Kerala has been a model state when it comes to controlling the spread of infectious diseases. Strong surveillance as well as healthcare systems managed to catch and curb the spread of Nipah virus and the Zika virus. But this may have been also why the state is now struggling with the novel coronavirus disease (COVID-19) pandemic.
The average number of daily new cases reached a low of 11,000 around the last week of June, 2021, and it has since been rising, albeit slowly, over the past two weeks. At the same time, the number of cases elsewhere in the country has been falling after a major second-wave peak in the first week of May.
With over 30,000 new Covid cases for the second day in a row. In the last 24 hours, the state recorded 30,007 cases, 18,997 recoveries and 162 deaths. With this, the number of active cases has gone up to 1,81,209 while Test Positivity Rate (TPR) stands at 18.03% thereby contributing more to the COVID tally compared to the majority of other states.
Reasons for the increased spread of COVID-19 in Kerala in recent times
- Kerala’s population is ageing and older people are more at risk of death.
- Faint rural urban divide which acted as a barrier in many states are absent in case of kerala
- Improper home isolation due to the linear pattern of houses.
- Non-communicable diseases (NCDs) such as cardiovascular disease, diabetes, cancer and chronic obstructive pulmonary disease have become the major causes of death and disability in Kerala in pre COVID times. This high prevalence of Non Communicable diseases helps in increased spread of the virus thereby increasing the rate of infections
- Better health system, which leads to better detection due to increased hospitalisation rates.
- Kerala detected one in every six cases of Covid-19. Compared to the nationwide number of one in every 33, which can be attributed to the high numbers of infection rates.
- Lack of active surveillance and contact tracing as pointed out by the centre’s team
- Increased population density of 859 persons per km2; which is three times as densely settled as the rest of India and extended life expectancy (or, ageing)
- Kerala’s sero-positivity is substantially less than the national average. Kerala’s figure is 43 per cent compared to the national figure of 68 per cent. This means that well over 50% susceptible population are vulnerable with the prevalence of 90% of highly infectious Delta variant in the state
- The Delta variant hit Kerala later than the rest of the country. Therefore, it is spreading at a rate similar to that at which it earlier spread in the rest of the country
- Lifting lockdown restrictions too soon and allowing festivals and public celebrations to take place despite a raging second wave and a high TPR rate.
Way Forward:
Adequate intervention in geographical areas having higher infection, through measures such as contact tracing, vaccination drives and Covid appropriate behaviour. The possibility of placing night curfew in areas of high positivity and weekend lockdowns should be considered. The efficacy of vaccines are being questioned due to the rise of infections in doubly vaccinated individuals hence measures including stringent lockdowns should be considered to curb the spread of the virus.
