A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations. #### What are the best certifications for project managers? The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation. #### How does PMI support career growth for professionals? PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers. #### What is the PMBOK® Guide? The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery. #### How is AI changing project management? AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment. PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes. #### What are the most important skills for a project manager? Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates. #### How can I get involved with the PMI community? Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions.

Health authorities in Japan [declared](https://www.asahi.com/ajw/articles/16071642) a nationwide flu epidemic on Oct. 3 after a wave of flu cases came five weeks earlier than expected for flu season, the country’s second-earliest flu outbreak in 20 years. [More than 4,000 people](https://www.mhlw.go.jp/content/001573336.pdf) in Japan were treated for influenza between Sept. 22 and Sept. 28\. The country’s Ministry of Health said that equated to an average of 1.04 patients per monitored medical institution, surpassing the threshold for an epidemic. The number of patients treated for influenza has [since increased to over 6,000 people](https://www.mhlw.go.jp/content/001576812.pdf) from Sept. 29 to Oct. 5, corresponding to a per-institution patient count of 1.56, more than double the per-institution patient count of 0.77 for the same period last year. Across the country, from Sept. 22 to Oct. 3, 135 schools and childcare centers closed, three times more than during the same period last year. Twenty-eight of Japan’s 47 prefectures [reported an increase](https://www3.nhk.or.jp/nhkworld/en/news/20251003%5F12/) in flu cases, with Okinawa reporting the highest patient per-institution count. But it’s not just Japan. Flu cases have risen in recent weeks in other countries across the continent, including Singapore, Thailand, and India. The latter, in particular, has been gripped by the spread of the H3N2 virus in the country’s north. The seasonal H3N2 descends from the strain that caused the 1968 Hong Kong flu pandemic, which had combined human and avian influenza viruses, Dr. Martin Beer, vice president of Germany’s Federal Institute for Animal Health, the Friedrich Loeffler Institut, told [DW News](https://www.dw.com/en/h3n2-influenza-spreads-rapidly-in-delhi-northern-india/a-74154442). The flu refers to an infection caused by any of the four types of influenza viruses A, B, C, and D, with influenza A and B causing the most common seasonal outbreaks in humans. While the flu and the common cold share many similar symptoms, the common cold can be caused by several different viruses, including rhinoviruses, according to the [U.S. Centers for Disease Control and Prevention (CDC)](https://www.cdc.gov/flu/about/coldflu.html). The rise in flu cases around the continent, as well as outbreaks in Europe earlier this year, have led some medical experts to warn that influenza may be evolving to spread more quickly or earlier than typical in some regions. “The flu season has started really early this year, but in the changing global environment this might become a more common scenario,” Yoko Tsukamoto, a professor at the Health Sciences University of Hokkaido, told the [_South China Morning Post_](https://www.scmp.com/week-asia/health-environment/article/3328124/japans-flu-season-hit-5-weeks-early-amid-fears-evolving-virus) about the epidemic in Japan. Nicola Lewis, director of the Worldwide Influenza Centre at the Francis Crick Institute in London, [warned](https://www.who.int/europe/news-room/feature-stories/item/there-is-one-certainty--there-will-be-another-flu-pandemic-in-the-future---an-expert-warns) last year that the next global pandemic could be caused by the flu. “I think the chances that disease X will be an influenza virus are probably greater than for any other known pathogen group that I can think of,” Lewis said. Disease X refers to a hypothetical new or unknown disease that can cause a pandemic. **Read More:** [_This Is One of the Worst Flu Seasons in Decades_](https://time.com/7221325/why-is-flu-season-so-bad-this-year/) ## Climatic and behavioral changes In Singapore, there has been a slight uptick in the number of cases with acute respiratory infections in the last two weeks, according to [data](https://isomer-user-content.by.gov.sg/18/cda9a4c0-a41b-4f51-8d15-412b2ca86cb8/Weekly%20Infectious%20Disease%20Bulletin%20EW%2039.pdf) from the country’s Ministry of Health, which monitors disease trends through sentinel surveillance sites including polyclinics and General Practitioner (GP) clinics. Predominantly, those cases have been the common cold rhinoviruses and influenza. There was also a spike in flu cases last month. Dr. Zhang Qi told [Channel News Asia](https://www.channelnewsasia.com/singapore/flu-cases-influenza-clinics-spike-weather-precautions-mask-vaccination-5337591) in September that he saw a “sustained and clear surge” of patients visiting his clinic for the flu. DoctorAnywhere, a network with both physical clinics and telehealth, also noted an increase of up to 40% in flu cases. Influenza cases are typically higher between December and March and between May and August, according to Singapore’s Communicable Diseases Agency. But the agency told CNA there’s no evidence that infections have been more severe than usual. Dr. Kimberly Fornace, an associate professor at the National University of Singapore’s school of public health, tells TIME that there are “clear seasonal patterns described for influenza in non-tropical areas,” with a higher incidence of flu cases typically reported in colder temperatures. At least part of that comes down to human behavior: “Influenza may transmit more easily when people are spending most of their time indoors during winter,” Fornace says. When it comes to tropical areas, though, she says there is “less understanding of these patterns.” But, anecdotally, there could be a similar pattern when it comes to wet weather. Some doctors say when the rainfall season hits in tropical countries like Singapore, people may similarly crowd indoors. Singapore has seen frequent late morning and afternoon thunderstorms in recent weeks as [inter-monsoon conditions](https://www.nea.gov.sg/media/news/advisories/index/more-wet-weather-with-onset-of-inter-monsoon-conditions-) set in. Thailand’s Public Health Ministry also warned of a surge in influenza cases in September. Between Sept. 7 and 13, data from the country’s Department of Disease Control [showed](https://www.nationthailand.com/news/general/40055746) more than 30,000 new influenza cases, bringing the country’s total this year to more than 555,000 with 59 deaths. That increase came as Thailand also saw [heavy rainfall amid its monsoon season](https://www.nationthailand.com/news/general/40054509), as well as [extreme weather](https://www.barrons.com/news/death-toll-from-thailand-monsoon-floods-hits-seven-d819768e) that has been exacerbated by climate change. There has been limited research into possible links between climate change and infectious diseases. A [2024 study](https://pmc.ncbi.nlm.nih.gov/articles/PMC11132621/) from researchers based in Singapore suggested that climate change, including heatwaves, higher rainfall, and tropical cyclones, can increase the transmission of some viral diseases, particularly vector-borne and food or water-borne diseases, as well as increase the growth and resistance of some bacteria. The study did not look specifically at influenza. Meanwhile, molecular biologist and science journalist Kai Kupferschmidt suggested in [_Science Magazine_](https://www.science.org/doi/10.1126/science.adl0413) that influenza epidemics may become less severe as the planet warms, but outbreaks may become more common, rather than season-dependent. “As epidemics become less severe in a warming climate, the virus is more likely to circulate yearround in many places,” Kupferschmidt wrote. Fornace, whose research focuses on the impact of environmental change on infectious disease dynamics, tells TIME that “the evidence is still mixed.” “There is definitely an effect of climatic conditions on spillover events from wildlife (for example, changes in wild bird migration patterns due to climate change),” Fornace says. “There are also some potential effects on the pathogen biology, such as survival and transmission rates under different environmental conditions.” But the clearest effects may be seen in how people alter their behaviors in relation to the changing climate. “We know that people spend different amounts of time indoors and have different movement patterns with different weather conditions,” Fornace says. “We have also seen major impacts of climate change across the region on health systems, particularly in response to extreme weather events where it can be difficult to continue to deploy routine health measures,” such as vaccinations. “The congregation of humans indoors may be an important factor to influenza epidemics, with adverse weather events being a driving factor. It is conceivable that with increased rainfall and higher population densities, we may actually observe an increase in influenza across all climates,” Dr. Sophie Dennis, a senior public health specialist at the World Health Organization and NUS, and Dale Fisher, a professor of medicine at NUS, [wrote](https://www.annals.edu.sg/pdf/47VolNo10Oct2018/V47N10p401.pdf) in 2018. ## Potential new variants Dr. Paul Tambyah, former president of the Asia Pacific Society of Clinical Microbiology and Infection, tells TIME that the emergence of new virus strains or variants is likely to be driving the increase in cases. The World Health Organization’s vaccine recommendations for the [2026 Southern hemisphere flu season](https://www.who.int/news/item/26-09-2025-recommendations-announced-for-influenza-vaccine-composition-for-the-2026-southern-hemisphere-influenza-season) included two strains that are different from the [2025 Northern hemisphere flu season](https://gisaid.org/resources/human-influenza-vaccine-composition/). The B/Austria/1359417/2021 (B/Victoria lineage)-like virus was included in both, while the new recommendations are A/Missouri/11/2025 (H1N1)pdm09-like virus and A/Singapore/GP20238/2024 (H3N2)-like virus. “This suggests that for both H1N1 and H3N2, there are drifted (or mutated) influenza strains circulating, which we may not be immune to if we got the previous flu vaccine or were infected in the last flu wave,” Tambyah says. “Hence the rise in flu cases in many parts of the world.” **Read More:** [_You Can Now Vaccinate Yourself Against the Flu_](https://time.com/7309719/flu-vaccine-home-flumist/) In Japan, health officials have suggested that the flu epidemic could be caused by commingling factors, including the return of mass tourism after a drop during the COVID-19 pandemic. “We are seeing a greater circulation of people, both in Japan and globally, with people taking the virus to new places, which is another factor behind the virus adapting to new environments,” Tsukamoto told _SCMP_. It’s not clear that the viral strain impacting Japan, Singapore, and other countries is the same, although Tambyah says it’s likely. Still, he cautions that influenza viruses may not be evolving at a significantly more rapid pace than typical as some have suggested. “The influenza virus has always had the ability to evolve rapidly to avoid immunity from either disease or vaccination,” Tambyah says. “Even the ‘normal’ pace of influenza virus evolution is hard to keep up with.” But he adds, “there is no evidence that this is happening any faster or slower.” Tambyah says scientists are closely watching the evolution of H5 and H7 or H9, subtypes of influenza A virus, in birds and animals. “The big concern is if a totally new strain of influenza emerges other than H1, H3, or Flu B, to which we have very little immunity,” Tambyah says. “This would lead to a pandemic like the H2N2 Pandemic of 1957.” Also known as the “Asian Flu” pandemic because of where it originated, that pandemic nearly 70 years ago killed an estimated 1.1 million people worldwide, including some 116,000 in the U.S., according to the [CDC](https://archive.cdc.gov/www%5Fcdc%5Fgov/flu/pandemic-resources/1957-1958-pandemic.html). Because of its recent rapid evolution and [detection in cattle in the U.S.](https://www.theverge.com/science/632605/forever-war-with-bird-flu), the [highly pathogenic bird flu](https://time.com/7205507/bird-flu-virus-mutating-death/) is particularly concerning, Lewis, the Worldwide Influenza Centre director, told the WHO last year. She warned that infections in mammals makes mutations that are transmissible to or among humans more likely. “Flu viruses can also undergo what we call re-assortment, which happens when 2 different flu viruses infect a person or infect a pig at the same time. They shuffle their genetic material so that the progeny flu virus that comes out of the pig or the human is actually different,” Lewis said. Pigs can be infected by avian, human, and swine influenza strains simultaneously, which makes reassortment especially likely, though the process is not exclusive to pigs. Referring to bird flu’s transmission to and dangerous infections in mammals, Lewis added, “We have never seen this kind of situation with a highly pathogenic H5 virus before. I certainly think that if you’d asked me in 2019, this would not have been the picture I would have conjured up in my mind about what bird flu could do.” ## Regular vaccinations could stay infections Experts across the board recommended keeping up with local flu vaccine schedules as a preventative measure. Tambyah says that there is no indication that the COVID-19 pandemic years led to an “immunity deficit” that might make people more susceptible to infections, pointing to the fact that death rates from respiratory illnesses have not changed significantly since pre-COVID years. In fact, he says the COVID-19 pandemic may have improved people’s awareness of respiratory infections and measures to prevent their spread, such as masking and washing hands. Yet despite the [success of COVID vaccines](https://time.com/5927342/mrna-covid-vaccine/), the pandemic also coincided with an increase in [vaccine hesitancy](https://pmc.ncbi.nlm.nih.gov/articles/PMC12344792/) or [distrust](https://www.bbc.com/news/articles/c1jgrlxx37do) worldwide, fueled in part by [anti-vax activism](https://time.com/7205900/anti-vaccination-movement-history/). “The fact that vaccination rates are still relatively low in many high income countries such as Singapore or Japan is a cause for concern, as vaccination with matching vaccines can reduce illness and potentially even death from complications of influenza,” Tambyah says. He adds that it’s important that institutions ensure employees “do not feel compelled” to go to work when they are sick to minimize the spread of viruses. **Read More:** [_When Should I Go to the Doctor With Cold Symptoms?_](https://time.com/7171353/when-to-see-doctor-appointment-health/) Ramanan Laxminarayan, an economist and epidemiologist who founded D.C.-based public health research organization One Health Trust, tells TIME that vaccination is particularly important for the elderly and other high risk populations.
