The Zika virus promises a new reality for the USA and ‘the rest of the world.’ The virus will be infecting more individuals in the coming months, and ‘the true tragedy’ becomes apparent for those not infected by the virus.
Many of us will do our best eliminate standing water and ‘dangerous hot spots.’
Otherwise, ‘some encouraging words’ come from the researchers–
Purported MECHANISTIC DETAILS of Zika’s Infection in humans and in animal models:
The word mechanism implies that researchers, doctors and most of the ‘informed community’ understands how the virus infects ‘new borns and adults.’ It is also called a ‘mode of action’ — in some circles.
The impaired neurogenesis (in the fetus) is the focus of research and the impaired growth of ‘neural stem cells.’ The virus causes what is termed as apoptosis–a death of cellular material. The precise ‘chemical mechanism’ is unknown… if it were known, the scientific community would know the best approach for deterrence. The public is justifiably upset, skeptical, confused and frightened. However, research is a slow and a precise affair in which progress –is marked by ‘repeatable and accurate experimentation.’
The entry point for the virus can happen at multi-sites –and can happen before, during and after ‘egg fertilization.’ The placenta– a safe haven– is, in this case, susceptible. The plea to the public is–be safe and minimize potential exposure.
Treatment Options (Future)… Detection? Vaccines? and Potential Therapies?
Presently, some in the medical community believe it will find a vaccine within two years while others speculate one year and even three years. The discovery of a vaccine hinges upon poorly understood aspects of the viral replication cycle and diagnosis of infection — an intimate knowledge its bio-chemical and mechanistic details is needed.
Diagnosis of viral infection has returned false negatives in some instances–a terrifying outcome. The reasons for diagnostic problems arise when one understands that Zika–is an arboreal virus– it is similar to Dengue Fever and West Nile with its mode of infection. Mosquitos, the culprits for much death, can carry other viruses. That is a challenge we face…
Presently, the medical community believes its best chance to contain the spread of the illness is through vaccination.
A vaccine for Zika is pursued in at least three ways: targeting DNA replication of Zika, modifying live viruses of Zika and modifying inactive Zika virus. There are a number of different strains of the Virus. Namely, the original 1947 virus (less problematic to people) transformed– aspects of its biochemistry changed from the Zika River Valley in Africa to its infectious form of 2007-08 Micronesia and the present infection of the Americas.
How a virus transforms would go far in understanding how to treat the infection. That type of mechanistic detail would expedite the path to vaccination and therapy.
Therapies, presently, are in planning stages. One route of investigation subverting viral replication —
The immuno-suppressor, Rapamycin is one potential candidate for therapeutic success. It subverts the immune system and may interfere with a viral replication.
As with many candidates such as Rapamycin, it is a ‘hot compound– toxic to many vital organs.’ However, in the war against pathogens, humanity can not afford to rest…
