‘Clean Kerala’ campaign: State government finally wakes up to over 100 fever deaths in 2017

More than 100 people have died of fever in 2017 alone, with official data from the Health Department revealing that around 14 lakh people were affected by communicable diseases this year. While 53 people have died of H1N1, there were 800 confirmed cases of swine flu. Data also showed that until June this year, there were 7,300 confirmed cases of dengue, with 13 people dying from the mosquito-borne disease. Health Department stats reveal there were 204,926 cases of Hepatitis A and B, and 295 cases of malaria. And while these numbers are only from government hospitals, the actual figures may be twice this, with a number of patients going to private hospitals in Kerala as well

Dealing with increasing cases of monkey malaria in humans

There are increasing reports of monkey malaria, most of which are due to P. knowlesi, and which has established itself as the fifth Plasmodium species that infects humans. It has not been determined whether P. knowlesi is naturally transmitted from one human to another by the mosquito, without the natural intermediate host (monkeys). As such, P. knowlesi is still considered a zoonotic infection. There were 4,553 and 204 cases reported from Sabah and Sarawak, and Peninsular Malaysia from 2004 to 2016 respectively. The infection has also been reported in Indonesia, Thailand, Myanmar, Singapore, the Philippines, Vietnam, Brunei and China with 465, 37, 33, six, five, three, one and one cases respectively

How rubber plantations are exacerbating the dengue outbreak in one north Kerala area

Many residents of Koorachundu, in Kozhikode district in north Kerala, have been affected with fever in the last three months. Media reports suggest that about 12,000 residents have been infected with some kind of viral fever in the panchayat, which has a total population of 17,000. The microcosm of the Koorachundu panchayat reflects the falling health standards across Kerala. Reports suggest cups used to collect latex from where rubber trees were grown are a breeding ground for mosquitoes. Another is the fact coconut farmers have not cleaned the crown of palm trees and the fibrous stalks remain a good habitat for mosquitoes

Pacific News Minute: Dengue Outbreak in Palau; Mumps in the Marshall Islands

At least a thousand mumps cases have been confirmed since an outbreak began in March. The Ministry of Health notes that the number of cases has been dropping in recent weeks, but Radio New Zealand reports concern that the drop could be due to under reporting and that the real number could be as high as three thousand. Three people are reported dead among 200 infected by Dengue fever in Palau. On a visit to Taipei, Health Minister Emais Roberts welcomed the donation of three intravenous infusion pumps and 240 canisters of mosquito repellent to assist in the epidemic

488 malaria cases in 17 days of June

At a time when the civic body and the state government have intensified their efforts to destroy mosquito breeding sites and curb spread of vector-borne infections, malaria cases appear to be on the rise. According to data of the civic body, Ahmedabad registered 488 cases of malaria in the first 17 days of June. AMC health officials have also confirmed that they have received complaints of polluted water supply from at least 10 areas in the city. The weekly health report of Ahmedabad Municipal Corporation (AMC) states that six more cases of vector-borne infections including four cases of dengue and one each of chikungunya and falciparum malaria were also registered during this period

Mosquitos infectados para atacar dengue alborotan polémica en Medellín

GM mosquitoes which have been bred to attack dengue and other diseases by the University of Antioquia in Colombia are being released in an experiment to see if they can control the mosquito borne viruses affecting the district. The project is facing some criticism as it appears to not be following WHO guidelines and using smaller scale studies, according to its critics

Ted 2017: Frugal scientist offers malaria tools

Manu Prakash, a bio-engineer at Stanford University, designs cheap tools that can make a big difference in the poorest parts of the world. At Ted, he showed off his latest gizmo – a cardboard centrifuge that can spot malarial parasites in blood. Toy-inspired, it costs 20 cents. He also launched a citizen science project to identify disease-carrying mosquitoes by their sound, called the ‘Abuzz Project’

Scientists plan to trick Zika-carrying mosquitoes into breeding themselves out of existence

This summer, a Silicon Valley tech company will have millions of machine-raised, bacteria-infected mosquitoes packed into windowless white vans, driven inland and released into the streets of Fresno, Calif. This year`s mosquitoes are being bred and distributed by Verily, a subsidiary of Alphabet that was formerly known as Google Life Sciences. Verily officials estimate that they will release 1 million mosquitoes per week in Fresno County, more than 25 times last summer`s numbers

Malaria ‘epidemic’ looms as mosquitoes defy insecticides

According to a study, genetic analysis of mosquito populations in Africa shows that recent success in controlling malaria through treated bed nets has led to widespread insecticide resistance in mosquitoes. Previous research indicates there are four classes of insecticides recommended for malaria control of which only pyrethroid was approved for use on LLIN. It has been shown that the loss of this insecticide’s effectiveness will lead to increase in preventable deaths, particularly in the most vulnerable groups, hence the need to maintain the effectiveness of LLIN in an era of growing resistance

New research finds light treatment may reduce mosquito bites at night

Scientists have found that exposure to just 10 minutes of light at night suppresses biting and manipulates flight behaviour of malaria mosquitoes. The findings, published in the journal Parasites and Vectors, suggest that light can be used to manipulate mosquitoes, thereby offering a potential novel solution to preventing bites and reducing malaria

Scientists kill malaria-carrying mosquitoes with genetically engineered fungi

A genetically engineered fungus, designed to produce toxins from spiders and scorpions, could effectively kill malaria-carrying mosquitoes, according to a new study. The fungus involved is known as Metarhizium pingshaensei, a natural killer of mosquitoes that was originally isolated from a mosquito. To boost its deadly power, researchers engineered the fungus to include several genes that express neurotoxins from spider and scorpion. "Our most potent fungal strains are able to kill mosquitoes with a single spore," a co-author of the paper, said. "We also reported that our transgenic fungi stop mosquitoes from blood feeding. This means our fungal strains prevent transmission of disease by more than 90 percent of mosquitoes after just five days"

Concern over Zika leads WHO to go for pilot programmes

Growing concern internationally over Zika persuaded WHO to develop carefully planned pilot programmes accompanied by independent monitoring and evaluation. Oxitec trials show a reduction in mosquito populations of above 90%. But as critics point out, that does not necessarily lead to a similar level of disease reduction. Other factors may sustain infection even with a smaller number of insects
