China reports over 7,000 Chikungunya cases, US CDC issues travel warning: Know what is Chikungunya, its symptoms
Chinese health officials have said that the worst affected city in the Guangdong province is the southern city of Foshan with most cases. Some of the measures for those affected by the mosquito-borne virus in Foshan include that patients remain in hospital, their beds will be protected with mosquito nets. Patients of Chikungunya cannot leave the hospital until they test negative or after a week-long stay.
The Chikungunya virus is, however, a rarity in China and the outbreaks are more common in South and South East Asia and parts of Africa. The US Centers for Disease Control and Prevention (CDC) issued a warning for travellers due to the mosquito-borne virus being transmitted in parts of southeast China.
The Chikungunya disease is caused by the Chikungunya virus which spreads through infected female mosquitoes, most commonly the subspecies Aedes aegypti and Aedes albopictus, which are the same type of mosquitoes that spread Zika and Dengue virus.
Chikungunya outbreaks have occurred in countries in Africa, Americas, Asia, Europe, the Caribbean, and Indian and Pacific Oceans. In a troublesome update by the US CDC, there is no specific treatment for chikungunya.
When a mosquito feeds on an infected person, it ingests the virus and can transmit it to other humans. The onset of the virus is usually four to eight days after the infected mosquito bites the person. People with risk of more severe disease include newborns infected around the time of birth, older adults (65 years or older), and people with medical conditions such as diabetes or heart disease.
Those infected with Chikungunya virus typically show symptoms 3-7 days after a bite by an infected mosquito. The most common symptoms are fever and joint pain. According to WHO, Chikungunya virus can also cause muscle pain, headaches, nausea and rashes.
The CDC says most people get better within a week's time but some can have severe joint pain for months to years following acute illness.

Dementia: Neurosurgeon wants you to know about high BP, diabetes and other CDC-backed risk factors
Dementia is a condition that affects how the brain works—especially when it comes to memory, thinking, and reasoning. It's not just 'forgetting things' like where you put your keys; it's more serious and can interfere with daily life. Tired of too many ads? go ad free now People with dementia might struggle to remember names, conversations, or even what day it is. Over time, it can get harder to plan, make decisions, or recognize familiar people and places. There are different types of dementia, but Alzheimer's disease is the most common. Others include vascular dementia, Lewy body dementia, and frontotemporal dementia. Each type has its own patterns, but they often share similar symptoms like confusion, mood swings, or trouble with speech. Dementia mostly affects older adults, but it's not a normal part of aging. Some people in their 40s or 50s can get it too, though that's less common. Things like family history, high blood pressure, diabetes, and lack of physical or mental activity can increase the risk. Recently, Dr Zayed Almadidy, MD, neurosurgeon shared a video where he has explained the different risk factors of dementia and how to prevent them. 'Very often, as a neurosurgeon, people ask me, 'What can I do to reduce my risk of developing Alzheimer's?' The CDC has found five different ways to reduce your risk of developing Alzheimer's. These are risk factors that have been clinically shown to increase your risk of developing Alzheimer's and dementia,' he explained. The doctor lists 5 risk factors: tobacco and alcohol use, hearing loss, high blood pressure, uncontrolled diabetes and lack of physical activity. Lack of physical activity Let's start with exercise—or the lack of it. Not moving your body enough doesn't just impact your heart and waistline; it also affects your brain. Tired of too many ads? go ad free now Physical activity boosts blood flow to the brain, supports memory, and helps reduce inflammation. People who live mostly sedentary lives are more likely to face cognitive decline as they age. The fix? You don't need to run marathons. Walking, swimming, dancing, or doing yoga a few times a week can make a big difference in keeping both your body and mind sharp. Uncontrolled diabetes If your blood sugar is all over the place, your brain may pay the price. Uncontrolled diabetes is a big risk factor for dementia. High blood sugar levels over time can damage blood vessels and nerves, including those in your brain. That damage can lead to memory issues and increase your chances of developing Alzheimer's or other types of dementia. Keeping diabetes in check with medication, healthy eating, and regular check-ups can really help protect your brain health. High blood pressure Think of your brain like a sponge, it needs a steady, healthy flow of blood to function well. High blood pressure (also called hypertension) can mess with that flow, putting strain on your blood vessels and increasing your risk of stroke, memory problems, and vascular dementia. The tricky part? High blood pressure often doesn't cause symptoms, so many people don't even know they have it. Getting regular blood pressure checks and managing it through diet, exercise, or medication can help protect your brain long-term. Hearing loss This one surprises a lot of people. Hearing loss, especially if left untreated, can increase your risk of dementia. Why? When your brain has to work harder to process sounds, it has less energy to focus on memory and thinking tasks. Plus, people with hearing problems often start to withdraw socially, which can lead to isolation—another dementia risk. If you've noticed your hearing slipping, don't ignore it. Getting tested and using hearing aids if needed can really help. Tobacco and alcohol use Smoking and heavy drinking are both major risk factors for brain health. Smoking reduces blood flow and oxygen to the brain, while alcohol—especially in large amounts—can actually shrink brain tissue over time. Even moderate drinking may raise your risk if you're already dealing with other health issues. Quitting smoking and cutting back on alcohol (or avoiding it altogether) can do wonders not just for your brain but your whole body. While there's currently no cure, early diagnosis and the right support can make a big difference. Medications, therapies, and lifestyle changes may help slow symptoms and improve quality of life. The doctor suggests physical activity, quitting smoking and alcohol, going for therapy, staying social and engaging in mentally stimulating exercises to prevent dementia risk.

Days after Jalandhar hospital deaths, Punjab govt to hire service providers to manage oxygen plants
Days after three deaths in Jalandhar civil hospital's ICU due to oxygen supply disruption, the department of health and family welfare is set to hire service providers for maintenance and management of biomedical installations, mainly oxygen plants, in the government health facilities across the per comprehensive annual maintenance service contract, the service providers will look after maintenance, management and operations of pressure swing adsorption (PSA) plants, liquid medical oxygen (LMO) tanks and medical gas pipeline systems (MGPS) including medical gas manifold, generator assembly, zeolite, electric panel and other ancillary items. Punjab health minister Dr Balbir Singh The department has already floated tenders for this, proposing a maintenance contract for three years, extendable by an additional two years, for 38 PSA plants and 33 MGPS units installed in government hospitals and medical colleges. Punjab health minister Dr Balbir Singh said the decision of hiring service providers has been taken to avoid Jalandhar hospital-like incidents in future. 'The service providers will ensure complete repair and maintenance of these units on regular basis besides maintaining complete record of repair, ensuring any sort of replacement, preventive maintenance on quarterly basis and calibration of machines,' the minister said. Dr Balbir added that the service provider shall ensure the availability of information, education & communication (IEC) standard operating procedure, checklist and log book related to operation, maintenance and safety of PSA and MGPS including manifold. 'Under this, the services engineers will be provided for rectification of complaints, besides ensuring regular testing and quality check,' he said. The minister added that the maintenance cost of PSA plants, installed during Covid under PM Care scheme, is very high and it is not financially feasible for its maintenance at hospital level. 'Due to the high maintenance cost of PSA plants, which produce medical-grade oxygen on the hospital premises, the department will ensure that LMO tanks and MGPS plants are fully operational in the government health facilities,' he said. On July 27, three patients, including a 15-year-old snake-bite victim, a 32-year-old drug overdose patient and a 30-year-old lung disease patient, died between 7.15 pm and 7.50 pm due to insufficient oxygen supply. Acting on the report of a probe team that pointed to gross negligence, the health department had suspended medical superintendent Dr Raj Kumar, senior medical officer Dr Surjit Singh and consultant anaesthesiologist Dr Sunakshi, while the services of Dr Shaminder Singh, the house surgeon, and technician Narinder Singh were terminated with immediate effect. The probe team found that instead of a technician overseeing the plant, a contractual ward attendant — a non-technical employee — was on duty when a malfunction in the plant caused the disruption of supply. He was ill-equipped to deal with the exigency, leading to the death of the three critically ill patients in the trauma centre.

Lok Nayak Hospital ex-director booked by CBI for irregularities
The Central Bureau of Investigation (CBI) has registered a case against Dr Suresh Kumar, former medical director of Delhi government-run Lok Nayak Hospital (LNH), and others for alleged criminal conspiracy, breach of trust, and misconduct by a public servant, officials said on Monday. The case pertains to alleged irregularities in a 2017 open tender floated by LNH on the Delhi government's procurement portal for sanitation consumables and non-consumables. (File photo) The FIR, filed on July 30, comes three years after a preliminary enquiry (PE) was initiated by the CBI in 2022 following reports of administrative lapses during Dr Kumar's tenure. According to officials, the PE has now led to the registration of a regular case (RC) after prima facie evidence was found. 'Prima facie offences under IPC Section 120-B read with Section 409 and Section 13(2) read with Section 13(1)(a) of the Prevention of Corruption Act have been disclosed against Dr Suresh Kumar and other former staff,' the FIR stated. HT has accessed a copy of the document. The case pertains to alleged irregularities in a 2017 open tender floated by LNH on the Delhi government's procurement portal for sanitation consumables and non-consumables, including macerators — machines used for hygienically disposing of human waste. The FIR alleges that only one firm was favoured repeatedly over an extended period, from the original contract period in 2017 until 2021, leading to 'undue benefits' to the firm and corresponding losses to the government. Eight macerators of 'inferior quality' were allegedly purchased at inflated prices, despite better-quality alternatives being available at lower costs. 'No fresh open tender was floated during the extended period,' the FIR adds, 'and extensions were granted to the same firm without justification -- from January 29, 2020, to July 13, 2021.' It also notes that the Covid-19 pandemic, often cited for emergency procurement, only began affecting India in mid-March 2020 -- two months after the original tender expired. The PE further flagged violations in medicine procurement norms. Under government policy, generic medicines -- which are more affordable and equally effective -- are to be prioritised over branded drugs. However, the FIR alleges that between April 7 and September 16, 2022, LNH procured medicines worth ₹32.23 crore from a local authorised chemist, of which ₹25.17 crore (approximately 80%) was spent on branded drugs, and only ₹7.05 crore on generic ones. 'This resulted in avoidable expenditure and reduced access to essential medicines for the public,' the FIR states. CBI officials said CCTV footage, procurement records, and other evidence are being examined to identify the officials involved in the decision-making process. So far, no arrest has been made in the case. Dr Kumar has not responded to messages and calls requesting comment on the matter till the time of going to print.
