, chills, breathlessness.
The New symptoms reported include pink eyes, and hearing impairment, loose motions.
Close contact with COVID Positive patient:
If you were close to 6 feet for a total of 15 minutes or more with a confirmed COVID-19 patient
WHEN NOT TO TEST
If two weeks have passed after taking both doses of vaccine and if you have no symptoms.
WHICH TEST IS TO BE DONE
RT-PCR is the gold standard.
Rapid antigen test (RAT) gives an instant report. If RAT is positive, Covid is confirmed. But if RAT is negative and still there are symptoms, go for RT-PCR.
CT VALUE & CT SCORE
CT value in RT-PCR is Cycle Threshold Value, a marker for the viral load in a patient.
The lower the CT value, the higher the severity.
Doctors ask for a CT scan of the chest of some patients. Here, the higher the CT score, the higher the severity of the infection.
WHAT ARE THE STAGES OF CORONAVIRUS INFECTION
Asymptomatic, Home quarantine or isolation wards Patients are without any clinical symptoms, and chest scan is normal.
They may have a mild fever, fatigue, myalgia, cough, runny nose, sore throat, sneezing, nausea, vomiting, abdominal pain, or .diarrhea
Stage II (a)
Isolation wards/Hospital/ICU Condition
Moderate but frequent fever, cough, chest CT with lesions.
Stage II (b)
ICU Condition: Severe pneumonia with SpO2 < 92%.
ICU Condition: Critical, acute respiratory distress syndrome (ARDS), shock, heart failure, coagulation dysfunction, and acute kidney injury (AKI).
PREVENTION IS BETTER
Therapies for Covid are experimental only
No drug has been officially approved to treat Covid-19; hence prevention is the best way.
Wear masks, wash hands and maintain physical distancing
