A New and Horrifying Effect of COVID-19

The COVID-19 virus has been terrorizing innocent people from all corners of the world. The symptoms and effects of the virus have proven to be devastating especially for young children and the elderly. If that wasn’t bad enough, scientists have recently discovered that COVID-19 is linked to erectile dysfunction.

Let’s Talk About Malaria

Did you know, that the World Health Organization estimates that roughly 438,000 people die annually due to Malaria? Well, now you do know that unfortunate fact. But – did you know that the total number of people affected by malaria is only growing? In reality, those don’t matter, what does matter is what we are going to do now to combat the issue and CRISPR/cas9 might be the answer. In order to better understand the issue of Malaria and the resolution of utilizing CRISPR/cas9, let’s take an indepth look at both with the assistance of the article about Gene Editing to end Malaria from Vox.

 

So, what is Malaria? According to the Center for Disease Control, Malaria is a mosquito-borne disease caused by a parasite. The four kinds of malaria parasites that infect humans are Plasmodium falciparum, P. vivax, P. ovale, and P. malariae. Typical symptoms causes people to experience fever, chills, and flu-like illness. Left untreated, they may develop severe complications and die. Basically, Malaria has been affecting the global population for decades.  Now, you might be asking yourself: then, what is CRISPR/cas9? Fantastic Question! According to the National Institute of Health, CRISPR/cas9 is recent biomedical technology phenomenon that is drastically changing the genome editing space. In specifically, CRISPR/cas9, which is short for clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9, has generated a lot of excitement in the scientific community because it is faster, cheaper, more accurate, and more efficient than other existing genome editing methods.

 

So, here is the big question: why does it matter? Here is why it matters. When looking at Anopheles Gambiae Mosquito larvae, a common carrier of the Malaria parasite, in a lab in the United Kingdom, a couple of researchers noticed that all of the larvae had a physical red fluorescent phenotype. Although this doesn’t sound shocking, this is extremely shocking as only one parent had the red fluorescent recessive genotype and the other had the dominant wild type, so the expected offspring would be fifty percent with the red fluorescent gene and fifty percent without the red fluorescent gene, but all of the Mosquitos had the red fluorescent gene. This gene has been linked on Mosquitos to the fertility of female mosquitos. Now, you might be asking yourself: when does CRISPR/cas9 come into play? Well, CRISPR/cas9 can target and locate a specific gene, cut, enter itself in and then passed onto the abundant and constant offspring. As a result, when the CRISPR/cas9 is utilized to alter the mosquito population to be resilient to the Malaria parasite and could “wipe” Malaria from the future history of the planet.

 

In reality, I could never say that this is bad thing as it is working to save lives of hundreds of thousands of people globally. As a matter of fact, I would believe the majority of the population would say this is a good thing, but I am going to say this: do it, but do it right. This is something that needs to be done, Malaria has wreaked havoc on our global community for decades and we must move past that, but any small mistake would halt progress in this field for year. In conclusion, let’s keep having a serious discussion on changing the status of Malaria globally.

 

Thank you!
