Vaccines and persons who have had Covid19 - Few pertinent clarifications:
✅ Should a Covid survivor wait for a specific timeframe after recovery, to take the vaccine?
There is no specific guideline in India on this. As a matter of abundant caution, we recommend...
1/5
....taking the vaccine shot atleast 30 days after diagnosis or 15 days after recovery.
While Covid survivors will have an element of natural immunity, we strongly urge them to take the vaccine for more targeted immunity.
2/5
✅ If a person tests positive AFTER the first dose and BEFORE the second dose, can the 2nd vaccine dose be taken?
Yes, the 2nd dose can be taken. Wait till you recover. US CDC recommends the 2nd dose to be taken after the person has recovered from Covid19.
3/5
✅ If a person has symptoms of Covid19 (but not tested to confirm it), can he/she take the vaccine?
In case of symptoms, we strongly recommend to take a Covid19 test before taking the vaccine. If you are Covid +ve, wait till after recovery to take the vaccine.
4/5
✅ I am hearing cases of persons catching Covid19 even after taking the vaccine. Is it normal?
One can get infected even after taking both doses of vaccine. Vaccines play a role in reducing severity of infection, reducing probability of hospitalisation/fatality.

While we hear and see distressing news on the extreme crunch of medical resources, here is a SILVER LINING:
📣 The vast majority of those who get infected will recover through treatment at home.
Here is a short thread to help you navigate home treatment 👇
1/n
📌 When should I get tested?
(a) Within 2 to 3 days of having Covid19 symptoms. Test slots and reports are getting delayed across cities now, so plan in advance. Do not hesitate.
(b) Came in contact with a Covid19 +ve person: Test 5 days after last contact.
2/n
📌 Not getting a slot for RT-PCR tests and I have symptoms. What should I do?
Consult a doctor. Do not delay getting treatment due to delay in test results. Doctors can advise medication based on symptoms, additional blood tests, medical condition etc.

The effect of election campaigns in spike of Covid19 cases is best shown in the case of Kerala.
After a prolonged spike, cases were decreasing over Feb and early March 2021 in KL. TPR had dropped to around 4%.
Then, tests inexplicably dropped in the last 2 weeks of March.
1/4
The case trajectory started to take a swift turn immediately after April 6th, the date of voting.
✅ Testing started to move up and with it, so did daily cases. Testing > 1L now.
✅ From a 7 day avg. TPR of 5.9% on April 6, 7 day TPR has spiked to 17% as of yesterday.
2/4
✅ Active cases that were just short of 30k on April 6th, has now shot 6 times to 1.18L as of yesterday.
📣 The decreasing trajectory of cases in KL through Feb 2021 and subsequent increase immediately following the election campaign, directly points to the role played....
On reporting Covid19 deaths - The reported, differently reported and unreported:
Over the past weeks, we've seen multiple reports on differing number of Covid19 deaths.
While we continue to report the official numbers, here are some observations we've made along the way 👇
1/7
📌 Delay in reporting deaths: Skimming through detailed data on deaths released by limited number of states, shows that the reporting of deaths is delayed by days or even weeks. Eg. here is the KA bulletin of 19/04. Take a look at the date of death column.
2/7
📌 Deaths due to non-Covid reasons: Are all deaths of Covid19 +ve persons counted as a Covid19 death? Not in all cases. Few states periodically report deaths due to non-Covid reasons. This is usually determined by a committee that evaluates the cause of death.
3/7
The dangerous spike in weekly TPR over last 2 weeks: Test Positivity Rate (TPR) has jumped to alarming levels across multiple states/UTs this week.
Take a look at the attached analysis that compares TPR between 4th - 10th April and 11th to 17th April 👇
1/5
Notable observations:
✅ CG has recorded a TPR of 29% this week, implying every 3rd person being tested is turning positive.
✅ MH has a high TPR of 24.7% this week, but is the only major state to have shown a decline in weekly TPR compared to last week.
2/5
✅ GA with 23.7% and MP with 19.9%, tails CG and MH wrt TPR this week.
✅ UP has shown a high % increase in weekly TPR, from a low 3.85% from 4 - 10 April to 9.8% from 11 - 17 April. In the same period DL moved from 6.7% to 16.27%.

Why are we advised to maintain 6 feet distance for safety? Is there a chance to catch Covid19 even if one is more than 6ft away from an infected person? Why is wearing masks critical?
We explore these questions in this short thread.
1/n
There are 4 main modes of transmission of respiratory viruses:
✅ Contact: Spread through direct contact with an infected person.
✅ Formite: Spread through touching surfaces/objects that carry the virus.
✅ Droplet: Spread through larger droplets exhaled by the person.
2/n
✅ Airborne: Spread through smaller droplets that remain suspended in the air over longer distances.
📌 Why 6ft distance?
Respiratory 'droplets' are larger particles that contain the virus. Droplet transmission happens in close proximity, generally within about 6ft.

Our data team has been hustling on the vaccination data side. Some challenges we've been grappling with:
✅ Multiple data sources - (a) MoHFW/PIB and (b) CoWIN APIs. Primary source?
✅ Data differences between the 2 sources.
So, we have some updates. Read on 👇
1/4
✅ We are tracking CoWIN and MoHFW/PIB updates separately now.
✅ CoWIN data, though behind MoHFW numbers, gives us a richer set of data points to track.
📣 In a significant development, we are now tracking DISTRICT VACCINATION data.
Source - CoWIN APIs.
