Malaria cases in city touch10-year high: MCD data
This comes amid a surge in the number of identified mosquito breeding sites having larvae — 9,117 more such sites were detected in the last seven days alone, which is more than a tenth of the overall number of sites (89,030) detected between January and July, MCD said in its report.
To be sure, the weekly case count on dengue and malaria cases is still low.
According to experts, while mosquito breeding is common in monsoon months, an above-average rainfall this July with multiple moderate to heavy spells and subsequent, lasting waterlogging across the city have likely contributed to the increase in this phenomenon. MCD has directed hospitals to reserve beds for patients to tackle the rise in cases of the two diseases.
Delhi added 16 new dengue cases in the past week, while 12 malaria cases were reported in the period.
The number of dengue cases till July 28 in 2024 was 284, 116 cases in 2023, 57 cases in 2022 and 29 cases in 2021. The number of malaria cases for the same period in 2024 was 106, 40 cases in 2023, 25 in 2022 and 15 cases in 2021.
The geographical distribution of dengue cases this year shows that the maximum number of cases have been reported from Central zone (38), followed by West zone (30), Civil Lines (29 cases) and Rohini, Shahdara, and South with 26 cases each.
Dengue is a viral infection transmitted to humans by the Aedes aegypti mosquito. While most infected people do not develop symptoms, those who do typically experience high fever, headache, body aches, nausea, and rash. Most recover within 1-2 weeks, but severe cases can be fatal due to haemorrhagic fever, which causes internal bleeding. The mosquito causing dengue breeds in clear water and waterlogged areas and the primary method of preventing the dengue is through breeding site reduction.
Delhi in July has received 259.3mm rainfall against the normal monthly average 209.7mm.
Meanwhile, civic officials said that the increased dengue cases count can be attributed to improved data collection from hospitals.
MCD is actively taking several measures to prevent and treat mosquito-borne diseases, which also includes chikungunya, said standing committee chairperson Satya Sharma.
'Hindu Rao Hospital, Swami Dayanand Hospital, and Kasturba Hospital have been declared as Sentinel Surveillance Hospitals for the treatment of mosquito-borne diseases. These hospitals have been equipped with special facilities — 70 beds have been reserved at Hindu Rao Hospital, 22 beds at Swami Dayanand Hospital, and 75 beds at Kasturba Hospital,' Sharma said.'All hospitals have already been directed to remain fully prepared for any emergency,' she said in a statement.

At 135, Delhi records the highest malaria cases in 5 years
Delhi has reported a spike in cases of malaria, with 135 recorded from January until August 2 this year, the highest in the last five years during the same period, according to civic body data. An additional 16 cases have been recorded with incomplete or wrong addresses. Delhi reported 115 malaria cases in 2024, 51 in 2023, 25 in 2022, and 16 in 2021 until August 2. The cases have risen sharply in the last five years, with 792 recorded in the previous year. According to MCD officials, the most common breeding spots for mosquitoes are coolers, drums, flower pots, money plants, fridge trays, discarded rubber tyres, and scrap lying in the open on rooftops. 'This is a very conducive environment for large mosquito breeding, and people should take preventive measures,' an official said. Meanwhile, 20 cases of chikungunya have also been reported, with the highest numbers reported from the West and Central Zones of MCD, with five cases each. Until last year, 23 chikungunya cases were reported during this period, but in the last five years, this vector-borne disease has seen a sharp rise, with four cases recorded in 2021, two in 2022, and four in 2023. However, an additional 15 patients have been recorded with incomplete or wrong addresses. As many as 267 cases of the disease were reported in 2024. As many as 291 people have been diagnosed with dengue, the deadly VBC disease, to which 11 people succumbed last year, with the Central Zone reporting the most number at 39. An additional 82 people remain with incomplete or wrong addresses. More than one lakh houses have been found positive for mosquitoes, and around 76,000 legal notices have been issued for mosquitogenic conditions.

Chikungunya surge in Mumbai: Here's why you should avoid self-medication
Chikungunya cases are surging in Mumbai, showing an upward trend. According to data from BMC's Epidemiology and Public Health Department Cell, a total of 265 cases of chikungunya were reported from January to July this year, compared to 46 in the corresponding period in 2024. Across Maharashtra, too, there has been a slight rise in cases of chikungunya with 1,512 cases reported this year as against 1189 in the corresponding period in 2024. Dr Daksha Shah, BMC's executive health officer, said the early onset of rain from May this year created a favourable environment for vector-borne diseases, resulting in a rise in cases. Concerns have been raised as chikungunya cases are spiralling in China, where an outbreak had infected 7,000 people since late June. The World Health Organisation (WHO), too, according to a recent update in June, has raised concerns about the ongoing spread of chikungunya in South Asia. What is chikungunya? It is an infection caused by the chikungunya virus, which is transmitted to humans by infected female mosquitoes, most commonly Aedes aegypti and Aedes albopictus, which can also transmit dengue and Zika viruses. These mosquitoes bite primarily during daylight hours. Aedes aegypti feeds both indoors and outdoors. While the overall fatality rate is low, severe disease can occur, especially in vulnerable populations such as infants, the elderly and those with pre-existing conditions. What about symptoms, how long does the infection last? It is characterised by an abrupt onset of fever, frequently accompanied by severe joint pain, muscle pain, headache, nausea, fatigue and rash, all of which are also common to dengue and malaria. 'The infection is self-limiting but joint pain is the standout symptom. It is debilitating and lasts for a minimum of three months although you may recover in a week,' says Dr Rajesh Gadia, consulting physician at KEM Hospital, Pune. Dr Shashank Joshi, consulting physician with Lilavati Hospital, says in a season of fevers with overlapping symptoms, it is best to consult doctors and avoid self-medication. What about treatment and vaccines? Fever and joint pain are addressed with antipyretics and analgesics, drinking plenty of fluids and general rest. There is no specific antiviral drug. Two vaccines have received regulatory approvals but are not yet widely available nor in widespread use. Chikungunya has seasonal trends 'Chikungunya epidemics display cyclical and seasonal trends. There is an inter-epidemic period of four to eight years (sometimes as long as 20 years). Outbreaks are most likely to occur in the post-monsoon period when the vector density is very high,' says Dr Rakesh Mishra, Director, Tata Institute for Genetics and Society, Bengaluru. What about prevention? Aedes aegypti breeds in stored fresh water in an urban and semi-urban environment. 'It is important to reduce such breeding sites. These are also daytime mosquitoes. Hence it would be a good idea to protect your legs and wear full-sleeve shirts when at work, during shopping or at the cinema hall, because that is where mosquitoes will find you. Use mosquito nets,' Dr Mishra says. These mosquitoes have a very short flight of a few hundred metres, so they don't spread very fast over long distances. 'Hence there is a localised spread of the disease, generally near the favourable breeding conditions,' Dr Mishra adds.

China Reports More Than 7000 Chikungunya Cases: Symptoms, Risk Factors, Complications And More
More than 7000 cases of chikungunya have been reported in China. Guangdong province in China is the worst-hit area, reporting the maximum number of cases. The US Centres for Disease Control and Prevention (CDC) has issued a Level 2 (Practice Enhanced Precautions) travel alert for all Americans travelling to China. The CDC has also recommended vaccination for travellers visiting an area with a chikungunya outbreak. For the unversed, chikungunya is a viral vector-borne disease. It is transmitted to humans through the bite of infected mosquitoes, primarily the Aedes aegypti and Aedes albopictus species. The virus doesn't spread from person to person through close contact, however, blood transmission may be possible. What are the symptoms of chikungunya? Chikungunya is characterised by a sudden onset of fever and severe joint pain. The incubation period is typically 3-7 days. High fever Severe joint pain and swelling Muscle pain Headache Fatigue Rash Severe joint pain is one of the distinct symptoms of chikungunya, which may last for weeks, months and even years. Older adults or those with pre-existing conditions are also likely to experience severe joint pain, especially during extreme weather conditions. Other symptoms are generally self-limiting and improve within a week. What are the treatment options for chikungunya? Chikungunya treatment mainly focuses on relieving symptoms. Anti-inflammatory medicines and pain killers are usually used to manage fever and joint and muscle pain. Rest and adequate hydration also assist in quick recovery. Is chikungunya fatal? Chikungunya is rarely fatal. However, the elderly, newborns or individuals with pre-existing health conditions remain at a higher risk of severe complications. Most symptoms are generally self-limiting and last for 2-3 days. The disease is characterised by an abrupt onset of fever, which is frequently accompanied by joint pain. Other common signs and symptoms include muscle pain, headache, nausea, fatigue and rash. How to prevent chikungunya Chikungunya prevention involves reducing mosquito exposure and controlling mosquito populations. Effective strategies include: Use insect repellent containing DEET or eucalyptus oil, especially when outdoors Wear long-sleeved clothes and full-length pants to minimise skin exposure Use mosquito nets while sleeping, especially in areas where chikungunya is prevalent Eliminate standing water, as this is where mosquitoes breed Install screens on windows and doors to keep mosquitoes out Stay indoors during peak hours when mosquitoes that transmit chikungunya are most active, especially at dawn and dusk. According to the World Health Organisation, the chikungunya virus was first identified in the United Republic of Tanzania in 1952 and subsequently in other countries in Africa and Asia. Urban outbreaks were first recorded in Thailand in 1967 and in India in the 1970s. Currently, there are two chikungunya vaccines available in the United States: IXCHIQ (a live-attenuated vaccine and VIMKUNYA (a virus-like particle vaccine).
