An open-access report in the journal Biocontaminant [PDF] describes a sudden, large increase in the number of infections with the chikungunya virus in southern China, with more than 4,000 cases in Foshan City, Guangdong Province, and over 3,600 cases in Shunde District. The initial spread of the outbreak was observed in this region and quickly escalated into a major public health concern. These cases have not only been documented in Guangzhou, Shenzhen, Yangjiang, and Zhanjiang within Guangdong Province but have also emerged in Macao and Hong Kong.
Let’s pretend for a moment that Intelligent Design Creationism accurately describes reality — that a supernatural entity, indistinguishable from the supposedly omnibenevolent god of the Bible, is continually intervening in living organisms to ensure they conform to a divine plan for the world, particularly for human life.
Let’s also assume that William A. Dembski, Michael J. Behe, and other “CDesign proponentsists” are correct in asserting that the presence of “irreducible complexity” and particularly “complex specified genetic information” is evidence of the work of this putative designer.
How, then, does this announcement about the increase in cases of chikungunya in southern China fit into that worldview?
Chikungunya is a virus transmitted to humans only through the bite of a female Aedes mosquito when she takes a blood meal — in much the same way that Zika, yellow fever, and malaria are transmitted. Once infected, a person develops a sudden-onset fever with painful joints and acts as a reservoir for the virus, enabling the next mosquito to pick it up and continue the chain of infection.
The recent increase in cases is believed to be due to two main factors:
- More viruses circulating in the population
- More Aedes mosquitoes, with a northward spread driven by global warming
Furthermore, the feeding strategy of the Aedes mosquito is a striking example of a finely tuned process: if any part of it fails, the entire transmission cycle collapses. By Michael J. Behe’s own definition, this appears to meet the criteria for “irreducible complexity” and, within that framework, would be touted as conclusive evidence of “intelligent design”.
The inescapable conclusion, then — if we accept the Intelligent Design worldview, in which a divine intelligence is the only possible explanation for such genetic information and irreducibly complex systems — is that both the virus and the mosquito have been intelligently designed to cause human suffering. They seem to have no other purpose than to reproduce themselves and increase infection levels within the population. In other words, according to the logic of ID creationism, this virus was designed with malevolent intent.
The Chikungunya virus.The outbreak and its public health implications are the subject of a news item from the Biochar Editorial Office, Shenyang Agricultural University, released through EurekAlert!The Chikungunya virus (CHIKV) is an arthropod-borne virus (arbovirus) of significant global health concern. It causes a disease characterised by fever and severe joint pain and has shown a marked capacity to spread rapidly in suitable conditions. Here is a summary of key information:
Chikungunya virus seen under an electron microscope.
Taxonomy and Classification
- Virus name: Chikungunya virus (CHIKV)
- Family: Togaviridae
- Genus: Alphavirus
- Genome: Single-stranded, positive-sense RNA (~11.8 kb)
- Structure: Enveloped, icosahedral capsid, approximately 60–70 nm in diameter.
Origin and History
- First identified during an outbreak in Tanzania in 1952.
- The name “chikungunya” comes from the Kimakonde language, meaning “that which bends up” — a reference to the stooped posture caused by joint pain.
- Originally confined to Africa and parts of Asia, the virus has since spread to the Americas, Europe, and the Western Pacific, largely due to international travel and vector expansion.
Transmission
- Primary vectors: Aedes aegypti and Aedes albopictus mosquitoes.
- Transmission cycle:
- A mosquito bites an infected human.
- The virus replicates inside the mosquito (extrinsic incubation period ~2–10 days).
- The mosquito transmits the virus to another human through a subsequent bite.
- Reservoir: Humans serve as the main reservoir during outbreaks; some sylvatic cycles exist in Africa involving non-human primates.
Symptoms and Clinical Presentation
- Incubation period: 2–12 days (typically 4–7).
- Common symptoms:
- Sudden onset of high fever
- Severe joint pain (often in wrists, ankles, and small joints)
- Headache
- Muscle pain
- Rash
- Fatigue
- Joint pain can persist for weeks or months in some patients, occasionally years.
- Fatalities are rare but can occur, particularly in the elderly, newborns, and immunocompromised individuals.
Epidemiology
- CHIKV outbreaks occur in tropical and subtropical regions but are expanding into temperate areas due to climate change and the northward spread of mosquito vectors.
- Major outbreaks have occurred in:
- India (2006 onwards),
- Réunion (2005–2006),
- Italy (2007, 2017),
- The Caribbean and the Americas (since 2013),
- China (recent increases, particularly in Guangdong Province).
- Outbreaks can be explosive, affecting 30–75% of the exposed population.
Diagnosis
- Laboratory methods:
- Reverse transcription PCR (RT-PCR) for viral RNA detection (acute phase).
- Serology (IgM and IgG antibodies) — useful after the first few days of illness.
- Differential diagnosis often includes dengue fever and Zika virus disease, as symptoms can overlap.
Treatment
- No specific antiviral treatment currently exists.
- Management is supportive:
- Analgesics and antipyretics
- Hydration
- Rest
- Non-steroidal anti-inflammatory drugs (NSAIDs) may be used for joint pain (after excluding dengue to reduce bleeding risk).
Prevention and Control
- No licensed vaccine is yet widely available, although several candidates are in clinical trials.
- Control relies on:
- Reducing mosquito populations (larval source control, insecticides, biological control).
- Personal protection (repellents, clothing, bed nets, window screens).
- Rapid detection and response to outbreaks.
Evolutionary and Genetic Features
- CHIKV exists as three main genotypes:
- West African
- East/Central/South African (ECSA)
- Asian
- Mutations in the E1 envelope glycoprotein (notably the A226V mutation) have enhanced transmission efficiency by Aedes albopictus, contributing to global spread.
- The virus can adapt rapidly to new ecological niches, which partly explains its recent expansion.
Public Health Importance
- Chikungunya is classified as a re-emerging infectious disease.
- High attack rates can overwhelm health services during outbreaks.
- Economic impacts include loss of productivity due to prolonged joint pain.
- Climate change, urbanisation, and increased travel are likely to drive further expansion.
Guangdong faces largest chikungunya outbreak on record
A new editorial in Biocontaminant reports that Guangdong Province is experiencing the largest outbreak of chikungunya fever ever recorded in China, with more than 4,000 confirmed cases since late July. Shunde District of Foshan alone has reported over 3,600 infections, and cases have also spread to Guangzhou, Shenzhen, Hong Kong, and Macao.
Chikungunya fever is transmitted by Aedes mosquitoes, the same vectors responsible for dengue and Zika. The disease, marked by fever and severe joint pain, does not spread directly between people, making mosquito control the key to prevention.
The outbreak reflects both the global spread of chikungunya and the favorable conditions for mosquito-borne diseases in southern China.

Authorities have launched a province-wide campaign urging residents to remove stagnant water and reduce mosquito breeding sites. The editorial also stresses that climate change, urbanization, and global travel are expanding the reach of arboviruses worldwide, posing growing public health challenges.
The World Health Organization has recently introduced updated clinical guidelines and reinforced its Global Arbovirus Initiative to strengthen monitoring, prevention, and coordinated response. The authors call for investment in genomic surveillance, community engagement, and international cooperation to mitigate future outbreaks.

Of course, when examined through the lens of evidence-based science rather than faith-based dogma, the chikungunya outbreak is entirely explicable in naturalistic terms. A virus adapting to a changing environment, assisted by a vector whose range is expanding due to climate change, fits perfectly with what evolutionary biology predicts — and requires no appeal to supernatural agency.
By contrast, if one insists on attributing every biological adaptation to an intelligent designer, then one must also accept that this same designer is deliberately engineering disease and suffering on a mass scale. This is the inevitable theological corollary of the Intelligent Design position: not benevolence, but calculated cruelty.
Outbreaks such as this are stark reminders of how interconnected human health, environmental change, and evolutionary processes are. They also underscore why understanding these relationships through science is essential if we are to mitigate their impact, rather than explaining them away with comforting fictions.

What Makes You So Special? From The Big Bang To You
How did you come to be here, now? This books takes you from the Big Bang to the evolution of modern humans and the history of human cultures, showing that science is an adventure of discovery and a source of limitless wonder, giving us richer and more rewarding appreciation of the phenomenal privilege of merely being alive and able to begin to understand it all.
Ten Reasons To Lose Faith: And Why You Are Better Off Without It
This book explains why faith is a fallacy and serves no useful purpose other than providing an excuse for pretending to know things that are unknown. It also explains how losing faith liberates former sufferers from fear, delusion and the control of others, freeing them to see the world in a different light, to recognise the injustices that religions cause and to accept people for who they are, not which group they happened to be born in. A society based on atheist, Humanist principles would be a less divided, more inclusive, more peaceful society and one more appreciative of the one opportunity that life gives us to enjoy and wonder at the world we live in.
