Why Africa can't afford to have an outbreak of the Zika virus

Why Africa can't afford to have an outbreak of the Zika virus | Virology News | Scoop.it
With limited laboratory capacity and a lack of experts and funding, an outbreak of the Zika virus in Africa could be problematic.
Ed Rybicki's insight:

Yeah...sure.  It could be Bad.

 

BUT: as South African epidemiologists have pointed out, it'll only be a problem IF the mosquito that transmits it elsewhere, comes here - because our local A aegypti doesn't have the same behaviour, and will vastly outnumber and possibly outcompete any import variety.

 

And it's endemic in tropical Africa - meaning many people are immune already.

 

So scaremongering about Zika in Africa is possibly a little irresponsible - unless it's being used as a stalking horse for an agenda for setting up continent-wide arbovirus surveillance, or spurring on efforts to set up an African CDC.  Which I would heartily endorse.

 

The stuff about lack of reagents is spot-on: which is why we have a proposal in the works to provide just such, using plants to it.  Watch this space....

8A Luiza 's curator insight, February 11, 2016 10:31 AM

From 2014 to the end of 2015, some countries of Africa had faced a horrible outbreak of Ebola hemorrhagic fever that killed too much people, leaving a shattered nation. Hunger, diseases, malnutrition and poverty are still found in a lot of parts of Africa. And now, how would an unprepared nation face another outbreak, a disease called Zika fever, that can dramatically affect the African continent?

 

According to the article, the Zika fever is a mosquito - borne viral disease caused by the zika virus which is suspected of leading to the birth of deformed babies, it is transmitted to humans when an infected Aides mosquito stings a person. Direct human to human transmission through sex has also been reported.

 

Nowadays, Africa is passing a very difficult moment, still have too much poverty in some countries of Africa, thus giving input to a lot kinds of diseases because unlike US, there is not an unified body of health experts on the continent, and no money to have all the necessary infrastructural and human capacity to diagnose Zika. It seems like a far reality of all of us, but this is OUR planet, we are all humans, and we need to find a solution for this huge problem. How can we spent so much money in many futile things, while we look to some parts of Africa and people are starring, dying from diseases that could be treated with simple remedies, but they do not have enough money to basic things.  The zika outbreak had already arrived in Brazil in a frightening amount and it will be in Africa not too late (if we consider the easy retention of diseases in places where hygiene and basic sanitation are precarious). How will the continent deal with it?

8B Claudia's curator insight, February 11, 2016 10:44 PM

This article from  "theconversation.com" adresses why Africa can't afford to have an outbreak of the Zika Virus. The Zika Virus is a mosquito-borne virus that has spread to 23 countries. It affected Brasil the worst, affecting 3700 people. People get the virus when an infected Aedes mosquito bites them which leads to symptoms, one which being suspected, deformed babies. Although many diseases and viruses attack Africa, this one they weren't prepared for. Some of the reasons are lack of experts, limited lab capacity, and no unified body. With the lack of experts, its harder to treat people and guide them what to do. Also, the laboratory capacity to test for the virus is limited so if somebody gets affected, they won't be able to know. The virus continues to spread however it will be hard to settle due to the lack of resources.


This article taught me more about the diseases/viruses that affect countries in Africa and how they are struggling with this outbreak. Since diseases/viruses hit Africa quite often, I'm surprised that they have a lack of many resources. Although it isn't deadly, I still hope they find a cure and are able to get more resources for when something like this happens again.

Whole genome, transcriptome, smallRNAome and methylome profiling during tomato-geminivirus interaction

Preguntas frecuentesManual de usoDerechos de autorContacto/Sugerencias Whole genome, transcriptome, smallRNAome and methylome profiling during tomato-geminivirus interaction Autor Romero-Rodríguez, Beatriz; Kriznik, Maja; Morilla, Ian; Petek, Marko; Jiao, Chen; [et al.] Fecha 2022 Palabras clave Virus fitopatógenos; Tomates - Enfermedades y plagas Resumen Geminiviruses constitute the largest family of plant-infecting viruses with small, single- stranded DNA genomes that replicate through double-stranded DNA intermediates. Because of their limited coding capacity, geminiviruses use plant nuclear machinery to amplify their genomes, which are packaged into nucleosomes forming chromatin as multiple circular minichromosomes. Thus, viral minichromosomes must encounter the nuclear pathways that regulate host gene expression and chromatin states. DNA methylation and post-transcriptional gene silencing play critical roles in controlling infection of geminiviruses and this pathogen can counteract these host defense mechanisms and promote its infectivity. Tomato Yellow Leaf Curl Virus (TYLCV) belongs to the Begomovirus genus and is transmitted by the whitefly Bemisia tabaci. With only seven viral proteins, TYLCV must create a proper environment for viral replication, transcription, and propagation. Behind the apparent simplicity of geminiviruses lies a complex network of molecular interactions with their host and their natural vector, which induces a wide variety of transcriptional, post-transcriptional and chromatin changes in the host. To better understand this virus-host interaction at a genetic and epigenetic level we carried out a global approach of the TYLCV-tomato interaction to generate integrated single-base resolution maps by Next-Generation Sequencing of the transcriptome, smallRNAome and methylome of the pathogen and the host. Total RNA and DNA was extracted from tomato–infected plants (three biological replicates) and analysed at 2, 7, 14 and 21-day post-infection (dpi). Analysis of the changes in host transcription during the infection and its correlation with changes in sRNA profiles (microRNA and phasiRNA) and DNA methylation patterns will be presented and discussed.
