How is everything going guys? :)We are back again! In this blog post, we will be sharing more about the background of HIV,main causes of HIV and how HIV is being spread. The source of HIV in humans was believed to have come from a type of Chimpanzee in West Africa. It is believed that the chimpanzee version of the immunodeficiency virus had been transmitted to humans when humans were on the hunt of Chimpanzee meat which resulted in them coming into contact with the infected Chimpanzee blood.The contacted virus from the Chimpanzees was then thought to have mutated into HIV which is the immunodeficiency virus found in humans.Currently HIV is being characterised into two types and they are HIV-1 and HIV-2. HIV-1 is known to be more virulent than HIV-2 and HIV-1 is largely responsible for the global transmissions of HIV. HIV is a virus that attacks a type of white blood cell in the body. This cell is known as a CD4 cell ( otherwise commonly known as the T-cell). These CD4 or T-cells are important cells in our body which are responsible for fighting off disease pathogens and infections so as to maintain a healthy immune system. As HIV is unable to reproduce by itself, it will enter the T-cells, make use of its cell replication machinery to replicate and make multiple copies of itself, before it breaks open from the T-cell. This process will result in the T-cells being destroyed. As the HIV replicates itself, more and more T-cells will be damaged and this in turn will result in the weakening of our natural immune system, resulting in a less effective immune system. Following the weakening of our immune system, the body will become more prone to developing infections. It will be unable to combat against foreign infections and cancers.Some of these infections developed can even be fatal.HIV can be spread when a person comes into contact with another infected person’s body fluid (e.g blood,semen, vaginal fluids or breast milk) via mucous membranes or direct contact with open skin/wounds. As HIV can be transmitted through amniotic fluid as well , a pregnant woman will thus be able to pass the virus to her baby too.

Alright guys, this pretty much sums up our second post on HIV. It’s really quite scary to think what HIV can do to your body right? Well, in any case, we hope you have enjoyed reading our post and do stay tuned for the next post whereby more information on how HIV affects individuals would be shared! :)
Till then,
Stay cool, stay healthy

0.0 Its scary alright.. That's why people should be extra careful.. Just think of how it will infect the next generation and how your child may suffer from this.. Its just so sad.. Immunodeficiency is the worst, our body is fighting for us all the time but as always, prevention is better than cure. Must take care of oneself!
ReplyDeleteMost definitely! Agreed! Thank you for the comment.
DeleteReally informative! Sneaky sneaky creatures!
ReplyDeleteSneaky creatures indeed! Thank you for the comment!:)
Deletecan kissing spread HIV? lets say that the infected person bit his tongue and theres blood while kissing, since theres an exchange of body fluid, can the partner get HIV ?
ReplyDeleteWow what an in depth question that's worth thinking about. Yes so in these cases, it's very likely that the partner that got kissed will contact HIV since logically speaking there has already been transfer of bodily fluid through an open wound. Thank you for your question,Sarah:)
DeleteSince its passed by body fluid, would that mean that it would be possible to pass HIV through sweat?
ReplyDeleteHi ra'uf, thank you for your comment. Since Sweat does not have CD4 cells, it is not able to transmit HIV! Phew phew, if not many of us would have already been contracted HIV! ;)
DeleteI'm 15 years old. I was born with HIV my mother passed away because of the HIV infection And I regret why i never met Dr Itua he could have cured my mum for me because as a single mother it was very hard for my mother I came across Dr itua healing words online about how he cure different disease in different races diseases like HIV/Aids Herpes,Parkison,Asthma,Autism,Copd,Epilepsy,Shingles,Cold Sore,Infertility, Chronic Fatigues Syndrome,Fibromyalgia,Love Spell,Prostate Cancer,Lung Cancer,Glaucoma.,psoriasis,Cirrhosis of Liver, Cataracts,Macular degeneration, Chrons disease,Infectious mononucleosis.,Cardiovascular disease,Lung disease.Enlarged prostate,Osteoporosis.Alzheimer's disease,psoriasis,Bipolar Disorder,Dementia.,Tach Disease,Breast Cancer,Blood Cancer,Colo-Rectal Cancer,Love Spell,Chronic Diarrhea,Ataxia,Arthritis,Amyotrophic Lateral Scoliosis,Fibromyalgia,Fluoroquinolone ToxicitySyndrome Fibrodysplasia Ossificans ProgresSclerosis,Weak Erection,Breast Enlargment,Penis Enlargment,Hpv,measles, tetanus, whooping cough, tuberculosis, polio and diphtheria)Diabetes Hepatitis even Cancer I was so excited but frighten at same time because I haven't come across such thing article online then I contacted Dr Itua on Mail drituaherbalcenter@gmail.com/ .
