Climate change could disrupt effective insect-borne disease control, research suggests

Climate change has been blamed for different environmental disasters including droughts, higher temperatures, climate change and warming oceans.

These are some of the worst effects of climate change that are made worse by human activities.

A new study has shown that climate change could also affect the behavior of mosquitoes, highlighting that it could affect efforts to tackle malaria in South Africa.

Malaria cases

The World Health Organization (WHO) has declared that malaria is considered a life-threatening disease.

The report notes that the parasites manage to transmit themselves to individuals. The transmission could come from bites.

The WHO added that more than 241 million cases of malaria were recorded worldwide in 2020, while deaths reached 627,000.

In addition, WHO explained that the African region accounts for 95% of malaria cases and 96% of deaths, with children also suffering from the disease.

Climate change and effective disease control

The report was published on the Phys.org website.

The article explained how climate change could impact the behavior and habits of mosquitoes.

Climate change has been a reason to alter the climate, weather conditions and rainfall land temperatures. With changing climatic factors, research explained that it would be difficult to effectively control insect-borne diseases.

With the threat expected to increase by 2035, the risks of malaria could increase as it is known to be happy at temperatures of 17⁰C and 35⁰C.

The report notes that South Africa has malaria cases in Limpopo (62% local cases), Mpumalanga and KwaZulu-Natal (6%).

What is alarming is how temperatures in South Africa have risen over the past 50 years. The report explained that the increase was unusual and faster than expected.

In the Southern Africa region, the report observed that the region is experiencing cooler days and more frequent extreme and harsh weather conditions.

Since mosquitoes like warm to warm temperatures, warmer weather could be helpful for them to thrive and infect vector-borne diseases.

Conversely, increased rainfall could contribute to increasing the number of mosquito breeding grounds.

While the article noted the direct impact of climate change on mosquito behavior, the report pointed to the unclear transmission of malaria.

Researchers are currently investigating how climate change could impact malaria cases.

Researchers are studying how climate change could affect efforts to end malaria. They showed important things to consider in the relationship between the two:

  • The researcher said the vector could grow faster as temperatures warm, noting that mosquitoes like warm temperatures.
  • It also shows that the mosquito could bite and infect more people due to increased reproduction.
  • As the weather or climate warms, the report notes that mosquitoes could enter or invade previously unsuitable areas.

Ultimately, the researchers pointed out that there was more to be done.

The researcher suggested the importance of targeted surveillance in malarial areas that could observe malaria transmission in different microclimates.

WHO added that some of the symptoms of malaria are fever, chills and headache, appearing 10-15 days after being infected, further explaining the importance of immediate medical attention once infected with malaria. .
