Half the world at risk of malaria: WHO Of 243M Cases Across Globe In 2009, 863000 Died; Africa Accounts For 90% Of Infections
The news from the frontline is mixed on World Malaria Day today. While the UN affiliated World Health Organisation (WHO) and several private agencies are cautiously optimistic because of recent decline in reported malaria cases and an increased flow of funds for fighting malaria, others, including the leading health journal Lancet are pointing at the looming clouds of drug resistance and lack of suitable vaccine for this ancient killer disease.
Malaria, along with tuberculosis, continues to be one of the world’s most lethal diseases with half the world’s population — about 3.3 billion people — at risk from it, according to the latest World Malaria Report 2009, released by WHO last December. Over 243 million confirmed cases of malaria were reported from across the world, of which an estimated 863,000 died. The biggest burden of malaria is borne by Africa with nearly 90% of cases, most being children below 5 years.
In India, while there has been proportional reduction in the number of cases, the numbers are still huge. From over 2 million reported cases in 2000, confirmed malaria cases dropped to about 1.51 million in 2007, but then showed an upward tick in the next two years to reach 1.53 million in 2009, according to provisional estimates of National Vector Borne Diseases Control Programme of the health ministry.
Experts believe that these are gross underestimates because the reach of testing facilities is limited and large numbers are going unreported.
In the World Malaria Report, WHO director general Margaret Chan struck an optimistic note saying that global funding for fighting malaria had jumped from a commitment of $300 million in 2003 to $1.7 billion in 2009. As a result, coverage with insecticide treated nets (ITN) increased from 17% to 31% while population covered by indoor residual spraying of insecticide increased from 14 million to 59 million. Testing for malaria and treatment with the new artemisinin combination therapy (ACT) too has increased substantially.
In 2006, WHO issued new guidelines for tackling malaria that include mandatory testing before prescribing drugs. This is to prevent the growing threat of resistance of the malarial parasite to these drugs if given indiscriminately. Quinine based drugs have already gone out of favor because of widespread resistance to it.
In India too, one variety of malarial parasite was found to have developed resistance to chloroquine in 117 highly endemic districts of 7 North Eastern states and Andhra Pradesh, Chhatisgarh, Jharkhand, Madhya Pradesh and Orissa.
As the resilient malarial parasite battles it out with medical science across the world in a do or die battle, there are some ominous signs on the horizon. Starting with studies in Cambodia, and then from several pockets in other parts of the world, resistance to the new artemisinin based drugs has been reported. According to an editorial in Friday’s edition of Lancet, “There is currently no new drug class for treatment in advanced development”. In other words, if resistance to artemisinin spreads, like it did for chloroquine, the global fight against malaria would be lost.

4,443 malaria cases in Mewat since June – Sept 2016
A mid the din and hurt sentiments that the Haryana government's biryani policing generated in Mewat, a malaria threat sweeping through the district has gone virtually unnoticed and, going by the government's own figures, unchecked.
Since June, Mewat has recorded 4,443 cases of malaria, which accounts for two-thirds of the 6,695 cases reported across Haryana.Around 90% of the posts in Mewat's health department lying vacant. “The reason why we are unable to tackle this menace is because there are hardly any medical resources,“ said a health department official.
2017: cases decline by 24%

3 Million Fewer Cases Between 2016 And 2017
Marking significant progress in the fight against malaria, India recorded nearly 24% decline in cases in a year between 2016 and 2017, the only one among the 11 highest-burden countries to achieve so, says the latest World Malaria Report.
Deaths due to malaria have also dropped significantly to 194 in 2017 from 331 in the previous year, says the 2018 report. However, with 4% of global cases, India continues to account for the highest malaria burden outside sub-Saharan Africa.
“The 10 highest burden countries in Africa reported increase in cases of malaria in 2017 compared with 2016. Of these, Nigeria, Madagascar and Democratic Republic of Congo had the highest estimated increase, all more than half a million cases. In contrast, India reported 3 million fewer cases in the same period, a 24% decrease compared with 2016,” says the World Health Organisation report.
India plans to eliminate malaria by 2027, three years ahead of the global target and has also formulated an action plan.
According to latest figures available with the health ministry’s National Vector Borne Disease Control Programme, till September this year, 2,76,488 cases of malaria were reported in the country, whereas mortality declined to double digit at 29 deaths till two months ago.
Globally, there were an estimated 219 million cases of malaria in 2017, whereas deaths reached 4,35,000 in the same year. In India, three states — Odisha, Chhattisgarh and West Bengal, which account for a major burden of malaria cases — reported a substantial decrease.
2019: decline

WHO: Sharp dip in malaria cases in India in 2019
New Delhi:
India has made considerable progress in reducing its malaria burden and is the only high endemic country to have reported a decline of 17.6% in cases during 2019 as compared to the previous year, says the World Malaria Report 2020 by World Health Organisation. India also witnesses the largest absolute decline in WHO’s South-East Asia region, though it still accounted for 88% of malaria cases and 86% of related deaths in the region. In India, between 2000 and 2019, malaria cases dropped by over 83% to around 3.38 lakh, whereas deaths declined by 92%. Cases and fatalities have declined a significant 21.3% and 20%, respectively, in 2019 from a year ago. TNN
Malaria cases till Oct fell by 45% against last year’s count
Total number of malaria cases reported till October this year fell 45% year-on-year, the government said. States like Odisha, Chhattisgarh, Jharkhand, Meghalaya and MP together accounted for nearly 45.4% of total malaria cases in the country in 2019. They were also responsible for 63.6% malaria deaths.
The government intensified malaria elimination efforts with the launch of the National Framework for Malaria Elimination in 2016. It was followed by the national strategic plan for malaria elimination (2017-22), launched by health ministry in July 2017, which laid down strategies for next five years.
In 2019, global malaria cases stood at 229 million, an estimate that has remained unchanged over the last four years. The deaths from the disease have dropped slightly to around 4.09 lakh in 2019 compared to 4.11 lakh in 2018.
Judicial judgments
Death by mosquito is not insurable: SC
Krishnadas Rajagopal, March 26, 2019: The Hindu
National Insurance Limited argued that a mosquito bite cannot be classified as a ‘personal accident’ covered under the policy.
Is death by mosquito bite insurable as a ‘personal accident’? Well, not if the mosquito bit the insured person in the Republic of Mozambique, the Supreme Court held on Tuesday in a judgment.
The case concerns the death of a man, Debhashis Bhattacharjee, who died of multiple organ failure after being diagnosed with encephalitis malaria contracted from a mosquito bite he sustained while working in Mozambique in 2012.
His insurance policy covered personal accidents. Both the State and the National Consumer Dipsutes Redressal Commissions dismissed the plea made by the insurance company, National Insurance Limited, that the man died as a result of an infection. The company had argued that a mosquito bite cannot be classified as a ‘personal accident’ covered under the policy.
The insurance company, represented by advocate Madhavi Divan, said death due to malaria was a common occurrence in Mozambique. Ms Divan adverted to the World Health Organization’s World Malaria Report 2018, which showed that an estimated ten million cases of malaria in Mozambique and an estimated 14.7 thousand deaths in the year 2017.
A Bench led by Justice D.Y. Chandrachud disagreed with the conclusions of both the Consumer Disputes Commissions. In fact, the State Commission had held that it would be “rather silly” to call a sudden death due to mosquito bite in a foreign land a natural death and not an accident. The National Commission too had agreed that if the insurance company could cover events like snake bite, frost bite and dog bite then why not mosquito bites.
In his 16-page judgment, Justice Chandrachud acknowledged that being “bitten by a mosquito is an unforeseen eventuality”.
However, the mosquito bit Mr. Bhatacharjee in Mozambique, which according to World Health Organization has a population of 29.6 million people and accounts for five per cent of the cases of malaria globally.
Malaria is too common in Mozambique. “It is on record that one out of three people in Mozambique is afflicted with malaria. In light of these statistics, the illness of encephalitis malaria through a mosquito bite cannot be considered as an accident. It was neither unexpected nor unforeseen. It was not a peril insured against in the policy of accident insurance,” Justice Chandrachud set aside the decisions of the Consumer Disputes Commission.

`Malaria's P. vivax strain threat to India'
Sushmi Dey
A particular strain of malaria parasite, which was believed to be less fatal, is now causing high disease burden, latest assessment by the World Health Organization shows.
While asking India to strengthen its strategy for elimination of malaria, the agency said countries need to focus more on P.vivax, which was so far known as less fatal but as the latest data shows the risk from the parasite is increasing.
India, in particular has witnessed a huge growth in the number of malaria cases due to P.vivax. In 2013, there were an estimated 15.8 million symptomatic cases of P.vivax malaria globally . Out of this, two-thirds occurred in the south-east Asia region which includes India, according to a latest WHO report on control and elimination of P.vivax malaria.
Though, the report doesn't provide specific number of P.vivax cases found in India, WHO said in a statement that India is a major contributor to the cases found in south-east Asia.
Separately , the Union health ministry's assessment under the National Vector Borne Disease Control Programme shows that there is a slight dip in the malaria cases due to P. falciparum parasite, known to be more fatal. According to a health ministry official, over 50% of total malaria cases in India are triggered by P.vivax. “Our efforts so far focused on the most deadly P.falciparum malaria. We need to now broaden our strategy to include targeted interventions for P.vivax malaria, which is contributing to a large proportion of global malaria burden, mainly in the WHO south-east Asia region,“ said WHO regional director Poonam Khetrapal Singh. WHO is hosting a global malaria meet in New Delhi to address the rising threat of P.vivax.
