As climate change Alters temperatures
and weather patterns around the world,
the risk of vector-borne diseases like
Dengue Fever, malaria and zika virus also
increasing in the recent years. the
number and range of mosquitoes has
boomed across North America,
and here is what that really means for
Global health, and what can be done to
limit the damage
between 2004 and 2006. the number of
diseases caused by insects or mosquitoes
witnessed a sharp rise. the spike rate
almost tripled during this period, and
still continues to grow since then.
according to the Center for Disease
controls division of vector-borne
diseases, virtually all vector-borne
diseases have a climate dimension,
and there are three key factors Rising
temperature affecting vectors, firstly
warmer temperatures make more places
suitable for vectors, heavy rainfall
increases the amount of stranding a
standing water ,which then creates more
breeding areas for many vectors ,likewise
droughts also contributing in their
increased geographical spread by forming
pools of standing water from previously
flowing water . in 2021 Arizona recorded
the largest outbreak of West Nile virus
in Maricopa County.
that here Arizona witnessed three times
more rainfall than usual. which
potentially facilitated a boom in the
mosquito population, leading to a rapid
virus spread more than 1400 cases were
reported ,representing Arizona’s largest
outbreak ever. secondly the change in
climate also leading to an increase in
the duration of the transmitted diseases,
meaning ones who are effective take more
than the normal time to recover.
extending the disease transmission
season, lastly temperature changes also
affecting the behavior pattern of these
vectors . Rising temperatures change the
biting behavior of mosquitoes, reducing
the effectiveness of barriers like bed
nets.
according to our 2019 study in the
journal
neglected tropical diseases by 2050.
this is carrying mosquitoes will
ultimately affect over 500 million more
people than they do today.
the spread will be responsible in
escalating
some of the most concerning infection
diseases like zika, Chikungunya ,West Nile
Virus ,and Dengue Fever . responding sooner
to the impact of climate change , use of
fossil fuels is an ultimate Way,
clean and renewable energy will help
lead us to a better future ,and will also
contribute in Saving Lives from other
climate crises, apart from that increased
health education, vaccine development and
disease management will also help in
combating the spread.
