The lead story — what happened
-
Kenya confirmed four new Ebola cases on Saturday, 17 October, bringing its total to seven.
[1] -
Kenya had never recorded an Ebola case before this month.
[1] -
One of the new patients is a relative of Kenya's first patient.
[1] The other three are health workers who treated him.[1] -
The first patient, a 40-year-old Kenyan man, travelled from Congo through Uganda to Nairobi without being caught at airport checks.
[3] He was diagnosed soon after a relative took him to hospital, and died on 5 October.[3] -
Ebola spreads through contact with an infected person's body fluids, such as blood or vomit.
[3] Anyone exposed can fall ill any time from 2 to 21 days later.[3] -
The second and third patients, both relatives of the first, were already in quarantine when they fell ill.
[3] [2] Both are stable and responding to treatment, Kenya's health ministry said.[1] -
Kenya listed 128 people the first patient had met.
[3] By 14 October it had found 113 of them, and 108 were in quarantine in Kenya.[3] Five had left the country.[4] -
Kenya's health ministry says it has quarantined most people at risk and sees no sign of the virus spreading among the wider public.
[1] -
Every Kenyan case is the Bundibugyo type of Ebola, which has no approved vaccine or accepted treatment, the World Health Organization says.
[1] Up to half of the people it infects can die, the United Nations says.[1] -
In Congo, where this outbreak began in May, more than 9,200 cases have been confirmed and more than 4,400 people have died.
[3] [1] -
Only just over a third of Congo's confirmed cases had been on a contact list before they fell ill, wrote an Ebola response leader at the International Rescue Committee, an aid group.

3 of 7
health workers among Kenya's seven Ebola cases
Who is involved
-
Kenya's health ministry
the Kenyan government department for health; it confirmed the cases and runs the tracing of contacts
-
Kenya's three infected health workers
staff who treated the country's first Ebola patient; now patients themselves
-
The World Health Organization
the UN's health agency; it says Bundibugyo Ebola has no approved vaccine or treatment
-
The International Rescue Committee
an aid group running health work in eastern Congo; its Ebola lead says most cases there were never on a contact list
How it unfolded
-
May Congo declares an outbreak of Bundibugyo Ebola
[3] -
5 Oct Kenya's first patient dies in Nairobi after travelling from Congo
[3] -
14 Oct a second case, a relative already in quarantine
[3] -
16 Oct a third case, a 65-year-old relative also in quarantine
[2] -
17 Oct four more cases, three of them health workers
[1]
Where this points
The next test is whether any new Kenyan case turns up in someone who was not already on a contact list, which would mean the virus has reached people nobody is watching.
What is pushing on the whole day
The bar and the word are our reading of how hard each one is pushing today. The arrow is where it is heading. The evidence is in the stories below.
In Congo, aid cuts forced one aid group to stop funding clinics in Ituri, which then lacked tools to spot Ebola early.
The CDC, the US public health agency, is sending a disease investigator and nearly $4 million to fight measles in Pennsylvania.
Shares in Syndax, a US drug company, fell 17% after its lung drug failed a trial.

02
CDC sends a disease investigator to Pennsylvania
The CDC, the US public health agency, said on Thursday it will send a scientist from its Epidemic Intelligence Service to help fight measles in Pennsylvania.
[13] It is also releasing nearly $4 million for the response, NBC News reported.[13] Pennsylvania had confirmed 1,222 measles cases and six deaths linked to the disease by Wednesday.[13] Lancaster County, the centre of the outbreak with more than 415 cases by 9 October, is the state's largest county without its own health department.[13] Why it matters — A county commissioner says she learns of new cases and deaths from the news, at the same time as the public.
[13] Without local staff, the work of finding cases falls on the state's central health system, which covers 60 of Pennsylvania's 67 counties.[13] -
03
The FDA sets up a board on drug protection
The FDA's drugs centre said on Friday it has set up a board to oversee its decisions on exclusivity.
[6] Exclusivity is a period after approval when cheaper copies of a new drug may not be sold.[6] It covers the five-year protection for a drug whose main ingredient was never approved before.[7] It also covers three years for an old ingredient approved again after new trials, and biological medicines.[7] It will not usually review the six-month protection for studies in children or the seven-year protection for rare-disease drugs.[7] - 1Studies in children0.5 yrs
- 2Old ingredient, new use3 yrs
- 3New ingredient5 yrs
- 4Rare-disease drug7 yrs
Four kinds of protection from copies, by length. The new board reviews the 3-year and 5-year kinds, not the other two. Why it matters — These decisions set how long a drugmaker can sell a medicine before cheaper copies arrive.
[6] The FDA says the aim is clearer, more consistent decisions.[7] -
04
Syndax's lung-scarring drug fails a trial
Syndax, a US drug company, said on 12 October that its drug axatilimab failed a mid-stage trial in idiopathic pulmonary fibrosis.
[9] That is a rare disease in which the lungs slowly scar and stiffen.[9] The drug did not slow the yearly fall in how much air patients could breathe out, compared with a dummy treatment.[9] Syndax's shares dropped 17% in trading after the market closed.[9] Why it matters — The same week, Bristol Myers Squibb, a large US drugmaker, said its own drug for the disease passed a final-stage trial, though only the lower of two doses worked.
[14] So one new drug for scarred lungs moved toward approval while another dropped out.[9] [14] -
05
Eye drops approved for blurry close-up sight
Viatris, a large drugmaker, said on 16 October that the FDA has approved its eye drops Ryzumvi for presbyopia in adults.
[8] Presbyopia is the slow loss of the eye's ability to focus on things close up, and most people notice it in their early to mid 40s.[8] The drops contain phentolamine and are also labelled for reversing pupils widened by other eye drugs.[8] Viatris sells them in the US under a licence from Opus Genetics.[8] Why it matters — Nearly everyone gets presbyopia with age, and Viatris is now looking for a US partner to sell the drops for it.
[8] Eye redness affected 21% of people in testing, and the company's statement gives no measure of how well the drops worked.[8] -
06
Agilent buys a pathology software maker
Agilent, a US maker of lab instruments, is buying Proscia for $240 million in cash, with up to $30 million more if targets are met.
[10] Pathology is the study of tissue samples to find disease, often cancer. Proscia makes Concentriq, software that stores and handles scanned images of those samples.[10] More than 4,000 labs, hospitals and drug companies use it.[10] The two firms agreed in 2022 to sell a pathology system together.[10] Why it matters — Agilent's chief executive, Padraig McDonnell, says pathology work is fast moving onto screens.
[10] Proscia's software lets outside AI programs help read those images, for drug research as well as for diagnosing patients.[10] -
07
Helen Branswell, an outbreak reporter, dies at 69
Helen Branswell, a reporter on infectious diseases for STAT, a US health news site, died on 13 October aged 69, of complications from cancer.
[11] She began covering germs during the 2003 SARS outbreak in Toronto.[11] On 31 December 2019 she posted that a ProMED alert, an email list where doctors report unusual illnesses, about unexplained pneumonias in China gave her SARS flashbacks.[11] That was before scientists had read the new virus's genes.[11] She and two colleagues were Pulitzer Prize finalists for their early Covid stories.[11] Why it matters — Experts and public health officials around the world respected her reporting on flu, polio, Ebola and Covid.
[11] [12] The head of the World Health Organization said her work was a trusted source of clarity at a time of false information.[11] -
08
Congo vaccinates health workers in Beni
Health workers and other front-line staff in Beni, a city in eastern Congo, were given the Ervebo Ebola vaccine on Friday.
[15] Ervebo worked in past outbreaks of the more common Zaire type of Ebola.[15] Whether it protects against the Bundibugyo type behind this outbreak is still being studied.[15] It is given under compassionate use, a rule that lets doctors use a medicine in a serious emergency before it is approved for that use.[15] About 50,000 doses are meant for front-line workers, and 20,000 more for a trial of whether it works.[15] Why it matters — Mohamed Janabi, the World Health Organization's director for Africa, said 2,400 people have survived Ebola in this outbreak with care such as blood, oxygen and antibiotics.
[15] The WHO says the outbreak is out of control and on track to pass the 2014-2016 outbreak in West Africa, which killed more than 11,000 people.[15] -

A blood test spots cancer left after surgery
Doctors at the Cleveland Clinic in the US tested the blood of 110 people after surgery for squamous cell cancers of the head and neck, in the skin or in the lining of the mouth and throat.
[16] The test looks for tiny pieces of DNA shed by tumour cells left behind, matched to each patient's own tumour.[16] People whose blood carried this DNA before follow-up treatment lived shorter lives and saw their cancer return more often over almost three years.[16] The test flagged 71% of the patients whose cancer came back.[16] Why it matters — Doctors now choose radiation or chemotherapy after surgery from the tumour's features, and the authors say most patients get too much or too little.
[16] The study, published on 18 October, followed patients at one hospital and was not a trial, so it can only shape the trials that would test the blood result as a guide.[16]
Why a disease is caught early only where someone is already watching
A new case can be stopped only if it turns up among people someone is already following, so a disease spreads fastest where nobody keeps the list.
The twist
A new case found inside quarantine is a sign the watching is working. A case that turns up outside the list is the real warning, because it was spreading while nobody looked.
The picture
How it works
- An outbreak is found one case at a time
- Health workers list everyone a sick person met
- Those people are watched for three weeks
- If one falls ill, they are isolated at once
- A case nobody listed spreads before anyone sees it
The same force, elsewhere today
Where this chain is also running, in today's other stories.
-
The CDC's investigator in Pennsylvania
Lancaster County has no health department of its own to list cases, so officials hear of them from the news, and the CDC is sending a person whose job is to find them.
-
Helen Branswell's death
She noticed the first Covid reports on 31 December 2019 because she was already reading ProMED, the list where doctors post unusual illnesses, and knew SARS from 2003.
Where you've seen this
Food poisoning
inspectors trace a sick diner back to one kitchen only if someone reports the illness
Forest fires
a lookout tower catches smoke early, and a fire in an unwatched valley grows unseen
A leaking pipe
a meter that someone reads shows the leak, and an unread one lets the water run for months
The catch
Watching only helps if it comes with somewhere to send the sick and the trust of the people being watched; in Congo many people with fever stay home because they fear the clinics.
And the whole of it
Each person in today's stories sees only the cases that reach them: health workers in a Nairobi hospital, a county official in Pennsylvania who finds out from the news. Nobody in that chain sees a whole outbreak, and a newspaper reader hears about each case last of all.
What is really going on
Kenya's Ebola cases went from three to seven in a day, and three of the new patients are health workers who treated the first man.
Why it works on us — A total of seven sounds small next to Congo's 9,200, and a small number makes it easy to miss that health workers falling ill is a different kind of case from relatives in quarantine.
Who gains
-
Kenya's government
— Finding its second and third cases inside quarantine lets it say there is no spread among the wider public and keep travel and trade open.
[1] [3] -
Drugmakers whose decisions the FDA board reviews
— A single board on exclusivity is meant to make decisions clearer, and those decisions set how long a medicine is sold without cheaper copies.
[6] [7] -
Viatris and Opus Genetics
— An approval for presbyopia lets them sell phentolamine drops to adults with a near-universal age-related eye problem.
[8] -
Proscia's owners
— Agilent pays $240 million in cash, with up to $30 million more if targets are met.
[10] -
Bristol Myers Squibb
— With Syndax's drug out, one fewer rival is chasing its own lung-scarring drug toward approval.
[9] [14]
Who pays
-
Kenya's health workers
— Three of the four new Ebola patients are health workers who treated the country's first case.
[1] -
Families in eastern Congo
— Aid cuts closed clinic funding that could spot Ebola early, and between a third and two thirds of deaths happen at home.
[5] -
People in Lancaster County, Pennsylvania
— With no local health department, cases there are found by a state system that covers 60 counties, and local officials hear of deaths from the news.
[13] -
Syndax shareholders
— The shares fell 17% after hours when the lung trial failed.
[9] -
People with idiopathic pulmonary fibrosis
— One of the drugs being tested for their scarred lungs failed to slow the loss of breathing power.
[9]
What nobody knows yet
Open questions from across today’s stories — ours included.
-
01
Whether Kenya's three infected health workers were on the contact list before they fell ill.
Kenya's health ministry named them as health workers who treated the first patient, but has not said whether they were already in quarantine, as the two relatives were.
[1] [3] [2] -
02
Where the 15 missing contacts of Kenya's first patient are, and whether any of them is ill.
On 14 October Kenya had found 113 of the 128 people he met, and the latest count does not say how many of the rest were found.
[3] [1] -
03
How many people the three health workers met before their illness was found.
Tracing of each new patient's contacts starts only after they test positive, and no list for the health workers has been published.
[1] [4] -
04
How many people have died of Ebola in Uganda during this outbreak.
The New York Times reports 20 cases and three deaths there, while the BBC reported that two people died.
[1] [3] -
05
How far Congo's outbreak has really spread.
Just over a third of Congo's confirmed cases were already known contacts, and between a third and two thirds of deaths happen at home, outside treatment centres.
[5] So the 9,200 confirmed cases may be well short of the real number.[5] [1] -
06
How many measles cases Lancaster County has now.
The latest county figure in the reporting, over 415, is from 9 October, and the county has no health department of its own to publish its count.
[13] -
07
Which drug decisions the FDA's new exclusivity board will take on first.
The FDA says the board will help with only certain cases and has not named any.
[7] -
08
How well Ryzumvi eye drops improve close-up sight.
Viatris's statement lists side effects but gives no figure for how much the drops helped in testing.
[8]
Kenya's second and third Ebola patients, two relatives of the first, were already in quarantine when they fell ill. Both are stable and responding to treatment.
Also true today
- The FDA approved Ryzumvi eye drops for presbyopia, the loss of close-up focus that most adults notice in their forties.
- The CDC is sending a disease investigator and nearly $4 million to help Pennsylvania fight its measles outbreak.
