Abstract
Malaria is a highly debilitating vector-borne parasitic infection which has been known to be mortal and
morbid to human beings for centuries now. As of today, the success rate of effective control strategies is
less; however there have been several riveting developments. These include: 1. A global incidence of
decrease in malaria cases; 2. The development of several non-malaria transmissible transgenic
mosquitoes and 3. The launch of the vaccine has been a game changer as it is now being given to
children with the success rate being high. In this review, we discuss if the current control strategies in
place and the launch of the vaccine and its speculated success in children has become/been a game
changer. Our take on the coevolution of parasites and vector can be the answer to the questions above.
We highlight that parasites and vectors have evolved together for millions of years now, and to break this
liaison will not be as easy.

1. Introduction
Malaria is a vector-borne disease caused by the parasites Plasmodium falciparum (P.
falciparum) and Plasmodium malariae (P. malariae). It is transmitted by the vector female
Anopheles mosquito during blood-feeding
[5]
. Malaria causes a sizable impact on
socioeconomic well-being of the human population in the tropical and subtropics
[4]
. Malaria
infection results in a wide variety of symptoms like absence or very mild fever, sometimes
severe that may result in death. As stated by the World Malaria Report (WMR) 2021, the
caseload of malaria is said to have increased from 227 million in 2019 to 241 million in 2020
[62]
. The malaria-linked mortality has reduced from 148 per 100,000 cases to 56 per 100,000
cases between 2000 and 2019. However, in 2020 it rose to 60 and decreased again to 58 in
2021. These numbers are within the range of yearly fluctuations and coinciding with the global
Covid-19 pandemic. This rise might also be because of changes in the norms for calculating
cause-of-death based upon the revelations suggesting an updated series of cause-specific
mortality for neonates and children in 2000 to 2019
[46]
. This is contrary to several reports
stating decline in Malaria cases and mortality
[61]
. In this review we discuss recent
developments in malaria control and whether the century-long battle against malaria is finally
over.
2. Recent developments in malaria management
Current focus in malaria control involves continual development, upgradation of existing
drugs and design of novel agents with improved efficacy. One of the major challenges is to
counter the ever-increasing drug and insecticide resistance in pathogens having effect on
epidemiological outcomes
[67]
. As part of the integrated malaria control program enhanced
vector control strategies, awareness of sanitation and waste management are being promoted.
Experts have pointed out that controlling the menace of malaria requires a multi-pronged
strategy rather than fighting it in isolation
[30]
. However, with advancement in science and
technology, tactics to control malaria have changed. It has led to development of new
technologies like, 1. A speculated global incidence of decrease in malaria cases; 2.
