Kerala has been reporting fresh cases of the novel coronavirus in single digits for the past few days, a flattening of a deadly curve by measures that included early detection, aggressive testing and contact tracing, and a 28-day quarantine period — double that prescribed by the WHO. And underlying it all and making it possible was a robust public health system.

From one infection on January 30 to 378 on April 13 and two deaths so far, the state has seen 198 people recover. It recorded its highest cases in a day (39) on March 27, and the lowest on March 19 (1). On April 12, it was just two cases. It realized early on the potential lethality of a curve arcing sharply upward.

#January18: State Health Department issued a Covid-19 alert

Began to screen passengers arriving from abroad, initially from the cradle of the virulent spread: China. International arrivals were given a health card in which they had to list their travel details and health condition. All the state’s five airports were linked to ambulances and emergency response in district hospitals. Over the next week, it set up district control rooms, started procuring masks, gloves, other personal protection equipment (PPE) and medicines. It ordered district hospitals to designate isolation wards.

#February4: Declared Covid-19 threat, a state disaster

Contact tracing was meticulous. Manual surveillance, from January 30 to March 8, began with interviewing individual patients and working backward to people with whom they had been in touch.

#March9: Introduced Spatio-temporal Mapping

It was after a family of three came didn’t report their travel to Italy. This involved a detailed flowchart that depicted the date, time and movement of each affected person, based on call details and CCTV footage.

#28Days Strict Home quarantine was Imposed

12,470 were in home quarantine on March 16; this rose to 1,22,676 people on April 11. Each person in home quarantine, for 28 days instead of the recommended 14, received an average of 2 to 3 calls daily from authorities. About 16,000 teams ensured those in home quarantine stayed home.

#April 2, 14,989 samples had been sent for testing, of which 13,802 came out negative. From April 1 to 13, the state conducted 227 tests per million people for its population of 3.4 crore.

Kerala also kept its doctors safe. A three-tier system was implemented at all government medical college hospitals. Doctors were split into three teams. The first worked on Covid-19 cases and in isolation wards. The second attended outpatient cases and the emergency department. The third stayed home on leave, prepared to deploy if the need arose.

The lockdown showed results in Kerala. The state had reported 109 cases on March 24, a day before the lockdown, and was at that point the worst-hit. But, as the lockdown wore on, it almost flattened the curve, bringing the increase in cases per day down to just about 10% by the end of the first week. Since April 3, it’s been between 3% and 4%.

It is worth debating & considering shifting the migrant workers FROM METRO CITIES to their native villages, provided the shifting is done by taking following steps carefully: 1. Arranging special trains & buses, and 2. Quarantining them, may be in the same trains, for 2 to 4 weeks before they reach their native villages, and obviously taking subsequent necessary steps in case they show evidence of COVID19 infection during the quarantine period or later. Reasons why this shifting may be beneficial & necessary: 1. They admittedly live in congested rooms (& areas) sometimes even 10 to 12 of them per room (which are even without toilet facilities in the room). If any of them gets infected with COVID19, the infection can spread quickly to create havoc in the thickly populated congested rooms (& areas). 2. They survive generally on daily wages which daily wages are almost absent in these COVID19 days, because of lockdown in metro cities. They may be able to work in farms in villages after the suggested quarantine period is over for them.... Read more
