This means the remaining 1,400+ municipalities in the country that participated in the survey are in a satisfactory situation.

Concerning cases of the respective viral infections, health officials report 1,458,355 dengue cases through Oct. 22. This is a decrease of 5.5% from the 2015 total during the same period in 2015 (1,543,000).

Considering the regions of the country, the Southeast and Northeast present the highest number of cases, with 848,587 cases and 322,067 cases, respectively. Next are the Midwest (177,644), South (72,114) and North (37,943).

The number of dengue related deaths are down significantly in 2016. The new epidemiological bulletin of the Ministry of Health presents 601 deaths by the disease in 2016, against 933 in the same period of the previous year. This represents a 35.6% reduction in dengue deaths in the country.

Brazil health officials have reported 251,051 suspected cases of chikungunya fever, of which 134,910 were confirmed.  In the same period last year, there were 26,763 suspected cases and 8,528 confirmed cases.

Chikungunya related deaths stand at 138, according to health officials.

There were 208,867 probable cases of Zika fever nationwide by October 22, representing an incidence rate of 102.2 cases per 100,000 inhabitants. Three laboratory deaths were confirmed in 2016 by Zika virus in the country.

The autochthonous, or local transmission of the virus in the country was confirmed as of April 2015, with laboratory confirmation in Bahia. The Ministry of Health has made compulsory notification of Zika cases in February this year.

The Southeast Region had 83,884 probable cases of the disease, followed by the Northeast (75,762); Midwest (30,969); North (12,200) and South (1,052).

    Aedes are not the only vector of Zika.Dr. Constância F. J. Ayres has researched this extensively and three independent teams of researchers from Brazil, China, and Canada have confirmed it.

    Another problem Wolbachia-based mosquito control and I found out tests were conducted in northern Australia (and other nearby regions). Wolbachia in Culex ENHANCES West Nile virus and Malaria (and probably does with Zika too).

    There is a frightening correlation (which I realize is not causation) between Culex (which also transmit Zika), Wolbachia, and whatever happens when these Wolbachia-Infected Aedes die (or are consumed).

    Incredibly, only the EPA needed to approve this permanent “experiment” (not the FDA). And safety studies were not carried out on birds, waterfowl, waterways, or Culex mosquitoes.

    Somehow the masses believe natural = safe (snake venom is natural). With over 30 citations: http://www.infobarrel.com/Wolbachia-Infected_Mosquitoes_Might_Reduce_Dengue_Enhance_Zika_and_Cause_a_Million_Souls_to_Become_Sterile
